MEANING OF THE TERM ‘WATER CYCLE’
Water cycle is the continuous movement of water on above and below the surface of the earth in different forms.
or
Water cycle is the continuous movement of water on, above and below the surface of the earth in different forms.
These forms can be liquid, gas or solid.
Since it is a cycle, there is no beginning or ending.
PROCESSES AND STAGES OF WATER CYCLE
Some of the processes and stages are evaporation, transpiration, condensation, precipitation, surface run-off and infiltration.
Evaporation is the loss of water from soil and water bodies into the atmosphere in form of vapour.
Transpiration is the loss of water from plant leaves into the atmosphere through plant openings in form of vapour.
The combination of evaporation and transpiration is called Evapotranspiration.
Evapotranspiration is the loss of water from the soil, oceans, lakes, rivers and plants into the atmosphere as vapour.
Condensation is the process by which water vapour in the atmosphere is changed into droplets. When there is an accumulation of water droplets clouds are formed.
Precipitation is the falling of water from the atmosphere to the earth in form of rain and hail. Precipitation is also called rainfall.
Surface run-off is the water that flows on the soil surface following the slope of the land.
Infiltration is the entry of water into the soil.
Percolation is the moving deeper of water in the soil increasing the amount of ground water.
Ground water refers to large amounts of water stored below the earth's land surface.
Open water bodies refers to water existing on the land surface such as rivers, lakes, ponds, oceans and dams.
UNIT 4 WATER POLLUTION
Pollution is the contamination of the environment with harmful and poisonous substances arising from human activities.
CAUSES OF WATER POLLUTION
EFFECTS OF WATER POLLUTION ON AGRICULTURAL PRODUCTION
FUTURE’S WHEELS SHOWING CONSEQUENCIES OF WATER POLUTION
WAYS OF CONTROLLING WATERPOLLUTION
WAYS OF KEEPING WATER SAFE
Water conservation refers to the ways of reducing water loss from soil allowing more water to infiltrate in the soil and collecting surface run-off for future use.
WAYS OF CONSERVING WATER
UNIT 6 SOIL TEXTURE
Soil texture is the coarseness or fineness of the soil.
or
Soil texture is the percentage of sand, silt and clay in a soil.
CLASSIFICATION OF SOILS BASED ON TEXTURE
There are three main classes of soil based on texture. These are sand, clay and loam soils.

Soil structure is how soil particles are held together.
or
Soil structure is the arrangement of soil particles to form different shapes.
CHARACTERISTICS OF DIFFERENT SOIL STRUCTURES
There are different types of soil structures. Some of these soil structures are loose, crumb and compact.
Loose structure
Crumb structure
Compact structure
Soil profile refers to the vertical section through the soil showing horizontal layer.
Most soils have four main layers.
These are top soil, sub soil, weathered rock and parent rock.
LAYERS OF SOIL AND THEIR CHARACTERISTICS
Top soil
Sub-soil
The washing down of nutrients from top soil to the sub soil is called leaching. Roots of most crops do not reach this layer.
Generally, the sub soil is less fertile than top soil.
However, some deep rooted crops such as trees may penetrate this layer.
Weathered rock
Parent rock
THE CHARACTERISTICS OF TOP SOIL THAT PROMOTE CROP PRODUCTION
Characteristics |
Importance for crop production |
high nutrient content |

black colour |
it helps the soil to absorb heat which provide warmth necessary for seed germination and seedling development |
high humus content |
humus improves soil aeration, water retention and nutrient content of the soil |
presence of soil organisms |
these help to improve soil aeration like earth worms |
UNIT 9 SOIL EROSION AND CONSERVATION
Soil erosion
Soil erosion is the removal of top soil by the action of water and wind.
CAUSES OF SOIL EROSION
EFFECTS OF SOIL EROSION
SOIL CONSERVATION
TERRACES ON STEEP SLOPE
Making terraces on steep slopes. This conserves soil by reducing the speed of running water.
MULCHING
Mulching material reduces the speed of running water which can carry soil away.
STRIP CROPPING
Strip cropping involves alternating strips of poor cover crops (maize) with good cover crops (groundnuts) across the slope.
The soil that has been eroded by poor cover crops is trapped by good cover crops.
RIDGES ACROSS THE SLOPE
Making ridges across the slopes reduces speed of run-off
BOX RIDGES
Making box ridges reduces amount of run-off by holding water in the boxes.
CONTOUR BANDS
Making contour bands holds water and reduces amount of run-off thereby controlling erosion.

TYPES OF FLOWERS
There are different types of flowers based on how they grow.
These flowers have stems which need support because the stems are weak and grow along the ground. The flowers look beautiful when supported by a wall, strings, trees and fences. Examples of the creepers are money plant, and bougainvillea.
These flowers have stems which do not grow tall. The stems do not need support. The flowers produce many side branches and cover the ground. Examples of such flowers are geranium, periwinkle, marigolds, zinnia, dahlia and ferns.
These flowers have stems that grow very big and tall. The stems are also tough. The trees are grown because they produce beautiful shape, fruits, petals and leaves. Examples of such flowers are jacaranda, acacia and conifers.
These have stems which are thick and tough after first year of growth. They produce many branches which can be trimmed to a variety of shapes. Examples of such flowers are hibiscus, roses, fushsia, and poinselta.

Transplanting should be done on a cool day or early in the morning or late in the afternoon to reduce loss of water from the seedlings.
UNIT 17 MANURE AND FERTILISER APPLICATION IN FLOWERS
FERTILISER AND MANURE APPLICATION TO FLOWERS
Fertilizers and manure are applied to flowers to encourage growth.
Different types of manure are applied such as compost manure and animal manure. Well decomposed manure should be applied.
The manure can be mixed with soil before transplanting.
When the flowers are well established, the manure can be spread (broadcasted) in the flower beds. Where the flowers are planted in the rows sparsely planted, the manure can be applied in grooves. The common fertilizers applied in the flowers are 23:21:0+4S and CAN.
The fertilizers are applied using dollop method, banding method and broadcasting method depending on how flowers are planted.
Apply 23:21:0+4S soon after transplanting. When flowers are well established apply CAN.
COMMON WEEDS IN FLOWER GARDENS
Some of the weeds in flower gardens are star grass, datura, oxalis, chisoso, Tridax, galisoga. A flower garden has to be free from weeds for it to be beautiful.
METHODS OF WEED CONTROL IN FLOWER GARDENS
In a flower garden, weeds can be controlled using the following methods:

PESTS AND DISEASES OF FLOWERS
Mealy bugs
These are found on undersides and axils of leaves and young shoots. They produce a sticky substance called honeydew on which grows a black mould. They live by sucking plant juices. They can be controlled by using clean planting materials.
Aphids
These cause twisting of leaves and flowers. They also produce sticky substances called honeydew that attracts ants. They can be controlled by using dimethoate or marathion, hot pepper and garlic.
Scaley insects
They are identified as bumps on stems and undersides of leaves where they produce substance called honeydew resulting in stunted growth. They live by sucking plant juices. They can be controlled by Marathion or Noadazinon.
White flies
They are found on undersides of the leaves and produce sticky substance called honeydew where a black mould can develop. They live by sucking plant juices. They can be controlled by clean planting materials.
Spider mites
These are found on the undersides of the leaves. They suck plant juices. They can be controlled by interplanting with strong smelling plants like marigold and using Dimethoate, Actellic and Rogor.
Slugs or Snails
They are found around dark, moist, decaying matter. They eat leaves. They can be controlled by hand picking or use of sodium bicarbonate and common salt.
Beech bark disease
Giant polypore fungus
There are three products that can be harvested from flowers and shrubs. These are:
PROCEDURE
The best stage to harvest or cut flowers for sale depends on the types of flowers. Generally, flowers must be harvested just before or as soon as they reach maturity. The bud should not be completely open.
Cut the flowers during the cool morning hours. At that time dew should dried.
Use a pair of scissors, garden share, secuture and knives to cut the flower. These materials should be kept sharp to ensure that stems are cut evenly and not crushed. Crushed stems restrict the ability of the flowers to take up water thereby reducing their life.
PRESERVING FLOWERS
Flowers are cut at uniform length and hang upside down in branches in a dark, dry room to prevent fading of colour through sunlight
Flowers are pressed between newspapers. Alternating layers of flowers and paper are pressed between two boards. A heavy object is then placed on the top board. The pressed flowers are usually stored in the stuck until needed.
Flowers are dipped in a solution of water and glycerine for two to three weeks.
Freshly harvested flowers should be placed in lukewarm water that has floral preservatives. The preservatives increase flower's life.
Silica gel absorbs moisture from flowers. Flowers are placed in a closed container with silica gel. It is recommended that flowers dried in this way should be stored and displayed in the closed containers to keep out moisture.
TYPES OF VEGETABLES
There are two main types of vegetables. These are indigenous and exotic
Indigenous vegetables
These are vegetables found naturally in a country for example Malawi.
These include chisoso, mwanaaligone, luni, bonongwe, limanda, thugwi, chewe, bowa and njerenjedza.
Exotic vegetables
These are vegetables introduced in a country from elsewhere.
These include cabbage, rape, carrot, tomato, bowa and eggplant.
CLASSES OF VEGETABLES
Vegetables can be classified according to edible parts. The following are the classes of vegetables:
Leaf vegetables
Cabbage, mustard, bonongwe, rape and spinach.
Root, tuber and bulb vegetables
Carrot, European potatoes, onion, sweet potatoes and beetroot.
Fruit vegetables
Tomatoes, eggplants, pepper, pumpkins, cucumbers.
Legume vegetables
Peas and fresh beans, fresh cowpeas
For some vegetables the whole plant is eaten such as mushroom.
IMPOTANCE OF VEGETABLES
UNIT 23 NURSERY ESTABLISHMENT AND MANAGEMENT FOR VEGETABLES NURSERY ESTABLISHMENT
Some of the activities involved in vegetable nursery establishment are site selection, seed selection, seed bed preparation and sowing.
SITE SELECTON
A vegetable nursery should be near a water source near the home or school for easy management and on sandy loam soil for easy drainage
SEED SELECTION
It is important to select good seed for sowing to ensure high germination percentages and health strong seedlings.
Seed can be selected from previous crop or bought.
Check the expiry date to avoid buying seeds which have overstayed as this will lead to low germination percentage.
NURSERY BED PREPARATION
After selecting site for a vegetable, it must be fenced.
The land must be tilled to a depth of more than 15cm to loosen the soil and improve the drainage. The bed should be 1 metre wide and 15 cm high.
A bed can be of any length.
The bed must be flat to avoid run-off.
Make a mixture of two parts of loam soil, one part manure and one part sand. Spread the mixture over the bed to a depth of 15 cm.
SOWING SEEDS
Large vegetable seeds as those of pumpkins, peas and beans can be sown directly on the field beds.
Small seeds should be sown in furrows (drills) 1.5 cm deep and 10-20cm apart along the width of the seedbed in straight lines for easy management and extraction.
Spread the seeds thinly in the furrows and cover lightly with soil. Erect a raised mulch which will also serve as a temporary shade.
NURSERY MANAGEMENT
Vegetable nursery management involves a number of activities.
These activities include watering, weeding, thinning, pest and disease control and hardening off.
Watering
Water seedbeds in the morning and late in the afternoon everyday until the seedlings are four weeks old.
Avoid watering at midday when evaporation is highest.
Avoid under-watering because it will result into wilting.
Weeding
Weeding is necessary to reduce competition between weeds and seedlings for nutrients, water, light and space.
It also reduces the attack by pests and diseases.
Hand weeding is recommended to avoid damaging roots.
It is necessary to make the soil loose using a small, sharp stick or a hand folk.
Thinning
Thinning can be done when there are too many seedlings in the farrows (drills). Seedlings may be thinned to 20cm apart when they are about two weeks old.
PEST AND DISEASE CONTROL
Seedlings have to be protected from pests and diseases. Some pests of vegetable seedlings are caterpillars, grasshopper, nematodes and aphids.
PEST CONTROL IN VEGETABLE NURSERY
PEST |
CONTROL |
Aphids |
spray marathion |
grasshoppers |
spray Carbaryl |
cutworms |
drenching the soil with actellic 1ml in 1 litre of water |
caterpillars |
spray Carbaryl at a rate of 85g in 14 litres of water |
All these pests can be controlled by spraying with tephrosia or using smelly mulching materials like lemon grass, mpungabwi or plant strong smelling crops for example garlic.
DISEASES
Dumping off is one of the common diseases in the vegetable nursery. It is caused by fungus and promoted by overwatering.
It can be prevented by:
ª sowing at recommended spacing
ª sterilising the soil before sowing
ª dusting the seed with a fungicide such as captain and thiram
ª frequent weeding
ª avoid overwatering
HARDENING OFF
This is the gradual reduction of frequency of watering to seedlings.
This is done to prepare seedlings for the hot and dry condition in the garden.
The temporary mulch should be removed in the second or third week after germination. Watering is reduced to once a day for weeks after germination.
CHOOSING A SITE FOR A VEGETABLE GARDEN
There are many factors to be considered when choosing a site for a vegetable garden. The following are some of them:
ª water supply
ª type of soil
ª nearness to home or school
ª nearness to market
LAND PREPARATION
Land preparation for leaf vegetable growing include:
TRANSPLANTING VEGETABLE SEEDLINGS
Most leaf vegetable seedlings are ready for transplanting in about 4 to 5 weeks after sowing. This is when most seedlings have reached recommended size or height of 10 to 15 centimetres.
Seedlings should be transplanted late in the afternoon on cool, cloudy or rainy day so that they do not wilt.
Seedlings are hardened-off before transplanting.
Hardening-off is done by reducing the frequency of watering seedlings to once per day for a period of 1 to 2 weeks before transplanting. The seedlings can be left without watering for the last 2 to 3 days before transplanting

