Topic: Environmental Quality
Learning objectives: by the end of the lesson, pupils should be able to;
i. Tell what environmental quality is;
ii. Appraise healthy environment;
iii. Differentiate between a healthy and a degraded environment
iv. State the disadvantages of degraded environment
v. Describe the factors which degrade the environment
RESOURCES & MATERIALS: videos, posters, pictures, waste bins, charts, etc.
PREVIOUS KNOWLEDGE
A good or bad environment is characteristics by a certain future. The pupils can identify the good
features of environmental quality.

CONTENT
People live in rural areas (cities) and in urban areas (villages). However, the quality of the
environment of either area is determined by these factors:
• Clean/ fresh air.
• Clean stream water.
• Less noise.
• Fewer refuse heaps.
• Less smoke from factories.
• Smaller amounts of waste fumes from vehicles, among many others.
The environment is not the same everywhere, even in the same city. The quality of the
environment differs from one place to the other. If an environment is only slightly polluted
and not over populated, we say the environment quality is good. If the environment is
highly polluted and maybe over populated, we say the environment quality is poor.
What is a Healthy environment?
A healthy environment is a clean and attractive area and hosts no harm to the people living there.
How to maintain a healthy environment:
• Keep environment clean at all times.
• Ensure that refuse do not lie about.

• Maintain less smoke in an area. Industries should not be built in residential areas and
vehicles should be on an average speed to avoid heavy exhaust.
• Tarred roads can prevent dust.
• Do not keep garbage/ refuse around residential areas to avoid bad smell.
• Human or solid waste should not be kept in compounds.
• Ensure the lawn is cut low.
• Beautify compounds with flowers.
• Apply insecticides and pesticides to avoid cockroach, mosquitoes, houseflies, etc.
• The environment should be kept less noisy. Do not use loud speakers that may affect
others in the neighborhood.
• Regularly sweep compounds.
PRESENTATION

including soil.
CONTENT
Erosion is one of the changes around us. It is a common occurrence in our localities. In Nigeria,
many lives and properties have been lost due to erosion problems in many communities.
Common causes of erosion are rainfall, flood events, wind. Also, certain human activities like
construction works and bush burning can expose the soil to erosion.
MEANING OF SOIL EROSION
Soil erosion is the washing away of top soil by water, wind and other agent of erosion such as
human activities.
The more soil that is washed or blown away from the surface, the deeper the erosion that is
caused.
TYPES OF EROSION
1. Water erosion
2. Wind erosion

MEANING OF WATER EROSION
Water erosion is the removal top soil by water such as running water, rainwater, river and sea.
MEANING OF WIND EROSION
Wind erosion is the removal top soil by wind.
LESSON 2 – CAUSES OF SOIL EROSION
1. Rainfall and flood
2. Soil texture
3. Overgrazing
4. Deforestation
5. Bush burning
6. Overused of soil resources

CONTENTS:
What is Waste?
Waste is anything which is no longer require by its owner and therefore, should be thrown away.
They are known as unwanted substances used for domestic purposes. Waste is produced in the
homes, markets, offices and workplaces, playgrounds, factories, and in short, wherever people
work, play or rest.
Waste can be categorized into two forms: Solid waste and Liquid waste
What is Solid waste?
Refuse, or solid waste, consists of solid materials with two major components: garbage, or food
wastes, and trash e.g. plastic bottles, paper, empty cans, etc.
What is Liquid waste?
Sewage or Liquid waste can be defined as such liquids as wastewater, fats, oils or grease, used
oil, liquids, sewages, gases, or harmful household liquids.
If waste materials are left to lie about anyhow, there will be harmful results which may include
bad smell in the neighborhood, untidy environment, breeding of mosquitoes, possibility f injury
to children, etc.
Disposal of solid waste:
Refuse or solid waste can be collected in the following manners:
Refuse collection:

Refuse should be disposed in refuse cans. In every home, there should be two or more refuse
cans: one for bio-degradable materials (that is things that can decay), the other for things that do
not decay but can be burnt and the last one for things that can’t be burnt and do not decay e.g.
glass and metal.
Sorting refuse:
Grouping of refuse means separating refuse into those that can be biodegradable, those that can
burn and those that cannot burn.
Final disposal:
Substances that can decay are thrown away into farmlands where they decay and make the soil
more fertile. Substances that can be burnt are burnt in incinerators and the ones that cannot be
burnt are buried or used n landfills.
Disposal of liquid waste (Sewage):
Soakaway pits are provided in homes to dispose liquid wastes.
Factories should treat wastewater in order to filter harmful chemicals before allowing the waste
water to flow into water bodies.
PRESENTATION

4. mention three dangers of improper disposal of waste.
RESOURCES & MATERIALS: The teacher will teach the lesson with the aid of recycling
materials.
PREVIOUS KNOWLEDGE: The pupils can identify recycling products and what they are
made of.
CONTENT
ADVANTAGES OF PROPER WASTE DISPOSAL
1. Control spread of sickness and diseases
2. Protect our environment from pollution
3. Improve quality of life
4. Save money and resources
5. Enable waste reuse

EFFECT OF IMPROPER WASTE DISPOSAL
1. Pollution – land, water and air are contaminated.
2. Increase in flies e.g. breed mosquitoes, sun flies
3. Easy spread of sickness and disease by flies or rodents
4. Poor health
5. Endangered our lives
6. Death
Most people know the system of returning empty bottles of drinks or other liquid to the
distributors and the distributors taking them back to the manufacturing factory where they are
washed and re-used.
Imagine what would have happened to the environment if there was no system of returning the
empty bottles, there would possibly be bottles all over.
The system and idea of using the same thing again is what is referred to as recycling.
Not only bottles are being recycled, other materials like paper and metals can also be recycled.
How is paper recycled?
Paper is made from wood pulp which is gotten from wood logs.
Paper is used all over the world in printing newspaper, books, magazine, etc. Newspaper which
has been read are collected and taken back to paper factories, the factories then turn the old papers
back to pulp and uses them to make fresh newspapers. By this recycling, we make the environment
clean and save the trees that might have been cut down to make fresh pulp.
In essence, recycling is the act of reusing things that have been used before over and over again.
PRESENTATION
LEARNING ATIVITIES:
STEP 1: To introduce the lesson, the teacher revises the previous knowledge. Based on this, the
teacher asks the pupils some questions;
STEP 2: Teacher leads discussion on proper disposal of wastes

RESOURCES & MATERIALS: chart showing polluted water and air.
PREVIOUS KNOWLEDGE: pupils have learnt about their environment and what it consists
of.
CONTENT
POLLUTION
Our environment is made up of living and non-living components. The living components are
called biotic factors, while the nonliving components are called abiotic components. Pollution is
the introduction of harmful substances into the natural environment which causes an unfavorable
change in the environment. The harmful substances are called contaminants. These contaminants
make the environment unsafe for plants and animals, thereby becoming a threat to health and
constituting hazards to the living things.
Pollutants are substances that can contaminate the environment. They can be in liquid, solid or
gaseous forms.
WATER POLLUTION: Water pollution occur when water pollutants are released or
introduced into water bodies making it unfit for consumption.
Causes/sources of Water Pollution
• Untreated sewage released into water bodies.
• Human faeces, waste, or dead plant and animals dumped into water bodies
• Oil leakages (oil spillage) from tanks and pipes into rivers and other water bodies.
• Liquid wastes from industries released into water bodies.
Effects of Water Pollution.
• Water pollution causes the spread of water borne diseases
• Harmful contaminants introduced into water bodies kills water organisms. Like
fish, crabs,
• The harmful chemicals released into water bodies renders it unfit for drinking,
cooking or even washing.
• When water is polluted, it produces bad odour
• Water pollution reduces the amount of oxygen made available to water organisms
Control of water pollution