IMPORTANCE OF RABBITS
BREEDS OF RABBITS
There are different breeds of rabbits. These are:
The recommended breeds in Malawi are New Zealand White and California.
These two breeds are able to adapt to different conditions and systems of keeping rabbits.
CHARACTERISTICS OF RABBIT BREEDS
UNIT 28 HOUSING AND FEEDING RABBITS HOUSING RABBITS
Rabbits need to be properly housed for increased production. A good rabbit house protects the rabbits from enemies such as dogs, cats and snakes. It also protects rabbits from bad weather.
There are different ways of housing rabbits such as:
It is made of poles and thatched with grass. The khola is raised 1m above the ground for hygienic reasons. This reduces infestation of maggots and worms. Rabbits are also unable to burrow the ground and hide. The floor or bottom of the khola should have holes big enough for droppings to fall through and small enough for young ones not to fall through. A wire mesh or flat mesh can be put on the floor if the floor has big spaces. This keeps the khola well ventilated and self cleaned.
Constructed using bricks or stones. The roof is thatched with grass or iron sheets. Make sure that there is enough space for each rabbit. Provide bedding materials such as wood shavings to a depth of 7.5 cm as litter. The deep litter khola should have clean and dry litter to prevent infestation of maggots.
Can be constructed using wood or bamboos. Hutches can be divided into individual cages. Hutches should be easily transportable if need be. Does, bucks and weaners have different cages. A cage for a buck is slightly larger than a doe's. This is to accommodate a buck and doe when placed in a buck's cage for mating.
Single hutch for a doe
Hutch for weaners
Single hutch for a buck
FEEDING RABBITS
Rabbits are easier to feed largely because of their small bodies. They can be fed on food which otherwise would be thrown away by a household. They are an example of animals that do not compete with humans for food, such that a farmer is unlikely to face the problems in supplying food to rabbits. Proper feeding is a key to successful rabbit production.
Rabbits kept in hatches and kholas are totally dependent on the keeper for the feed.
Rabbits prefer fresh feed materials such as carrots, potato vines, cabbage and ground haulms, elephant grass, banana leaves, mwanaaligone, Tridax (Kwakhwaniwa). Green grass should also be fed to rabbits daily in addition to other feeds. A balanced feed should be prepared or bought and fed to rabbits at all times.
THE FOLLOWING GUIDELINES CAN BE USED TO PREPARE FEED FOR RABBITS:
COMMON CONCENTRATE FEED STUFFS AND HOW TO MIX THEM
Group A sun flower cake or groundnut cake
Group B boiled and dried beans or cotton seed cake Group C maize, rice, sorghum or millet, (meal or bran) Group D dried cassava or dried sweet potatoes
HOW TO MIX
Grain products should be put in heavy feeding troughs which rabbits cannot trip over. Plant materials
such as grass can be hanged (suspended off the ground or floor) in the cage as rabbits do not eat spoiled feed
Over feeding should be avoided especially green feeds because they have plenty of water which will make the belly of rabbits to be filed with water resulting in low growth.
One way of noticing a hungry rabbit is that it comes to meet the farmer when approaching the khola.
WATER
Provide clean water to rabbits at all times.
A low supply of water will affect feed intake, growth and production of milk in rabbits. Water should be put in heavy containers so that they are not tripped over by rabbits. If rabbits are given large amounts large of dry feeds increase the supply of water.

MEANING OF AGROFORESTRY
The term "agroforestry" is formed by combining two original words of "agronomy" and "forestry". Therefore, the term "agroforestry" means the growing of arable crops together with trees on the same piece of land.
TYPES OF AGROFORESTY
Agroforestry is classified into three main types as follows:
Silvoarable
Mixing trees with arable or horticultural crops such as maize, sorghum, beans, cotton, groundnuts, cabbages, tomato and carrots.
Silvopasture
Mixing trees with pastures or grass for grazing livestock.
Forest farming
Cultivating high value products within the forested area:
Medicine, botanical decoratives, handcrafts, food as well.
SYSTEMS OF AGROFORESTRY
The following are some of the agroforestry systems practiced in Malawi:
Folder banks
This involves planting trees used as feed for livestock alternated with arable crops. The tree are frequently pruned to feed livestock.
Live fence
This involves planting trees and shrubs along the boundaries of arable crops.
Some of these trees may produce agroforestry products like fruits, timber and firewood.
Improved fallows
This involves growing legume trees on an arable land which is under fallow. This increases organic matter and improves soil structure and fertility.
Dispersed tree planting
This involves planting certain types of trees at random with arable crops.
Alley cropping
This involves planting rows of trees alternated with rows of arable crops.

RESPONSIBILITIES AND ROLES OF A JUDGE
THE STORY OF GIDEON (Judges Chapters 6, 7 and 8)
The Israelites had sinned against God and were serving punishment. Everything they had was taken away by the Midianites.
It was because of these reasons that the Lord appointed Gideon, the son of Joash from the clan of Mannasseh, to save Israel from the hands of the Midianites.
THE MISSION OF GIDEON
The mission of Gideon was to save Israel from the Midianites.
Gideon was with the Lord and he conquered Midian using only 300 men. This was a small number of soldiers compared to those of the Midianites.
God told Gideon to use a small number of soldiers to show God’s power.
THE STORY OF SAMSON (Judges Chapters 15 and 16)
God appointed Samson, the son of Manoah, to deliver the Israelites from the hands of the Philistines. During his life, Samson killed many Philistines.
As a Nazarite, Samson was not supposed to cut his hair because his strength was in the hair. Later, after several attempts, Samson revealed his secret to his wife Delilah.
The wife then told her people who sent her to cut his hair and Samson became weak. Afterwards, the Philistines gouged Samson's eyes out.
One day they took him to a building to entertain them. During entertainment, Samson prayed to God
He held two pillars of the building and pushed them.
The building fell down and killed everyone in the building including Samson.
THE MISSION OF SAMSON
The mission of Samson was to deliver Israel from the hands of the Philistines.
THE STORY OF DEBORAH (Judges Chapter 4) The Israelites had sinned again.

A parable is a story using everyday events to illustrate a religious or moral point.
WHY JESUS USED PARABLES IN HIS TEACHINGS
EXAMPLES OF PARABLES THAT JESUS USED
THE PARABLE OF THE GOOD SAMARITAN (Luke 10:25-37)
A lawyer tempted Jesus by asking him the following questions: What shall I do to inherit eternal life? Who is my neighbour?
Jesus answered him by telling him about the parable of a Good Samaritan.
Where a man was going down from Jerusalem to Jericho when he was attacked by robbers. They stripped him of his clothes, beat him and went away, leaving him half dead.
A priest passed by without helping him.
So too a Levite passed by on the other side without helping him.
But a Samaritan, when he saw a man he took pity on him, went to him and bandaged his wounds, pouring on oil and wine.
The Samaritan cared for the wounded man until he was fine.
THE LESSON LEARNT IN THE PARABLE OF THE GOOD SAMARITAN
THE PARABLE OF THE TWO SONS (Matthew 21:28-31)
In this parable, a father had two sons who asked them to do a work.
The first son refused to do what his father had asked him to do but later, he repented and did the work.
The second son accepted to do what the father had asked him but did not do it.
LESSON IN THE PARABLE OF THE TWO SONS
THE PARABLE OF THE PRODIGAL (LOST) SON (Luke 15:11-32)
The lost son realised his sinfulness and suffering. He decided to go back to his father for forgiveness.
On return his father welcomed him and celebrated by killing a fattened calf. The elder brother was angry with the father's decision
But the father persuaded him to forgive and accept his young brother.
THE LESSON IN THE PARABLE OF THE LOST SON
THE PARABLE OF THE LOST COIN (Luke 15:8-10)
In this parable a woman lost a coin and laboured to find it.
After she had found it, she rejoiced together with her friends and neighbours.
THE LESSON IN THE PARABLE OF THE LOST COIN
THE USE OF PARABLES IN MALAWIAN CULTURE
Parables are used in Malawian culture to tell stories about everyday life while giving a lesson beyond the story.
EXAMPLES OF PARABLES USED IN MALAWIAN CULTURE
"All that glitters is not gold" (chikomekome cha nkhuyu m'kati muli nyerere) means that it is not good to be attracted by the outward appearance of anything.
"Beauty is in the eyes of the beholder" (kanthu kali makonda buluzi anakonda khonde) "Prevention is better than cure" (kuteteza n'kwabwino kuposa kuchiza)
"Good things do not fill a spoon" (zokoma sizikuti leke)
THE USE OF PARABLES IN TEACHINGS OF JESUS (Luke 10:25-37; Matthew 21:28-31; Luke 15:11-32; Luke 8:4-21)
Jesus used parables to illustrate and convey meanings beyond the stories. These include the parables of the vineyard and people losing their coins. Jesus used such stories for easy understanding.

Personal space refers to that space within the reach of an individual
General space refers to the environment within which an individual operates It may be a small room, large field or cafeteria
Failure to understand personal or general space may result in hardships of some kind For example, limited personal space may lead to failure to perform an activity effectively Limited general space can lead to participants bumping into one another
There are four components of general space:
NB, Personal space is one’s area of influence or direct control. It is also called kinesphere
It depends on a number of factors such as size of the person and the type of activity being done
The term ‘artistic ‘refers to the creativity, beauty and excellence in doing an activity, be it physical or non- physical.
Movements occur always in everyday life.
Most of the daily activities that we do require body movements. For example; cooking and sweeping. Body movements may also occur in response to a stimulus.
The rhythm is a combination of different lengths of sounds and silences.
Examples of Rhythmic Activities in Everyday Life
Sounds and silences can be presented by symbols called musical notes. There are 5 commonly used notes:
it is oval in shape and has a white note head
it is made of a white head and a stem
it has a black head and a stem
it has a black head, a stem and a flag
it has a black head, a stem and two flags Sounds are also known as pitches.
Silences are also known as rest. Beat is also called pulse.
Musical notes have British and American names.
Rest signs and their names
A time signature is a set of two numbers at the beginning of a rhythm.
It is written as a fraction such as 6/8
The top number shows the number of beats or counts in a bar/measure.
The bottom number shows the name of the musical note that is getting one beat or count.
The most commonly used time signature is 4/4 because it is easy to understand and learn.
The notation of music consists of staffs, clefs, meter or time signature, key signatures and notes of various times which indicate the relative duration of pitches.
Musical notation, therefore, comprises a set of terms and symbols for musical meanings.
This refers to a set of five lines and four spaces on which musical symbols are written to give a melody or a song.
Sometimes when writing music you may need additional lines below or above the staff. Such lines are called ‘ledger lines’. They indicate pitches above or below a staff.
The five lines and four spaces have letter names which do not change. The letters are A B C D E F G.
These are symbols allocated at the beginning of the staff, on the left end. G clef or Treble clef identifies the second line from the bottom as line G. G or Treble clef staff is used for soprano and alto voices in choral music.
The ‘F’ clef or ‘Bass’ clef establishes the location of F in the fourth line of the staff. F clef staff is used for tenor and bass voices.
These are vertical lines on the staff which divide the staff into parts containing equal number of beats.
This is the space between bar lines and containing specified number of beats.
This is a distance that covers eight musical notes, with the first note being equal in tone to the eighth note, however, lower in pitch to the eighth.
These are the pitch names: DO RE MI FA SO LA TI DO
It means changing a piece of music from one key to another. For example, from C to F or G or vice versa.
There are various reasons for transposing a piece of music.
The following are some of the reasons:
This identifies which pitch is do
It is shown on the staff with sharps or flats.
Here are some examples of keys
This is the arrangement of notes usually of the same totality, either in ascending or descending order.
Two examples are:-
This includes eight pitches in major or minor scales. For example, do re mi fa so ra ti do
This includes only five pitches in major or minor scale (the fourth and seventh pitches are left out).
For example; do re mi so la do
The terms and signs are shown in the staffs as below:-
A dot takes half the value of any note or rest that it is attached to.
If the value of a quarter note is equal to 1 beat, then a dotted note is equal to 1 beat plus half one beat, so the total value is one and a half beats.
Examples
A beaming note is a line which is used to join two or more notes together.
The number of beams or lines one uses to join the notes will tell the number of flags each one of the joined note has.
For example:-
Rhythm patterns can be performed by:-
Mirroring is the act of copying actions, words, or expressions of another person
It is a commonly used technique in physical activities intended to demonstrate a physical movement: a new dance step, a lay-up in basketball, a tennis serve, including running activities.
Aerobics are physical exercises done following music Aerobics is a great medium to develop fitness
This involves a lot of jumping
This does not involve jumping, but always, one foot has contact with the floor
This uses stepping up and down from the platform
This uses kicks and punches
Aerobics is different from dance, because the aim of aerobics is to improve fitness while the aim of dance is to develop creativity.
NB. Aerobics is vigorous physical exercises done in order to increase the amount of oxygen taken into the body.
The different attire that people wear may have a meaning for the specific occasion or function.For example, in Malawi, the Ngoni are fond of wearing their traditional attire of animal skins and shields to symbolise that they are warriors.
During most weddings, the bride wears white attire to symbolise purity.
During funerals, widows usually wear black attire during the entire mourning period to symbolise sorrow.
During the biblical times, the kings and officials wore sackcloth when something went wrong or when calamity fell on the land.
Some sounds have cultural meanings.
These sounds can be those produced during certain functions and occasions which are understood by the people who share the same culture.
For example:-
Cultural values can be manifested in many different ways besides attire and dances. There are certain postures and movements which portray cultural meanings.
For example, when crossing with elders, most cultures recommend the younger one takes off the hat temporarily as a sign of respect.
There are also times when some people clap hands gently and softly when crossing with an elderly person.
Some postures and body movements are squatting or kneeling when receiving or giving items to the elders.
Malawi has many cultural dances that have cultural importance for every cultural setting.
Among the well-known dances are Gulewamkulu among the Chewa, Chioda among the Nkhonde, Vimbuza among the Tumbuka, Likwata among the Sena and Jiri among the Lomwe.

Artistic Activities from Various Cultures in Malawi
Multi-cultural performances are performances from different cultures.
Malawi has different ethnic groups like the Chewa, Ngoni, Tumbuka, Lomwe and Sena. Each of these ethnic groups has its own cultural performances.
These cultural performances have any aspects that are similar and different.
These aspects include the attire, instruments used in performances, organisation of cultural performances and the type of performances.
The cultural practices (performances) serve as an identity for a particular tribe or ethnic group. Malawi has different cultural practices.
These include folk dances and songs.
A folk dance is a recreational or ceremonial dance that is usually performed by members of the community.
For some tribe, a dance could be a form of a ritual.
They believe that a certain dance can make the rain fall, improve harvest and/or awaken the spirits of the dead.
In different performances such as in drama, dance or choir, performers wear appropriate attire to suit the performance.
Attire makes the performers look smart and coordinated.

Drama is acting out situations in order to inform, entertain and educate the audience.
When dramatising such plays, the actors and actresses should appear real. Firstly, this can be achieved through the use of visual aspects such as:-
Secondly, this can be achieved through sound effects such as:-
The purpose of this is to make the audience see and hear the play.
Most Malawian societies use musical instruments.
Some of the musical instruments are:
There are two main types of musical instruments
These are:
Tuned musical instruments such as the banjo produce different pitches
More examples of tuned instruments:
Untuned musical instruments such as chisekese produce a fixed pitch. More examples of untuned musical instruments:
Musical instruments can be sold and generate income.
However, the making of musical instruments can have a negative impact on the environment.
The excessive use of trees without replacing them can lead to deforestation, siltation in rivers and degradation of the land (land degradation).
Therefore there is need to replace the natural resources like trees to ensure sustainability of the resources.
Musical instruments can be played by:
The other group of musical instruments is called body percussion. Body percussion is the use of the body in various ways
The body can produce sound by:
Local dances are traditional dances that are performed in the communities.
Chilimika means year
This dance is performed mostly by young Tonga women of Nkhatabay District.
At each New Year's Day, young men and women congregate at the village arena to entertain the village with Chilimika.
This dance is an imitation of Malipenga which is mostly performed by men.
Gulewamkulu is also known as "the Great Dance".
Gulewamkulu is performed at the request of the village headman on the occasion of funerals of village members, puberty initiations and the installation of chiefs.
It is performed by Chewa men.
Likhuba is a dance performed to cure psychological illness by women.
It is largely an acrobatic demonstration of male prowess by the Sena of Lower Shire. These days the dance is performed for entertainment.
Tchopa or Soopa was originally performed by the Lomwe during tribal wars as well as sacrificial ceremonies when a calamity had struck.
Tchopa is popular in Thyolo, Mulanje and Chiradzulu Districts. It is mostly performed for entertainment.
Uyeni is a Ngoni dance usually for girls who dance bare foot with their breasts exposed. It is mostly performed during the installation of chiefs.
In the Chisukwa dialect, the word mwinoghe literally means "let us enjoy ourselves thoroughly". Mwinoghe is an instrumental dance that is popular among people especially school children in Chitipa District of the Northern Region of Malawi.
It has been derived from a ceremonial dance of Karonga District called Indingala which was originally performed by men brandishing fly-whisks during either the enthrallment of a chief or feast over a dead marauding lion.
The main percussion instruments used in the dance are one big drum called Ing'ina and two small ones called Twana, but sometimes a whistle is used.
The dancers line up in two straight lines, boys on one side and an equal number of girls on the other, facing one another. While the girls continue dancing in a standing position with their hands raised up, the boys squat down wriggling and twisting their bodies, all to the rhythm of the instruments.
Mwinoghe is therefore a cerebration dance
Manganje is an initiation dance performed by the Yao of Machinga, Mangochi, Zomba and Blantyre Districts.
It is performed at the initiation of boys.
Today Manganje is also performed for entertainment.
Malipenga is a modern dance for men.
Malipenga started in Nkhatabay District and spread all over the Northern Region of Malawi.
In the central region, Mganda, which is a variant of Malipenga is performed in Kasungu, Nkhotakota, Salima, Ntchisi, Dowa and Lilongwe Districts.
Most of the Malawian traditional dances have cultural values and a history.
However, most of Malawians, particularly the youth, do not participate in these cultural dances.
Some dances that depict cultural values are as follows:
Malawi is also flooded with a lot of contemporary dances.
However, traditional dancing styles can be combined with contemporary dancing styles to improve the performance.
The disadvantages of mixing traditional dancing styles with contemporary dancing styles are that:
These foreign dancing styles have influenced the way people perform the local dances.
The people combine the foreign dancing styles with the original styles with the original styles to improve their performance.
Posters on Various Themes
Posters are useful in the dissemination of information on a cross-cutting issues
Cross-cutting issues are challenges that affect many people and cause great concerns
The school can perform dances where songs contain messages on issues concerned.
The dances and songs are a form of entertainment to draw people’s attention as they listen to messages.
Songs, like dances, play an important role in conveying messages on cross- cutting issues
Singing and dancing together offer entertainment to motivate the target audience while receiving messages by passed on
The messages on cross-cutting issues are easily passed on to an audience through plays.
A play is a form entertainment intended to attract the attention of the audience while the messages are passed on.
Some of the themes can be on:
Most of the activities that we do require movements These movements require skills
A skill is a talent that an individual shows when doing something. Most of the skills that individuals have are either learned or inborn. There are various artistic activities that are popular these days These are known as contemporary artistic activities
The common examples of artistic activities are songs and dances.
Various materials found in the local environment can be used for artistic activities
Every individual has skills that are either acquired or inborn.
Possessing these skills is very important because individuals that possess them often become successful in whatever they do.
The production of posters, carvings, models, woven items and knitted items require these skills.
Posters on Various Themes
Posters are useful in the dissemination of information on a cross-cutting issues
Abstract carving does not have a definite form
It can be interpreted differently by different people
Stylish carving has a definite form
However, some parts are exaggerated deliberately
For example, a carving of a person with a protruding chin
Naturalistic carving has a form which looks definite or real
Materials for Modelling Various Items
Weaving is the interlocking of warps and wefts.
The warp is the set of strands which are laid across the loom at the beginning of weaving.
The weft is the pattern of strands woven in and out of the warp.
This interlocking follows a given pattern of:
Row 1: Over 1 under 1 over 1 under 1 – continue
Row 2: Under 1 over 1 under 1 over 1 – continue After line B repeat from line A to form a check weave.
Row 1: under 1 over 2 under 2 over 2 under 2
Row 2: over 2 under 2 over 2 under 2 over 2
Row 3: over 1 under 2 over 2 under 2 under 2
Row 4: under 2 over 2 under 2 over 2 under 2
After row 4, continue by repeating row 1. This produces a twilled or diagonal weave.
Materials for Knitting Various Artistic Items
There are two basic knitting stitches:
All patterns are formed based on variations of these two stitches
This stitch can be used in making knitted belt, scarfs or baby blankets
This stitch is often used to knit stockings and pencil bags
This stitch is a combination of knit and purl stitches done in the same row
This stitch forms the border of many knitted garments’ edges such as the sleeves, necklines and the edges

Good and quality musical sound is a result of good voice production.
Good voice production comes through practice of a number of musical related exercise. There are many activities we can do continuously to develop good voice production Some of the exercises that one can do are as follows:
- This involves control of jaws rather than the lips alone.
Diction is the articulation of words clearly
When singing one conveys a message. Therefore, there is need to say the words clearly so that the message is clear.
Recording a song can be done at:
Recording a song should be done in an appropriate place or room that is free from noise and wind
Record the song several times to get the right quality that is required
Step 1 Think about the message you want to convey in the songs Step 2 Identify the target audience
Step 3 What mood of the song do you want to convey your message through? Step 4 Identify a tune for your song
Step 5 Find words to the tune of your song (consider things such a rhymes in your words of the time, just like in poetry)
Composing instrumental music involves musical instrument without words. This can be done by playing one instrument or many instruments combined.
The most important factor to consider for instrumental music is to create room for each instrument to be heard clearly.
There has to be times where one instrument is played louder than the rest.
One can also use handclapping, tongue, clicking, finger snapping as musical instruments besides the drums and other musical instruments.
However avoid overcrowding the song with instruments.
A skill can be defined as a way to do something
When writing plays for the public performance the playwright should consider the audience first. The target audience will determine the theme and characters to be in the play.
For example, if one is writing for the school going youth, the basic idea should suit the age and type of students.
Likewise when one is writing for the community, one should have a picture of what kind of community it is, what are its likes and dislikes, what are the people’s beliefs and educational levels
Therefore, factors to consider when writing a play for public performance are:
® Target audience
® People’s beliefs
® Educational levels
® Likes
® Dislikes
® Cultural background
® Age
Whatever audience you are writing for, ensure that there is a theme (the basic idea you want to pass), a realistic plot (story line) and characters (people in the play).
When acting out, make sure you create a conflict.
The audience should be kept in suspense up to the end, but towards the end the audience should see the climax and get resolutions of the climax.
A climax is the point of the story at which the interest is highest.
This comes somewhere near the end and after this there are resolutions.
Drawing is a means of expressing and communicating one’s feelings. Drawing is an arrangement or organisation of lines to make basic shapes. The drawings may be two dimensional or three dimensional.
Some of these may be traced using paper, transparent plastic sheets and perforated picture outlines.
Three dimensional drawings can be formed by shading the two dimensional drawings. Shading makes them look solid.
Drawings or pictures for sale should look attractive.
In order to achieve this, painting or colouring is done to add beauty. After colouring, the items can be given costs, advertised and sold.
® It helps to increase sales
® It helps producers to know their competitors and plan accordingly to meet up the level of competition
® It helps in making people aware of the new product
® It helps creating goodwill for the company and gains customer loyalty after reaching a mature age
® It helps educating people
® It helps people find the best products for themselves
Activities such as making the costumes and drama performances can be a source of income.
The production of costumes for various activities requires the identification of suitable materials, taking of appropriate body measurements and cutting out of suitable patterns.
Body measurements can be taken from:
Measure at your waist under the hip bone
Start at the hip level on one side, then capture the middle of the groin before wrapping around the opposite side
Wrap the tape high under the armpits around to the front of the chest
Measure at the highest point of the thigh, under the pubic bone
Measure at the thickest point of the calf, typically half way between the knee and the ankle
Wrap the tape measure around the biceps half way between the armpit and the fold of the elbow
Measure the shoulder line from the back
Expression and communication can be done in various ways.
It can be done through speaking, writing, gestures and artefacts.
The communication without speaking is called non-verbal communication.
Different items can be done in different ways.
The following are tools for hunting:-
Some of the hunting tools are made by carving. For example, clubs
The following are methods of decorating hunting tools:-
Clay work, like pots and flower pot holders can be decorated by:-
Different body movements can convey specific messages.
For example. A person might use a wave rather than saying “hello”. Or nod their head in agreement, which may mean “yes”.
The body movements can be useful in expression and communication because they are a quick way to convey thoughts and feelings without speaking or writing.
The identification of the messages to be expressed and communicated by the body movements is important in every social setting.
This is so because it enhances cooperation and a caring spirit among the members of the community.
Drawing is a means of expression and communication which uses visual images to pass on information to the reader.
The drawings can contain a lot of information as much as writing. Pictures convey messages quicker than writing.
Items to Meet Personal and Community Needs
Different people need different items in their lives.
Some of the items can be purchased from shops while others can be made.
Producing your own items can help you to cut down the costs which you could have made in the course of purchasing the items (save money)
On the other hand, producing items to meet other people’s needs becomes a source of income to the producer.
Some of the items that one can make are garments, household items and safety equipment.
Plaiting is weaving strands of hair, rope and so forth together to make a plait. Plaiting is the interlocking of three or more strands.
Three strands can be used for making ropes for table mats or tying goats and mesh for hair. More strands can be used for making mats.

Latitudes are imaginary lines which run horizontally across the earth's surface.
Longitudes are vertical lines measured at an angular distance east or west of the prime meridian.
MAJOR LATITUDES AND LONGITUDES
The earth is round like a ball.
It is covered by imaginary lines evenly-spaced and running vertically and horizontally. These lines are called latitudes and longitudes.
Latitudes and longitudes are measured in degrees.
MAJOR LATITUDES
The most important lines of latitudes are
MAJOR LONGITUDES
The prime meridian is one of the important longitudes The prime meridian is also called the Greenwich meridian Longitudes are also known as meridians
They meet at the poles
IMPORTANCE OF LATITUDES AND LONGITUDES
Places east of any longitudes see the sun earlier than those west of the longitudes
Slave trade is buying and selling of people.

GROUPS OF PEOPLE INVOLVED IN THE EAST AND CENTRAL AFRICAN SLAVE TRADE
WHY DID CENTRAL AFRICA GET INVOLVED IN THE SLAVE TRADE
METHODS OF OBTAINING SLAVES
THE EFFECTS OF THE EAST AND CENTRAL AFRICAN SLAVE TRADE
THE ABOLITION OF THE SLAVE TRADE
The British Government made several attempts from the 19th Century to persuade the Sultan of Oman to limit slave trading activities, and finally, put a stop to it.
In 1873, the British Government successfully persuaded Sultan Burghash of Zanzibar to stop the slave trade. Consequently, the Zanzibar slave market, the biggest in East Africa, was closed down.
In Malawi, the slave trade stopped because of the efforts that Sir Harry Johnston made. He made a treaty with Jumbe III to give up his slave trading activities in return for payment equivalent to K200 per annum. In the south and north of Malawi, the British Government had to fight with the Yao chiefs and Mlozi respectively.
In Zambia, the British Government made a treaty with Lewanika of the Lozi in 1897 to stop the giving of slaves as a tribute to the chiefs, and to stop slave raiding. In 1906, domestic slavery was abolished and this marked the end of slave trade there.
There were several missionaries who came to Malawi. These include:
THE WORK OF EARLY MISSIONARIES IN MALAWI
The Universities Mission to Central Africa came to Malawi to answer the call made by Dr David Livingstone.
REASONS WHY THE UMCA came to Malawi
The UMCA was established under the leadership of Bishop Mackenzie in 1861. Its first mission was established at Magomero in Chiradzulu.
Magomero was chosen because it was one of the centres where there were a lot of slave trading activities.
In 1863, the mission moved to Zanzibar in Tanzania under the leadership of Bishop Tozer. This was because the missionaries were attacked by malaria and unfriendly Yao traders.
Later, in 1885, the UMCA returned to Nyasaland and opened the mission station at Likoma. OTHER MISSION STATIONS OF THE UMCA
A map of Malawi showing the location of the UMCA mission stations
The Scottish Missionaries of the Church of Scotland and the Free Church of Scotland came to Malawi through the influence of Dr David Livingstone's work.
The Scottish Missionaries originated from Scotland.
The missions were in two groups and established their stations in Blantyre and Livingstonia
BLANTYRE MISSION
The Blantyre Mission was established in Kapeni's area in 1876 by the Church of Scotland. The first leader was Henry Henderson.
The area was chosen because:
Henry Henderson was succeeded by Reverend Duff Macdonald, David Clement Scott and Alexander Hetherwick
THE LIVINGSTONIA MISSION
The Livingstonia Mission was established by the Free Church of Scotland in 1875 in Cape Maclear as the first mission station.
The first leaders were Captain Edward Young, James Stewart and Dr Robert Laws.
Cape Maclear was chosen because of the good harbour for the Illala I which was taken as a ship for the mission.
Robert Laws succeeded Edward Young and moved the mission to Bandawe in Nkhatabay in 1881. The Cape Maclear mission station was moved to Bandawe mission station because
Bandawe was chosen because of the following reasons
The station was later moved from Bandawe to Khondowe, now known as Livingstonia, in 1882 because of the following reasons
Blantyre and Livingstonia Missions were established in honour of Dr David Livingstone and they belong to the Church of Central African Presbyterian (CCAP)
Blantyre Mission Stations

Another group which was influenced by Robert Moffatt and Dr David Livingstone's work was from South Africa.
This was the Dutch Reformed Church. This group came to Malawi in 1888 under the leadership of Reverend Andrew C Murray.
In 1889, Reverend Teunis C Botha Vlok joined him. The two set their first station at Mvera in Dowa district.
In 1895, Reverend William Hope Murray succeeded Reverend Andrew Murray. He led the mission until his return to South Africa in 1937.
The mission station was moved from Mvera to Nkhoma in 1910 because of the following reasons
A map of Malawi showing the location of the DRCM mission stations
OTHER DRCM MISSION STATIONS
All these stations are under the Nkhoma Synod of the CCAP.
Another group which had some influence of Dr David Livingstone's work were the Catholic Missions. These were in three groups.
This was the first Roman Catholic Mission to come to Malawi. It began its work in 1889 by three priests.
These went to Chief Mponda in Mangochi. Their leader was Father Lechaptois, a Frenchman.
They later abandoned the place and went to Zambia in 1891 because Chief Mponda was a Moslem, a slave raider and was against Christianity.
The other team led by Father Guilleme came back from Zambia in 1901 and established a station at Chiwamba in Lilongwe. The mission was later moved to Likuni in 1903 because there were more people in Likuni.
Other white fathers arrived on the lakeshore and established a station at Mua in Dedza where a leprosarium was started in 1927.
This group came to Malawi in 1902. They established their first station and school at Nzama in Ntcheu. In 1903, they established another centre at Nguludi in Chiradzulu.
OTHER MISSION STATIONS WHICH WERE ESTABLISHED
The White Sisters came to Malawi in 1911. These were followed by the Grey Nuns.
In 1932, a printing press was set up at Bembeke but was later transferred to Likuni in 1949. In 1940, the missionary work expanded to the northern region.

The Independent African Churches were established by Africans.
These were developed as a result of the work of the UMCA, Scottish Missions, the DRCM and the Roman Catholic Missions.
REASONS WHY THE INDEPENDENT CHURCHES STARTED

Islam was brought to Malawi by Arab Swahili traders. The Arabs came from Arabia and the Persian Gulf.
The Arab Swahilis came to Malawi because of trade.
The notable Arab Swahili traders were Mlozi and Msalemu at Karonga and Jumbe Salim bin Abdullah in Nkhotakota.
In the southern region, there was no any well-known Arab Swahili trader but Islam spread among the Yao because of the following reasons:

UNIT 5 WORK AND MONEY WORK
Work is any activity which a person does to earn a living
Examples of activities one can do to earn some money are:
There are two main types of work. These are paid work and voluntary work.
PAID WORK
This is when people work to get money for a living.
Examples of paid work
VOLUNTARY WORK
This is when people work or provide services without getting any money.
Examples of voluntary work
THE IMPORTANCE OF WORK
MONEY
Money are stamped coins or printed notes given and accepted when buying and selling.
TYPES OF MONEY
There are three types of money.
These are:
Coins are stamped metals made of gold, copper or silver.
Bank notes are paper money sometimes called paper currency.
Bank notes are in a form of cheques, credits, postal orders, money orders, traveller's cheques and bank drafts.
The safest way of keeping money is in banks.
FUNCTIONS OF MONEY
FIRM, COMPANY and INDUSTRY
Businesses can be classified into a firm, company or industry.
People earn a living in different ways.
Some of the ways are through employment as they work for another organisation or self-employment.
In self-employment, one can decide to start a business such as owning a hawker, family farm or an organisation which can employ many people.
When a person employs many people in an organisation, it is called a firm. A firm usually has a limited capital.
When business expands, the person running it may not manage it alone. Some suitable people may join to form a partnership.
The new people who join and put in some money or buy shares are called shareholders. In return for putting money into the business, the partners share the profits.
The partners assist the business in many ways.
Some of the ways are providing new ideas for improving sales and management. The shareholders do not usually work on their own.
They set up a board of directors and employ people to run the business. This is now called a company.
When a company grows and makes a lot of profits and is recognised by many countries, it becomes an industry.
In an industry, raw materials are changed into finished products.
There are three types/categories of industries. These are:
Primary Industry
@ This involves the exploitation of natural resources and raw materials.
@ It includes agriculture, forest, fishing and mining.
Secondary Industry
@ This deals with the manufacturing of products.
@ This can be directly from raw materials or from other materials from other sources.
Tertiary Industry
@ This consists of jobs that provide services but do not actually produce any goods.
Examples of these include a wide range of businesses and professionals such as health, education, armed forces, government offices and management in private industries.
It also include people involved in transport and retail trades.
THE RELATIONSHIP BETWEEN DEMAND AND SUPPLY IN RELATION TO PRICES
Demand is the number of people who will require the goods and services. Supply is amount of something that is provided or available to be used.
Factors That Affect Demand and Supply
On the other hand, supply is affected by the following:
When demand is high, companies and industries produce more.
When there are a lot of goods on the market, supply is high and the price is low. When there is a high demand and the goods are in low supply, the price is high.
A company is a commercial business.
A company is a legal entity formed by a group of individuals to engage in and operate a business enterprise.
An industry is an economic activity concerned with the processing of raw materials and manufacture of goods in factories.
An industry is a group of manufacturers or businesses that produce a particular kind of goods or services.
CLIMATE
Climate is the average weather conditions observed over a long period of time.
It is mainly composed of rainfall and temperature. Climate can either be hot or cold, wet or dry.
Africa can be divided into a number of climate zones.
These are controlled by a number of factors such as altitude, distance from the sea and distance from the equator.
THE MAJOR TYPES OF CLIMATE OF AFRICA (MAJOR CLIMATE ZONES) AND THEIR CHARACTERISTICS
It is found between 50 north and 50 south of the equator. It has high temperatures.
Rainfall almost throughout the year.
It is found in countries like Ghana, Nigeria and Congo.
Its summers are usually hot and wet while the winters are generally cold and dry. It is found in countries such as Malawi, Tanzania and Zimbabwe.
It is experienced in North Africa in the Sahara Desert.
Desert areas are very hot during the day and very cold during the night. They receive little or no rain.
It occurs between 300 south and 450 south and 300 north and 450 north of the equator. The areas have dry summers and wet winters.
During the summer, it is dry and the skies are blue.
In winter, the skies are very cloudy and humid, bring heavy rainfall.
A map of Africa showing climate zones and types of vegetation
THE VEGETATION OF AFRICA AND ITS CHARACTERISTICS
The type of vegetation in an area is determined by the type of climate it experiences. For example, in Malawi, there is a lot of vegetation during the rainy season while during the dry season the vegetation dries up.
The following are some of the types and characteristics of vegetation in Africa.
The vegetation is found in areas along the equator. It is characterised by the following:
This is the type of vegetation that is mainly composed of grass. It is found in many countries in Africa.
There are several countries in Africa with this type of vegetation. This vegetation is found in both north (Sahara) and south (Kalahari) of the equator.
The following are the characteristics:
This vegetation is found in areas that experience the Mediterranean climate. It is found in South Africa and countries along the Mediterranean Sea.
The vegetation is shiny and waxy to conserve water during the dry season. Crops grown include dates, palms, wheat, maize and fruits.
CIVILISATION
The term 'civilisation' refers to changes and developments in life.
It can also refer to the organisation of society where people live a settled life together, and engage in activities such as formal education, trade, farming, building, fishing and painting.
The changes and developments include the following:
THE EGYPTIAN CIVILISATION
One of the most well-known civilisations in Africa was in Egypt. This civilisation grew along the Nile River Valley. Its achievements influenced a number of other civilisations in Europe and the rest of the world.
A map of ancient Egypt showing the centres of the early civilisation
FACTORS THAT LED TO THE GROWTH OF THE EGYPTIAN CIVILISATION
CONTRIBUTIONS OF THE EGYPTIAN CIVILISATION TO THE MODERN WORLD
WRITING
The Egyptians discovered a method of writing called hieroglyphics.
They wrote it on a material made from papyrus reed. It was a system of picture writing, in which a set of pictures represented a word or a sound. This discovery helped to improve communication and preservation of history.
CALENDAR
The Egyptians inverted the calendar based on the moon. The calendar enabled them to tell when to expect floods and when the dry season would start.
FARMING
The Egyptians practiced irrigation. They used a machine called a shaduf to irrigate their gardens.
a shaduf
BUILDING
The Egyptians were good stone builders. They used stone to build the temples and tombs. They built pyramids which were tombs for royal people like kings.
RELIGION
The Egyptians believed in many gods. These gods symbolised natural features like the sun, the moon and the Nile River. The Pharaohs were also believed to represent the gods on earth.
GOVERNMENT
The Egyptians were the first people to have a system of organised government. Their rulers were called the Pharaohs.
MEDICINE AND SCIENCE
The Egyptians manufactured and used many medicines. They developed a way of preserving dead bodies. The preserved bodies were known as mummies.
ARTS AND CRAFTS
The Egyptians were good stone and wood carvers. They made beautiful cloth from wool and cotton. They also made tools out of metal. When they discovered copper, they mixed it with tin to make bronze.
FACTORS THAT LED TO THE DECLINE OF THE EGYPTIAN CIVILISATION
GOVERNMENT
Government is an organised institution with people who are entrusted with the authority or power to administer the laws and affairs of a country.
BRANCHES OF GOVERNMENT
DIFFERENT TYPES OR SYSTEMS OF GOVERNMENT
DEMOCRACY
In a democratic system of government, no one individual, group of individuals or organisation holds absolute power.
It is based on the principle of participation and respect of human rights. All citizens participate actively in running the government.
This is why it is called the government of the people, by the people and for the people.
A democratic government is also characterised by the period elected members are in office. In Malawi it is 5 years.
AUTOCRACY (DICTATORSHIP)
This is a form of government where the power is in the hands of an individual or groups of individuals. The power is unchangeable. In most cases, the rulers are worshipped.
What the ruler has said is the law. Elections are irregular, not free and fair.
Candidates are either appointed or elected to participate in running the affairs of the government. The constitution is either absent or not followed.
MONARCHY
The rulers in this type of government are not elected.
They acquire their positions through inheritance by blood and they rule for life. Titles such as king, queen, emperor, empress and prince are used.
Sometimes monarchies have constitutional powers where rulers are guided by the constitution. In some cases, monarchs have absolute power in which their authority is not questions.
SOCIALIST OR COMMUNIST GOVERNMENT
This system of government is based on the economic and political beliefs that control the means of production, distribution and exchange of wealth in a country.
All the wealth in the country is controlled by the state. No one owns private property. Although rulers are elected, they come from one political party.
MILITARY GOVERNMENT
This is when a country is ruled by soldiers whose power is unopposed. Rulers assume power by force and are not elected.
Sometimes there is a parliament which just approves the orders of the military. There is no specific term of office.
THE HISTORY OF THE SYSTEMS OF GOVERNMENT IN MALAWI
Malawi has undergone changes in forms of government. In 1963, Malawi attained self government from Britain.
In 1964, Malawi became a multiparty republic. The leader was called the prime minister. In 1966, Malawi became a republic and the prime minister was now called the president.
Between 1971 and 1994, Malawi was a one party state under the Malawi Congress Party (MCP). Elections were held just for formality. The president became a life president, but the members of parliament changed during elections.
In some cases, the same people maintained their positions for as long as they were alive. Most leaders were imposed on the people and the constitution was silent and not followed.
With the one-party system, the ruler was a dictator and his word was law.
On 14 June, 1993, a national referendum was held to vote for either one party system of government to continue or to change to multiparty system of government.
Malawians voted for multiparty system of government. This saw Malawi reverting to a multiparty state.
On 17 May, 1994, general elections were held. There were a lot of political parties which participated in the elections.
Some of the political parties that took part in the general elections were:
Malawians elected United Democratic Front with Bakili Muluzi as president. A new constitution was written which followed the principles of democracy.
The central government is the part of government which controls the affairs of the country.
THE ORGANISATION STRUCTURE OF THE CENTRAL GOVERNMENT
Malawi has a two-level system of government:
THREE BRANCHES OF CENTRAL GOVERNMENT
THE COMPOSITION OF BRANCHES OF THE CENTRAL GOVERNMENT
The executive branch comprises of the president and the cabinet.
THE FUNCTIONS OF THE EXECUTIVE BRANCH
The legislative branch is composed of the speaker and members of parliament or national assembly. The speaker is the leader of the national assembly.
Members of parliament are elected into parliament through national general elections
Members of parliament represent people in parliament for their areas which are called constituencies. Members of parliament are elected for a period of 5 years.
THE FUNCTIONS OF THE LEGISLATIVE BRANCH
The judiciary is composed of the law courts, the chief justice, judges, registrar of the high court and the magistrate.
Each of these branch has powers to check on the other branches of Government therefore. They are all at the same level.
FUNCTIONS OF THE JUDICIAL BRANCH
TYPES OF COURTS
There three types of courts. These are:
HOW LAWS ARE MADE STAGES OF MAKING THE LAWS
The making of laws is one of the most important functions of parliament. The following stages are followed:
Stage 1: Members of parliament move a motion for a new law to be made or for a law to be changed. The proposal or draft document is called a bill. The Member of Parliament explains what the bill is about and gives the reasons for the new law or why the existing law must be changed. A bill is a draft document or proposal for a new law to be made or for a law to be changed
Stage 2: Members of parliament debate the bill for or against the proposal
Stage 3: Members of parliament vote whether to accept or reject the bill. It is passed once the majority of members of parliament
Stage 4: The bill is then presented to the president for approval. Once it has been approved, it becomes an act or law.
THE IMPORTANCE OF LAWS
HOW LAWS ARE ENFORCED
DEMOCRACY
The word ‘democracy’ comes from two Greek words demos which means people and kratos which means authority or power.
A democratic government is defined as a government of the people, by the people and for the people. Leaders are chosen by the people to represent them and protect their rights and interests.
A democratic government is characterised by the following principles:
PRINCIPLES OF A DEMOCRATIC GOVERNMENT
Regular, free and fair elections
There should be no intimidation or bribery or threats during elections.
Tolerance
In a democracy, people with different views must accommodate and respect each other despite the differences they may have.
The rule of law
In a democracy, no one is above the law. Everyone irrespective of status is equal before the law.
Control of abuse of power
This principles prevents elected leaders or appointed groups of people from abusing their power.
Bills of rights
This is a list of rights and freedoms granted to all the people, and limits the power of the government. The bill of rights is found in the constitution of the Republic of Malawi.
Equality
All citizens in a democracy should be treated equally regardless of their ethnic group, race, region, sex or political affiliation. Everyone should be valued equally and must have equal opportunities.
Citizen participation
Citizens must take part in the affairs of the government. This can be through voting, standing for elections, paying taxes, accessing information and participating in development work in their communities. People should also be informed by the government on the affairs concerning them.
Acceptance of election results
Accepting election results strengthens democracy. The losers should accept defeat.
Accountability and transparency
The leaders should be accountable to the people. They are answerable to people on whatever they have done. They should accept responsibility for their actions, and this should be carried in accordance with the people's will and interests. They should explain matters to the people and should be free to ask questions and get answers from their leaders.
SEPARATION OF POWERS
There are three branches of government in any democratic government. These are the legislature, the executive and the judiciary.
These branches clearly spell out separation of powers. These are there to provide checks and balances.
The head of this branch is the president. He or she is assisted by ministers and all civil servants. The duty of the cabinet ministers is to supervise the work of the government departments and help in making decisions on government policies. The ministers are given specific duties to do such as overseeing labour, education, health, agriculture and finance. Civil servants work under particular ministries.
This consists of the national assembly which together with the president make up parliament. This is the body which makes laws. The national assembly is composed of members of parliaments (MPs) who are elected once in 5 years to represent constituencies.
Constituencies are areas found in each district. The sizes and boundaries are decided by the electoral commission which is responsible for conducting all the elections. Any Malawian citizen of over 21 years can be elected to the national assembly.
The head of legislature is the speaker.
The speaker of the national assembly is chosen by members of parliament among the parliamentarians.
The speaker of the national assembly is responsible for chairing meetings and maintaining discipline in the national assembly.
The legislature or parliament is responsible for:
The national assembly also works through committees made up of MPs such as the public appointments committee, the finance and budget committee, the legal affairs committee and the education committee.
'Judiciary ' simply means the courts. Unlike the legislature and executive, the judiciary is an independent body. This branch represents an institution of government which exercises power through monitoring, checking and balancing the activities of the other two branches by requiring them to comply with the law at all times.
The judiciary in Malawi is made up of judges of the supreme court of Malawi, the high court and judges of smaller courts called magistrates.
These are the three levels courts in Malawi. All the courts are independent, which means they follow the law. No one is supposed to tell the courts how they should decide on a case.
THE FUNCTIONS OF THE COURTS
The judiciary is headed by the chief justice of Malawi appointed by the president.

POPULATION
Population is the number people found in an area.
THE POPULATION COMPOSITION OF AFRICA
Africa has many countries each with different population sizes. Each country is composed of different tribes each with its unique characteristics.
Each of the tribes belongs to a major group of people.
THE POPULATION DISTRIBUTION IN AFRICA
The population of Africa is not evenly distributed. Some countries have more people than others.

LOCATION OF THE MAJOR GROUPS OF PEOPLE OF AFRICA
The Hamites
The Hamites are generally found in the Nile Valley and Ethiopian highlands. They are believed to have originated from Arabia.
Some Hamites also moved south to Kenya and Tanzania.
The Nilotes
The Nilotes are mostly found in East Africa, in Kenya, Sudan and Uganda. They are believed to have originated from Egypt.
The Nilotes of Uganda are called the Acholi.
The Nilotes of Kenya are called the Luo. The Nilotes of Sudan are called the Dinka.
The Negroes
The Negroes migrated from Asia to Niger around Lake Chad and spread further southwards across the southern part of Sahara Desert in West Africa.
The Bantu
The Bantu came from the highlands of Cameroon (around Lake Chad).
They migrated southwards to the Democratic Republic of Congo from where they migrated further to most of the countries of North East, Central and Southern Africa.
The population of any place changes from time to time.
In most cases, the population increases. This is called population growth.
In some countries, the population may decrease. This is called population decline.

There were several explorers who came to Africa. Some of them are:
DR DAVID LIVINGSTONE
Dr David Livingstone was born in Blantyre, a small industrial town near Glasgow, Scotland in 1813. Livingstone started his life in Africa as a missionary and through his experience he extended his vision and enlarged his ambition to explorations.
He explored the Zambezi River and had the first view of the great falls of Mosi-O-Tunya which he later named after Victoria.
Thus, Livingstone is believed to be the first white man to reach Victoria Falls.
In May 1858, Livingstone reached the mouth of the Zambezi but his hopes were dashed when the Kebrabasa Rapids proved insuperable. He turned aside to Shire where his expedition was more fortunate and his steam boat sailed up and down as far as the cataracts named by Livingstone, the Murchison Falls.
On April 18, 1859, Livingstone saw Lake Chilwa for the first time and commented on the beauty of the Shire Highlands landscape.
On a third trip up the river in June, he reached Lake Nyasa itself. He noticed that there was abundant evidence of slave trade and the lake itself clearly provided one of the great trade routes in land.
At a village on the Lualaba River, he witnessed slaughter of villagers by slave traders. The letter he sent home describing the event infuriated the public, and English Government pressurised the Sultan of Zanzibar to stop the slave trade. The pressure was only partially successful as the trans-Atlantic slave trade organised by the Portuguese had begun around 1530.
Livingstone was another explorer fascinated by the problem of the source of the Nile as another explorer Speke claimed. He therefore, in 1866, set out on a journey whose aim was to clear up once and for all the mystery surrounding the source of the Nile. He set off from Zanzibar for Ujiji on the Lake Tanganyika.
He explored the region around the lake but his efforts to prove that Lake Victoria was the source of the Nile were fruitless. He did, however, discover Lake Bangwelu and explored the upper reaches of the River Congo before his death in 1873.
His two African assistants dried his body and carried it and his papers on a dangerous 11 mouth journey to Zanzibar – a trip of 1,000 miles. The natives buried his heart in Africa as he had requested, but his body was returned to England and burned at Westminster Abbey.
MUNGO PARK
Mungo Park was born in 1771 near Selkirk in Scotland. He was a surgeon and explorer.
In 1795, he was sent by the Association for the Promoting of the Discovery of the Interior of Africa to discover the course of River Niger as it was believed that the Niger was a tributary of either the River Senegal or Gambia.
He was regarded as the first of the famous North Western explorers. He explored the area bordered by the rivers of Gambia and Senegal. He reached the source of Niger River before turning back. He found out that Niger flowed east.
Mungo Park was accompanied by an ex-slave raider, Johnson, who had returned from the West Indies. He was also accompanied by a slave called Demba, who had been promised his freedom on completion of the journey.
At his first stop at Bondou, Park was forced to give up his umbrella and his best blue coat. Shortly after his encounter with the local Muslims, Park was taken as prisoner. Demba was taken away and sold. Johnson was considered too old to be of value.
After four months, Johnson and Park finally managed to escape. He had no belongings except his mat and compass but refused to give up the expedition even when Johnson refused to travel to travel further.
Relying on the kindness of African villagers, Park continued on his way to the Niger, reaching the river on 20 July, 1796.
In 1805, Park reached another agreement with banks. Park was to lead an expedition to follow the Niger to its end. His party consisted of 30 soldiers from the Royal African Corps plus officers including his brother- in-law, Alexander Anderson, who agreed to join the trip.
Against logic and advice, Mungo Park set off from the Gambia in the rainy season. Within 10 days, his men were suffering from dysentery. This led to the death of some members.
By November 19, 1805, only five of them remained alive. Park, lieutenant Martyn and the three soldiers. These set off downstream from Segu in a canoe.
At Busa Rapids, Park and his small party were mistaken the Muslim raiders and they were shot dead and drowned in 1806.
BURTON AND SPEKE
Richard Burton John Henning Speke were two Englishmen who left Zanzibar in 1856 on a journey to the interior of East Africa. Their objective was to find out the source of the River Nile.
In august 1858, Speke reached Lake Victoria and guessed that it was the source of the River Nile.
HM STANLEY
Henry Morton Stanley, a journalist was sent by an American newspaper to prove if indeed Lake Victoria was the source of the River Nile as Speke had guessed. In two subsequent journeys, Stanley explored the country between Lake Edward and Lake Victoria.
The work by HM Stanley
VASCO DA GAMA
Vasco da Gama was born to a noble family in Jines, Portugal in 1460. Vasco da Gama was a Portuguese explorer who discovered the ocean route from Portugal to the east.
He sailed from Lisbon, Portugal on July 8, July 1497 heading eastwards. He was sent by King Manuel the first of Portugal.
Vasco da Gama reached the Cape of Good Hope in South Africa on November 22, 1497 and he continued on to India. After many stops in Africa and problems with Muslim traders who did not want interference in their profitable trade routes, Vasco da Gama reached Calcutta in India on May 20, 1498.
He returned to Lisbon, Portugal in September 1499. Along the way, many crew members died from scurvy caused by lack of vitamin C.
Upon his return, Vasco da Gama was treated as a hero and was rewarded by the king.
King Manuel 1 of Portugal then sent Vasco da Gama on another expedition to India (1502-1503). On this second trip, Vasco da Gama took 20 armed ships because he anticipated problems from Muslim traders.
On this voyage, Vasco da Gama killed hundreds of Muslims in order to demonstrate his power. After King Manuel’s death, King John the third sent Vasco da Gama to India again.
Vasco da Gama died of an illness in India on December 24, 1524 and his remains were returned to Portugal for burial.

TRANSPORT SYSTEMS OF AFRICA
Transport is a means of moving people from one place another.
Transport is also a means of carrying raw materials and manufactured goods to places where they are needed.
TYPES OF TRANSPORT SYSTEMS IN AFRICA
There are a number of roads in Africa which connect major cities with each country and also to different countries.
Some of the major roads are:
There are some areas in Africa which have few or no roads because of mountains, lakes, seas and deserts. For example, there is no major road between North Africa and West Africa because of Sahara Desert.
The Congo Basin has almost no roads because of the rainforest and many rivers.
The types of vehicles that use the roads include small cars, lorries, buses, trucks, oil tankers, bicycles and ox-carts.
In general, Eastern and Southern Africa have more railway lines as compared to West Africa and North Africa.
The Sahara Desert and Congo Basin are a hindrance to rail construction.
Africa is surrounded by three water bodies:
A seaport is a place where ships stop to load and offload goods and passengers.
The major sea routes:
The Suez Canal is a passage which was dug through a piece of land to connect the Mediterranean Sea with the Red Sea. This enables big ships to pass through the canal shortening the distance between Europe and Asia.
Air transport is the fastest means of travelling. However, it is very expensive.
There are two types of air transport services provided in Africa. These are:
Domestic air services
Domestic air services refers to air transport provided within each country. For example, from Lilongwe to Blantyre and Mzuzu within Malawi.
International air services
International air services refers to air transport provided to enable people to travel to other countries within Africa and also outside Africa to Europe, America, Asia and Australia.
Air transport also carries goods like mail clothes and medicines. Such goods carried by a plane are called cargo.

THE DUTIES OF TRAFFIC POLICE AND WARDENS
Traffic wardens are people assigned the duties of traffic control. Examples of traffic wardens are scholar patrols.
These scholar patrols are school children that stop cars for fellow school children to cross the road near schools that are located along busy roads.
Other examples of traffic wardens are city assembly workers working in towns, airports, hotels and private companies. All these help to regulate traffic in these places.

Air is a substance which embraces the whole atmosphere. Air is used by both plants and animals.
IMPORTANCE OF AIR
HOW AIR IS POLLUTED
Air pollution occurs when air contains gases, fumes or odour in harmful amounts. These amounts of fumes or odours can be harmful to the health and comfort of people.
These can also cause damage to plants and animals.
The substances that cause air pollution are called the pollutants.
Air pollution mainly occurs as a result of gaseous discharges from industries and motor vehicles. There are also natural sources such as wind-blown dust and smoke from fires.

Natural resources are things that are provided by nature.
THE NATURAL RESOURCES OF SOUTHERN AFRICA
Mountains
Examples of mountains are Mulanje in Malawi; Kilimanjaro in Tanzania; Drakensberg in South Africa.
Minerals
Examples of minerals are gold in South Africa; uranium and bauxite in Malawi; copper in Zambia; diamond in Botswana and South Africa; coal in Malawi, Zimbabwe and South Africa
Water
Water is mostly found in lakes and rivers such as Lake Malawi, Lake Tanganyika, Shire River and Zambezi River, Limpopo River, Orange River, Rufiri River, Luangwa River as well as Caborabasa Dam and Kariba Dam
Soils
Examples of soil are clay, sand, roam and alluvial soil.
Air
This is manly composed of oxygen, carbon dioxide and nitrogen.
Wild animals
These are animals that live naturally in the bush. They are not kept by people. Most of these animals are kept in protected areas that are called national parks or game reserves.
Such protected areas include Serengeti in Tanzania, Liwonde in Malawi and Luangwa in Zambia.
Forests and other vegetation
There so many forests in Southern Africa and the general vegetation is quite varied
Fish
Some examples of fish are chambo, usipa, mlamba, kapenta and bakayawo. These are found in Lake Malawi and Lake Tanganyika, Indian Ocean and Atlantic Ocean.

UNIT 1 SCIENTIFIC INVESTIGATIONS
STAGES OF A SCIENTIFIC INVESTIGATION
There are six stages of scientific investigation. These are:
These six stages can be summarized into three main stages which are:
PLANNING STAGE
This stage involves a number of steps.
The first step is to identify the problem to be investigated.
The second step is to write the statement of the problem in the form of a question The third step is to predict or guess the answer to the question or problem.
The predicted answer is called a hypothesis.
The next step is to identify what is going to be observed and measured.
These are the factors that would affect the results of the investigation which are called variables. A variable is anything that can change.
The next step is to identify the materials that will be required to carry out the investigation.
The last step of the planning stage is to come up with steps to be followed in the process of collecting data.
The above steps of the planning stage of an investigation are summarised as follows:
Step 1 identifying the problems to be investigated
Step 2 writing a statement of the problem to be investigated in the form of a question
Step 3 predicting or guessing the answer to the question, that is, coming up with a hypothesis
Step 4 identifying the variables
Step 5 identifying the materials required for carrying out the investigation
Step 6 coming up with the procedures for carrying out the investigation
IMPLEMENTATION STAGE
The second stage of a scientific investigation involves implementing the plans that were developed during the planning stage.
This is the stage which the hypothesis are tested by carrying out the investigation.
During this stage, the variables to be investigated are deliberately changed while keeping the other variables constant.
The variables that are changed are observed and recorded as the investigation is being conducted. The purpose of carrying out an investigation is to collect data through observation.
If one is not satisfied with the data that has been collected, it is necessary to repeat the procedures. The data that is collected should be organised and presented in a meaningful way.
There are several ways of presenting data. These include tables and graphs.
When presenting data in the form of a graph, it is important to remember that:
When data has been collected, it should be organised in such a way that it is meaningful. The procedures of organizing data are referred to as data analysis.
One way of analysing data is the use of graphs.
Once the data has been analysed, there is need to interpret it.
The interpretation of data involves determining the relationship between variables using the analysed data.
The methods of determining the relationships between variables include:
In summary, the implementation stage of scientific investigation involves the following:
Step 1 carrying out the investigation according to the plans. Step 2 collecting data and presenting it in a meaningful way. Step 3 analyzing the collected data.
Step 4 interpreting the analyzed data.
CONCLUDING STAGE
The last stage of a scientific investigation is the concluding stage.
During this stage, the hypothesis is evaluated against the interpretation of the data.
That is, the relationship between variables that has been determined from the data is compared with the hypothesis of the investigation.
If the determined relationship from the analysed data agrees with the hypothesis then the hypothesis becomes the conclusion of the investigation.
If the hypothesis is different from the relationship determined from the results of the investigation then the hypothesis is not true.
What is important is that the conclusion must be based on the results of the investigation and not on the investigator’s wishes.
REPRODUCTIVE PARTS OF HUMAN BEINGS
The male reproductive parts or organs are:
The testes produce and store the sperm.
The penis is for reproduction and for passing out urine.
The female reproductive parts are:
Egg cells are produced in the ovaries.
The egg travels through the oviducts or fallopian tubes.
The vagina is the passage for sperm during sexual intercourse and is also the birth canal.
FERTILIZATION IN HUMAN BEINGS
Reproduction in human beings involves special sex cells. These sex cells are the egg and sperm.
The sperm is the male sex cell while the egg is the female sex cell.
During mating, the penis is inserted into the vagina. The seminal fluid which contains millions of sperm is then released into the vagina.
Sperm and egg cell unite Fertilization is the union of the sperm and egg (ovum).
After fertilization has happened, the fertilized egg moves down the fallopian tube to the uterus as it develops into an embryo.
In the uterus, the embryo attaches itself to the wall. The umbilical cord joins the embryo to the mother.
An embryo attached to uterus wall
The developed embryo usually takes about nine months before it is ready to be born.
When a baby is born it grows into a child, an adolescent and finally becomes an adult.
MISCONCEPTIONS ABOUT PREGNANCY
Some teenagers have misconceptions about pregnancy.
They think that a girl cannot have pregnancy if she does the following:
THE HUMAN BRAIN
The human brain is located in the skull.
It consists of three main parts:
CEREBRUM
Cerebrum is the front and largest part of the brain.
It is responsible for:
CEREBELLUM
Cerebellum is the middle part of the brain.
It is responsible for:
MEDULLA OBLONGATA
Medulla oblongata is the part below the cerebellum
It is responsible for:
THE RELATIONSHIP BETWEEN THE BRAIN AND SENSE ORGANS
The brain is connected to different sense organs through nerves, via the spinal cord. The sense organs are eyes, ears, skin, nose and tongue.

CLASSIFICATION OF PLANTS
There are two major groups of plants:
FLOWERING PLANTS
Flowering plants produce flowers.
Examples of flowering plants are maize, rice, mangoes and beans
NON-FLOWERING PLANTS
Non-flowering plants do not produce flowers.
Examples are algae (ndele), mosses, liverworts, ferns, mushrooms, lichens, pine and cedar.
USES OF FLOWERING AND NON-FLOWERING PLANTS
PARTS OF A FLOWER
A flower has internal and external parts.
The stamen is the male part of a flower consisting of the anther and the filament. The pistil is the female part of the flower. It consists of the stigma, style and ovary. The ovary keeps ovules which develop into seeds.
The ovary becomes a fruit.
The stamen, petals and sepals wither and fall off when the fruit has been formed.
FUNCTIONS OF THE PARTS OF A FLOWER
Part of a flower |
Function |
Flower stalk |

Anthers |
Produce pollen grains |
Filaments |
Holds anthers |
Stigma |
Receives pollen from anthers |
Style |

POLLINATION AND FERTILIZATION
Flowers are important parts of plants. They are reproductive parts.
Reproduction takes place through the processes of pollination and fertilization.
POLLINATION
Pollination is the transfer of pollen grains from anthers to the stigma.
There are different types of pollination. These are:
Self pollination is the transfer of pollen grains from anther of a flower to the stigma of the same flower or another flower on the same plant.
Cross pollination is the transfer of pollen grains from the anther of a flower to the stigma of another flower on another plant of the same kind.
Things that help the transfer of pollen from anthers to the stigma are called agents of pollination. These include bees, butterflies, birds, wind and water.
INSECT AND WIND POLLINATED FLOWERS
Insect pollinated flowers are different from wind pollinated flowers.. The following table shows some of the differences.
INSECT POLLINATED FLOWERS |
WIND POLLINATED FLOWERS |
Flowers are large to be easily seen |
Flowers are usually small |
Petals are usually brightly coloured |
Petals are dull coloured |
They produce scent to attract insects |
They have no scent |
They produce nectar |
They have no nectar |
Small quantities of sticky pollen are produced |
Large quantities of light pollen grains are produced |
Anthers hold firmly |
Anthers hang loosely so that pollen can be blown |
FERTILISATION
Fertilization is the union of male gamete and female gamete.
When a pollen grain lands on stigma, it grows to form a tube called a pollen tube which grows towards the ovule.
The pollen tube continues to grow down the style until it reaches one of the ovules in ovary.
When this happens the male part (male gamete) contained in the pollen tube unites with the female part (female gamete) inside the ovule to form a zygote.
The zygote develops into a seed.
The following instruction shows pollen tubes growing towards ovules.
After fertilization has taken place, the petals, stamen and style wither. The ovary then develops into a fruit.
HOW FRUITS AND SEEDS ARE DISPERSED
Fruits and seeds can be scattered from the parent plant.
Dispersal is the scattering of fruits and seeds from the parent plant.
There are different ways and agents by which fruits and seeds can be dispersed. These include wind, animals, explosive mechanism and water.
Fruits and seeds which are dispersed by wind are light and have wing-like structures or hairs. These features help the fruits and seeds to be carried away from the parent plant by wind.
Examples of fruits and seeds which can be dispersed by wind are those from cotton, Tridax and m’bawa.
The following illustration shows some of the examples of wind dispersed fruits and seeds.
Fruits and seeds that are dispersed by animals are either succulent or have hook-like features or sticky fluid which make them to stick to the body of animals or clothes.
Large, brightly coloured or scented fruits also attract animals and in the process dispersion can take place.
Examples of fruits and seeds that are dispersed by animals include oranges, tomatoes, black jack, guavas, mangoes, hedgehog grass and peaches.
The following illustration shows some examples of fruits and seeds that can be dispersed by animals.
Fruits and seeds that can be dispersed by water are less dense than water. An example of fruits that can be dispersed by water is a coconut fruit.
The following illustration shows a coconut fruit.
Some fruits and seeds are dispersed by explosive mechanism (bursting). These fruits and seeds have pods.
When the pods have dry, they suddenly open and scatter the seeds away from parent plant due to the expansion and contraction of the pods.
Examples of seeds that can be dispersed in this way are castor oil, peas, beans and chitedze. The following illustration shows some seeds that can be dispersed by explosive mechanism.
Fruit dispersal and seed dispersal are important because they help to scatter fruits and seeds thereby reducing the competition for space, air, moisture and mineral salts.
Plants grow well when they are well spaced.
CONDITIONS FOR SEED GERMINATION
For a seed to germinate, it requires moisture, warmth and air.
It is possible to show through experiments that these conditions are necessary for seeds to germinate.
The illustrations below show the external and internal parts of a bean seed.
During germination, a bean seed undergoes five stages. The illustrations below show the stages.

MEANING OF DIGESTION
Digestion is the process by which insoluble food, consisting of large molecules, is broken down into small soluble molecules.
The small molecules, in solution form, pass through the walls of the intestine and enter the blood stream.
Digestion and absorption of food take place in the alimentary canal.
PARTS OF THE DIGESTIVE SYSTEM
The digestive system consists of the alimentary canal and related organs.

MOVEMENT OF FISH
Fish move in water by swimming.
They have fins and a streamlined body which make them possible to move rapidly in water. The following illustration shows the external parts of a fish.
TYPES AND FUNCTIONS OF FINS
The key function of fins is to help the fish balance and turn as it swims.
Dorsal fin protects the fish against rolling, and assists in sudden turns and stops.
Ventral fin assists with moving up and down through the water, turning sharply and stopping quickly
Caudal fin is the main propelling fin in most fish
Anal fin helps to maintain stable equilibrium
A pair of fins used for balancing and braking
Adipose fin’s function not yet proven by scientists. Some said it serves as a pre-caudal flow
PROTECTION MECHANISMS USED BY SOME VERTEBRATES
Vertebrates have different mechanisms for protecting themselves.
These include biting, changing colour (camouflage), producing a hissing sound, running away, good eye sight and hiding.
INVERTEBRATES
Invertebrates can be classified into four groups, namely, protozoa, worms, molluscs and arthropods.
These are also called microscopic animals.
Some of them live in seawater or fresh water while others live in bodies of other animals. Examples of protozoa include amoebas, plasmodia and trypanosome.
Amoebas are found in the mud in ponds.
They reproduce by dividing into two in a process called binary fission.
Binary fission is an example of asexual reproduction which does not involve the fusion of male and female gametes.
Worms can further be classified into the following groups:
Flatworms can be divided into two groups. These are free-living and parasites.
Planaria are examples of free-living flatworms while flukes and tapeworms are parasites. Blood flukes cause bilharzia in human beings.
Roundworms are also known as nematodes.
Some of the roundworms are free-living while others are parasites.
Ascaris, hookworms, filarial worms, and pinworms are examples of roundworms.
They include earthworms and leeches.
The body of the worm is divided into several segments, hence the name segmented worms.
Molluscs are animals with shells.
Molluscs have soft and non-segmented bodies.
Examples of molluscs are snails, octopuses, slugs, oysters. Many of molluscs live in water.
These are animals with jointed legs.
Arthropods form the largest group of invertebrates which include insects, crabs, millipedes and spiders.
THREE MAIN COMMON CHARACTERISTICS OF ARTHROPODS
LIFE CYCLE OF A HOUSEFLY AND A GRASSHOPPER
Insects lay eggs which hatch into larvae.
In some insects larva changes to a pupa that develops into the adult form or imago.
The development in stages of an insect from the young to the adult is called metamorphosis.
There are two types of metamorphosis, namely, complete metamorphosis and incomplete metamorphosis.
In complete metamorphosis, an egg hatches into a larva, a larva develops into a pupa, which finally develops into imago or adult form.
Incomplete metamorphosis does not have pupa stage.
Insects such as houseflies and mosquitoes undergo complete metamorphosis.
Insects such as grasshoppers, bugs, termites and cockroaches undergo incomplete metamorphosis

DISADVANTAGES OF INVERTEBRATES
TYPES OF LEAVES AND ARRANGEMENT
There are different types of leaves.
The types can be explained in terms of their shape, arrangement and how they are attached to the stem.
There are various shapes of leaves.
The following illustration below shows some of the shapes of leaves
There are different leaf arrangements.
Some of these are shown in the following illustration below
There are two ways in which a leaf is attached to the stem.
One way is when a leaf is attached to a stem with a leaf stalk, for example: mango, tobacco, groundnuts and bluegum leaves.
Another way is when a leaf is attached to a stem without a leaf stalk, for example, maize, sisal, onion, and grass leaves.
Some leaves are simple while others are compound.
A simple leaf has one leaf blade attached to a leaf stalk.
A compound leaf has more than one leaf blade attached to a leaf stalk. The following instruction shows examples of simple and compound leaves.
a simple leaf a compound leaf
TYPES OF STEMS
There are different types of stems.
These include:
ERECT STEMS
Erect stems stand upright.
Examples of erect stems are those of maize, okra, bluegum, mango and pawpaw.
The illustration below shows examples of erect stems.
CREEPING STEMS
Creeping stems grow along the ground and produce roots as they grow on the ground, for example, kapinga grass, sweet potato and strawberry.
The following illustration below shows examples of creeping stem.
CLIMBING STEMS
Climbing stems have weak stems and they seek the support of standing objects to secure an upright position.
They do so by using tendrils and twisting around another plant.
Examples include pumpkins, Chitedze, kalongonda, granadilla and white haricot beans (kayera).
The following illustration shows examples of climbing stems
UNDERGROUND STEMS
Underground stems grow under the ground.
Some examples of underground stems are Irish potatoes, bananas, bamboos, and many grasses.
The following instruction show example underground stems.
An Irish potato has curved marks looking like eyebrows. These are buds. An Irish potato is a stem because it has buds.
Note that a sweet potato is a root while an irish potato is a stem.
This is because sweet potato tubers are not normally used when planting sweet potatoes. Stem cuttings are used when propagating sweet potatoes.
TYPES OF ROOTS
There are different types of roots.
These include:
A TAP ROOT
A tap root grows deeper and bigger as a plant grows. In woody stems, other roots branch from the tap root. Trees and shrubs have tap roots.
They keep the big trees fixed to the ground firmly to stop them from falling.
The following illustration below shows a tap root system
FIBROUS ROOTS
Fibrous roots grow spreading from the base of the stem. The roots are small, thin and normally similar in size.
Examples include maize plant and grass roots.
The following illustration shows fibrous roots
TUBEROUS ROOTS
Tuberous roots do not have buds.
Examples of tuberous roots are carrots, cassava, sweet potato and turnips.
The following illustration below shows tuberous roots
ADVENTITOUS ROOTS
Adventitious roots grow from the base of underground stem, for example onions.
The following illustration shows adventitious roots.
PROP ROOTS
Prop roots develop from the lower nodes of a plant and extend down into the soil.
Prop roots can be found growing on plants such as rice, wheat, oats, sorghum, maize, elephant grass and bamboo.
The following illustration below shows prop roots.
AERIAL ROOTS
Aerial roots grow on stems of plants such as kachere and mkundi. These roots grow outside the soil.
The following illustration below show aerial roots.
STEWING AS A METHOD OF COOKING
Stewing is a method of cooking food in a liquid for a long time to soften it. The food is cooked below the boiling point.
Stewing can be done on an open fire, on top of a stove or in an oven.
ADVANTAGES OF STEWING
DISADVANTAGES OF STEWING
GUIDELINES FOR STEWING
SUITABLE FOODS FOR STEWING
Suitable foods for stewing include tough pieces of meat, fish, beans, peas, fresh and dried fruits. The following is an example of a recipe using the stewing method
Ingredients
500g beef 2 onions
2 tomatoes
4 Irish potatoes
2 carrots
200g green peas Salt and pepper Oil for fry
Method
FRYING AS A METHOD OF COOKING
This is a method of cooking food in hot fat or oil. There are three methods of frying food.
Namely: dry frying, shallow fat frying and deep fat frying.
No fat or oil is used in this method. Food cooks in its own fat.
This method is suitable for very oily foods such as sausages, bwanoni, mafulufute, ngumbi and oily fish.
This method uses just enough fat or oil to cover the bottom of the frying pan to prevent the food from sticking to it.
Food is turned over to cook on both sides.
Suitable foods for shallow fat frying include chicken, eggs, pancakes and fish.
This method requires plenty of fat or oil, about half of the deep frying pan. The food is completely immersed or covered with fat or oil.
Suitable foods for deep fat frying include doughnuts, fritters, chicken, fish and chips.

SEDENTARY AND MANUAL WORKERS
People doing various types of work should have their nutritional needs met properly.
These people may be employed elsewhere or may be doing different types of work at home. Manual workers and sedentary workers are two basic categories of people doing work.
SEDENTARY WORKERS
These are people who are not involved in heavy work.
Their work is usually light and it is mostly done while sitting down in one place.
Sedentary workers are usually office workers such as secretaries, managers, television and radio presenters, reporters, lawyers, pilots, administrators, telephone operators and drivers.
Guidelines for planning meals for sedentary workers
Below are some sample menus for sedentary workers
Sample breakfast |
Sample lunch or supper |
Orange juice Rice porridge Coffee with milk |
Stewed fish Nsima |
Cooking and serving meals for sedentary workers
MANUAL WORKERS
Manual workers are people who do heavy work.
These people spend a lot of energy and lose a lot of water and salt through sweeting.
Examples of manual work include gardening, chopping wood, moulding bricks and carrying heavy things such as bags of maize or rice.
Guidelines for planning meals for manual workers
Below are sample menus for manual workers
Sample breakfast |
Sample lunch or supper |
Lemon juice Mgaiwa porridge Tea with milk |
Stewed dried fish Mgaiwa nsima |
Cooking and serving for manual workers
Cooking promotes palatability and digestibility of foods.
Food for manual workers should be cooked using suitable methods of cooking. Hence, meals for manual workers can be boiled, fried, stewed, roasted or baked.
Combining several foods in one pot helps to increase energy value of the foods especially if the foodstuffs used are of high energy value.
Such foods may include groundnut flour in vegetables or porridge, potatoes in meat, bean or chicken stew, fats such as margarine and butter in porridge or on bread and sugar in sweet dishes.
STAINS
Laundry involve a lot of processes.
One of such processes is removing stains from garments and articles.
A stain is a discoloured mark caused by spilling of foods and liquids on garments and articles. These stains cannot be removed by the normal way of washing.
There are many different types of stains which can discolour our garments and articles.
These stains are classified according to their origins:
How these stains are treated depends on the chemical nature of the stain, the age of the stain, texture and colour fastness of the fabric stained.
However it is important to remove the stains before the normal washing of clothes because the washing process tends to fix some stains.
For good results, it is advisable to identify the cause of the stains and remove them as soon as they occur.
STAIN REMOVAL
General principles of stain removal
WAYS OF REMOVING COMMON STAINS
They usually contain acid.
To remove them, pour boiling water through the stain at once. If it is not removed, use ammonia or borax and boiling water.
If it persists repeat the process
These are vegetable stains.
For fresh stains, cover with salt at once and pour boiling water. If unsuccessful, use lemon juice and salt.
If the stain persists use bleach.
These are animal stains.
They contain albumen and are set by hot water. Therefore, soak in cold water and wash with soap. If unsuccessful, steep in cold water and salt.
If the stain is fresh, rub it gently with a softened pad moistened with ammonia and paraffin. Remove all traces of grease and wash the article thoroughly with hot water and soap.
This is a vegetable stain.
Apply methylated sprits, rubbing the stain gently with a pad of soft cotton.
Sponge with methylated spirits. If the stain is stubborn, use ammonia.
Rub with ice-cube to set the chewing gum so it may be removed.

TECHNOLOGIES FOR DOMESTIC USE
The technologies for domestic use are those that are used in the home.
These technologies include the following:
MAKING TECHNOLOGIES FOR DOMESTIC USE
Learners can make different types of technologies that can be used for domestic use. Making such technologies involves a number of steps.
These are:
The first step is to identify the problem to be solved.
The second step is to find out as much information as possible about the problem. This may involve research, for example, by asking other people or reading about the problem.
The third step is to plan how you will solve the problem. This step involves brainstorming, considering different solutions and choosing an idea or solution that can be tried.
When a solution has been decided upon, you need to outline the process to be followed when designing the technology.
This would involve thinking about:
This step involve getting the necessary tools and other material to make the technological device
Once the technological device has been made, it should be tested to see if it works according to expectations. If not, the whole process should be reviewed to identify and rectify any problem.
Evaluation should take place at each step of the technological process in order to assess how the production is progressing.
UNIT 17 PROPERTY OF LIGHT, HEAT AND SOUND
PROPERTY OF LIGHT
Light has several properties.
The list below shows some of the properties of light:
LIGHT TRAVELS IN A STRAIGHT LINE
This property of light can be proved through experiments. The action of a pinhole camera and three identical rectangular cards with tiny holes at their centres arranged in a straight line proves that light travels in a straight line.
The following diagram shows what happens when light enters a pinhole camera and when light is shone on one rectangular card that is aligned with other two cards.
REFLECTION OF LIGHT
Light can travel through a vacuum and some media that are transparent. Light is reflected (bounced off) by certain media. Mirrors are good examples of objects that reflect light. Reflection of light from smooth surfaces is done in a special way. A ray that is incident on a mirror surface is reflected following the laws of reflection.
The diagram that follows shows reflection based on the law that states that the angle of incidence (angle between the incidence ray and normal) is equal to the angle of reflection (which is the angle between the normal and the reflected ray). The light that strikes the mirror surface at 900 is reflected along the same path.
REFRACTION OF LIGHT
Refraction is the sudden change of direction of light as it travels from one medium to another of different optical density. When an incident ray goes from a less dense medium like air to a denser medium like a glass block, the refracted ray is always refracted towards the normal. As the refracted ray travels from the glass to air, once again, it is refracted away from the normal.
The diagram that follows shows light travelling from a less dense medium to a more dense medium, and then to a less dense medium, once again.

PROPERTIES OF HEAT
Heat energy can be absorbed or lost by a substance. The heat energy lost by one substance is transferred to another substance even if there is no contact between them. Heat travels through various substances at different speeds.
The speed of heat in a substance may depend upon the nature of the substance and closeness of the particles in the substance.
As heat flows through substances it can:
TECHNOLOGIES BASED ON THE HEAT
Substances normally expand as heat passes through them. Thermometers are constructed based on the expansion and contraction of the liquid that is used. Some joints are made based on the principle of expansion and contraction.
There are technologies that have been made to cool a device so that it contracts for it to fit into the hole of another device. On expansion, the material firmly fits into the hole thereby making an extremely strong joint.
Such joints exist in bicycles, cars and other heavy machinery. Automatic switches (thermostats) in electric pressing irons and geysers work on the principle of expansion and contraction.
Vacuum flasks have been designed to employ some of the properties of heat. The vacuum flasks have a glass that has the inner part and its outer surface silvered.
The silvered surface radiates (emits) very little amount of heat and absorbs very little heat from its outer surface since polished (shiny) surfaces are bad radiators or emitters of heat.
The diagram below shows a vacuum flask.
A vacuum flask
Thermometers, cooling systems in cars and industries, electric pressing irons and geysers are some of the technologies that use properties of heat.
PROPERTIES OF SOUND
Sound is produced by anything that is vibrating. Just like heat, sound can be absorbed, transmitted through substances, reflected and refracted.
An echo is a good example of reflected sound. Sound travels at different speeds in different materials.
Sound requires a medium for its transfer. Sound spreads out in all directions from the source of production.
TECHNOLOGIES THAT USE THE PROPERTIES OF SOUND
There are a number of technologies that use properties of sound.
These include musical instruments such as a xylophone, mabatcha/badza, guitar, drum, flute, piano, trombone and trumpet.
TYPES OF FORCES
a pull
a push
A force can be a pull or a push that can change the state of rest of an object. The diagram that follows shows the illustrations of a pull and a push.
Different bodies can exert a pull or a push on objects. The earth exerts a force of attraction on objects. The force the earth exerts on objects is called the force of gravity or the gravitational force.
Gravity is defined as the pull of the earth. When one object moves or tries to slide over another object, a force to oppose the motion arises.
The force that is produced as a result of sliding or rubbing two bodies together is known as the frictional force or friction.
One can also produce an electrostatic force. This type of force can be produced by rubbing the plastic case of a ball point against the hair or fur. When the case is brought close to small pieces of paper it attracts them.
This happens because of the force of attraction that exists between the pen and the pieces of paper. This attractive force is called an electrostatic force.
The diagram that follows shows a ball point case picking small pieces of paper.
Magnets also exert forces on each other as well as on materials that are magnetic. The force which a magnet exerts is called magnetic force.
The magnets will attract each other if unlike poles of the magnets face each other. Otherwise, a force of repulsion will exist when like poles of magnets face each other.
The following diagrams show attractive and repulsive forces between unlike and like poles of magnets.
lines of force around a magnet
A stretched elastic band possesses strain energy. The band can exert a force on other objects. The force that the elastic band exerts is called an elastic force. The forces that have been discussed so far are just a few examples of the many different types of forces that exist.
USES OF FORCES
TECHNOLOGIES THAT USE THE PRINCIPLES OF FORCE
Nutritional deficiency diseases are due to lack or shortage of a particular nutrient in the diet.
When the body cannot cope with the little amounts supplied, specific signs and symptoms appear. Various nutritional deficiency diseases show different signs and symptoms.
Some of the deficiency diseases which affect people especially children are night blindness, scurvy, rickets, anaemia and goiter. These deficiency diseases can be prevented and treated.
NIGHT BLINDNESS
Night blindness is caused by lack of vitamin A in the diet. This deficiency disease is characterized by inability to see in dim light, dry and rough skin, and skin infections.
SCURVY
Scurvy is caused by lack of vitamin C in the diet and it is characterized by bleeding of gums, slow healing wounds, slow growth in children and loose teeth.
The illustration below shows a person with scurvy
ANAEMIA
Anaemia is caused by lack of iron in the diet and it is characterized by tiredness, pale hands, pale mouth, pale skin, pale mucus membranes and pale eyes and heart palpitations
GOITRE
Goitre is caused by lack of iodine in the diet. It is characterized by slow growth in children and an enlarged gland at the front of the neck.
The illustration below shows a person with goitre
RICKETS
Rickets are caused by lack of vitamin D in the diet and are characterized by soft bones. The teeth are also affected.
Due to the weight of the body, the soft bones of the legs bend outwards. Rickets mostly occur in children.
The illustration below shows a child with rickets
PREVENTIVE MEASURES AND TREATMENT OF DEFICIENCY
Nutritional deficiency diseases can be prevented by ensuring that the nutritional needs of various members of the family, especially children, are met through a proper diet. As such, families are to eat a variety of foods in the right amounts. Once affected by this nutritional deficiency diseases they can be treated the first step in treating deficiency diseases is diagnosis. There after the treated can be corrected supplying the missing nutrients in the diet. Nutrients supplements are used where the condition is severe.

DYEING FABRICS AND OTHER MATERIALS
The process of dyeing fabrics and other materials can be done in different ways depending on the type of dye to be used.
Dyes come in different names such as dylon, dryad and reeves. These are suitable for dyeing natural fibres and good for commercial purposes.
These can be bought from shops. Dyes can also be made locally. These include boiled concentrated solution of tea leaves, inks, maroon coloured leaves of maize, onion skins, red cabbage, mushrooms, carrot tops, spinach and roots of some trees, for example n`joka in Yao.
It is essential to know the reaction of different types of dyes to fabrics and other materials. Different fabrics and other materials absorb dyes differently.
Fabrics made from natural fibres, for example, cotton, linen, and woollen materials dye more readily than fabrics made from artificial fibres, for example, nylon and terelyne.
Materials made from natural fibres give best results for dyeing because they readily absorb dyes.
Cotton fabrics and garments are the best for dyeing purposes. Cotton fabrics can easily be identified by burning a piece of fabric. Cotton fabrics will burn like wood, producing ash.
If the fabric shrinks, it is not cotton.
Other ways of identifying fabrics and other materials that are good for dyeing include:

Note
USING NATURE DYES
Note
The water should be just enough to cover the fabric to the dyed. Sometimes chemicals are added to the natural dyes to facilitate the absorption of the dyes.

THE MENSTRUAL CYCLE
At puberty, girls will start producing egg cells. An egg is produced every month by one or both ovaries. This is called ovulation. Ovulation has a reproductive function. When the egg cell is fertilized, the results is pregnancy.
When ovulation is happening, the wall of the uterus becomes thick as it prepares to receive an embryo after fertilization. When the egg is not fertilized, it dies. The wall of the uterus then breaks down leading to a discharge of bloody material. This discharge of bloody material is called menstruation. Menstruation happens every month, hence it is called menstrual cycle.
Menstruation lasts about 7 days. Menstruation is a normal thing for girls. It may start at the age of 11 in some girls is as late as the age of 18 in others. A women menstruates up to the age of 45 to 50.
During menstruation, girls need to take extra care of themselves. They can do this by:

IMPORTANCE OF HOME BASED CARE AND SUPPORT
As people live together in a school, community or family they are bound to be involved in conflicts or disagreements because they have different interests, opinions, beliefs and views.
For them to live together peacefully, they need to learn to resolve these conflicts peacefully.
WAYS OF RESOLVING CONFLICTS PEACEFULLY
Negotiation is a process where people who are involved in conflicts come together and talk to each other about the conflict.
Mediation is a process where two persons who are in conflict involve a third person to help them come up with the solution to the problem. This person is called a mediator.
Arbitration a process similar to mediation, however, the third person that is involved is called an arbitrator. The arbitrator acts like a judge as he or she gives the final judgement as to who is right and who is wrong.

MISCONCEPTIONS ASSOCIATED WITH THE USE AND ABUSE OF DRUGS AND SUBSTANCES
SITUATIONS WHICH PROMOTE ABUSE OF DRUGS AND SUBSTANCES
Some cultures tolerate the use of substances such as alcohol and chamba during ceremonies such as weddings and funerals.
These make boys and girls start taking drugs and substances in order to forget their problems. As a result, they may engage in unprotected sex thereby contracting STIs including HIV and AIDS.
Sometimes loneliness can influence some people to start taking drugs and substances.
Some youths may abuse drugs and substances because they see others doing the same.
HOW ABUSE OF DRUGS AND SUBSTANCES CAN EXPOSE THE YOUTH TO HIV AND AIDS
Peer guidance and counselling is where members of the same age group come together to help one another solve their problems.
The youth who are empowered have high self esteem and are able to stand for their rights.
While they may empowered by their parents and teachers, it is necessary that youths of the same age, class, group or school listen to and help each other on how to address the everyday challenges.
Youths must assist one another by finding solutions to their own problems by sharing experiences on how some of them addressed similar challenges.
This can be done through narrating the stories, sharing health talks, one-to-one talks, debates, songs, poems and drama
CHALLENGES THAT THE YOUTH ENCOUNTER
Sexual abuse
It is very common these days to hear that young people are sexually abused by adults. These adults may take advantage of the youth by offering them rewards such as money and gifts.
In schools, some teachers who are not responsible enough may promise girls and boys high grades in exchange for sexual favours.
This puts the youth at risk of contracting STIs including HIV and AIDS. It is therefore important that the youth resist and report such incidences.
Drug and substance abuse
Due to negative peer pressure, some learners indulge in drug and substance abuse. Alcohol and chamba make it difficult for one to say “no” to premarital sex which contributes to teenage pregnancies, STIs including HIV and AIDS, school drop outs and finally death.
Orphanhood
Orphans usually suffer grief and confusion. This is worsened by prejudice and social exclusion which may lead to dropping out of school and lack of health care. The resulting poverty and lack of support can expose them to risks such as contracting HIV and AIDS.
WAYS OF ADDRESSING CHALLENGES THAT THE YOUTH ENCOUNTER
SITUATIONS THAT MAY REQUIRE DECISION MAKING AND PROBLEM SOLVING SKILLS
Adolescence
This is the time when youths undergo physical, emotional and psychological changes. They begin to search for their identity.
Sexual relationships
Due to physical and psychological changes, youths become curious to know the physical changes of the opposite sex. In addition to this, they become sexually attracted to members of the opposite sex.
Peer pressure
This is the influence by members of the same age group to behave in a particular way. Peer pressure may have both positive and negative effects.
Culture practices
Some cultural practices can lead to the spread of STIs including HIV and AIDS because they encourage young people to indulge themselves in risky behaviours such as early sex and drug and substance abuse. Such cultural practices are initiation ceremonies, chokolo, fisi, kusasa fumbi and mbirigha.

The physical changes in boys and girls during adolescence tend to influence their psychological changes.
This is because at this stage the sex hormones called testosterone in boys and oestrogen in girls are being produced. These hormones influence their emotional behaviour.
Sex refers to one’s reproductive system which differentiates males from females. Sexuality is the total expression of who one is as a human being whether male or female.
SOURCES OF INFORMATION ON SEX AND SEXUALITY
Parents are an important source of information from which children learn about sex and sexuality. As parents teach children about accepted codes of conduct and behaviour, they learn about sex and sexuality
Mass media such as television, radios, newspapers and magazines contribute a lot to information on sex and sexuality.
Peers is another important source of information from which children learn about sex and sexuality. They acquire knowledge about males and females. In addition, they learn about their roles as they play and work together at school and home.
Children learn a lot about sex and sexuality by observing what goes on in their community. They also learn through interaction with the members of the community during initiation ceremonies.
Religion is another source of information to children on sex and sexuality. It teaches different principles of moral behaviour. As children learn about these moral principles they also acquire information about sex and sexuality.

STAGES IN THE PLANNING PROCESS
Planning involves many stages. Some of the steps are:
Outlining activities one wants to do
After the goals have been identified, you think of the resources that you need to achieve your goals. These may include human, material, time, monetary resources. This needs skills such as decision making, creative thinking and critical thinking.
Selecting alternative ways of achieving your goals by choosing what activity to do.
Translating the plan into action or doing the activity using the resources available.
This is making a follow up to see the progress of the activity to do
Assessing what has been done. You actually judge whether the activity is being done according to your plan.