• Oil spillage should be avoided
• Dumping of refuse into water bodies should be avoided
• The use of chemicals to catch fish should be discouraged
• Industrial waste should not be dumped into water bodies,
• Water treatment and water waste recycling should be encouraged
• People should be educated on the dangers of polluting water bodies.
PERIOD 2
AIR POLLUTION.
Air is polluted when harmful substances are released into the atmosphere.
Causes/sources of Atmospheric Pollution.
• Release of smoke from burning bush or burning waste into the atmosphere.
• When gas is flared i.e. fumes of gases from factories released into the atmosphere.
• Fumes from exhaust pipes of vehicles
• Bad odour from waste, sewage, decaying plants and animals
Effects of Air Pollution.
• Air pollution causes lung cancer
• It is the cause of some plant diseases
• It causes irritation of the respiratory tract
• It causes skin irritation which can lead to some skin diseases.
• It causes other clinical illnesses like headache, runny nose, puffy eyes etc.
• It can lead to suffocation.
Prevention/Control of Air Pollution
• Government should make laws against activities that pollute the air like gas
flaring
• The general public should be properly enlightened about the dangers of polluting
the atmosphere.
• Industries and factories should be sited far away from where people live.
• The people should be educated on the health benefits of having and living in a
pollution free environment.
• The use of explosives around residential area should be abolished.

1. identify parts of a flower.
2. draw and label parts of a flower.
3. identify parts of flower that produce fruit.
4. explain the meaning of pollination.
5. state types of pollination.
RESOURCES & MATERIALS: 1. Life flowers e.g. hibiscus, cowpea flower
2. Chart or diagram of a flower, agents of pollination, development from flower to fruits.

PREVIOUS KNOWLEDGE: The pupils can identify different parts of flowers.
CONTENT
Flowers are part of the plants that are very attractive and beautiful.
For examples,
1. Aloe Vera
2. Hibiscus
3. Orchids
4. Calla Lilly
5. Cacati
6. Climbing ivy
7. Cordyline
8. Dumb cane
9. Red acalypha

10. Yellow bush, etc.
Some flowers produce the seeds that can become new plants while some flowers don’t.
PARTS OF FLOWERS
1. Pistil
▪ Stigma
▪ Style
▪ Ovary
2. Stamen
▪ Anther
▪ Filament
3. Calyx
4. Stem
2. Find out the different between anther to the stigma.

PARTS OF THE FLOWER THAT PRODUCE FRUIT
The part of flower that produce fruit is called ovary.
Ovary is where seeds are produced which later grow into young plants.
The ovary and the surrounding parts later become the fruit.
Ovary is also called as the seed box.
MEANING OF POLLINATION
Pollination is the process of moving pollen grains from the anther to the stigma.
Once the bee carried the pollen grains from anther to the stigma, fertilization begins.
Apart from insects, pollination also take place when the winds blow.
TYPES OF POLLINATION
There are two types of pollination –
1. Self-pollination
2. Cross pollination
SELF POLLINATION
Self-pollination is the movement of pollen grains from the anther to the stigma with the same
flower.
CROSS POLLINATION
Cross pollination is the movement of pollen grains from the anther of one flower to the stigma of
different flower.
Male and female of animal of the same type mate. That’s male and female chicken and goat.
After mating, the female chicken (ducks, pigeons, etc.) lay eggs. These eggs later hatch into
young once.
In other animals like goat, dogs, sheep, cows, etc., after male and female mate, the female carries
pregnancy and later gives birth to the young animal alive.

Life in both plants and animals begin when a male meets a female to produce their young
ones.
Both the male and the female parts of plant are in the flower.
AGENTS OF POLLINATION
Agents of pollination Pollinating agents are –
1. animals such as insects, birds, and bats
2. water
3. wind
4. Insects and Winds are the major types of pollination.
5. Man
PROCESS OF POLLINATION
Pollination is the transfer of pollen from Anther to Stigma of a flower.
The process of pollination is called fertilization.
Fertilization is the joining together of the male part of the pollen to the female ovules in the
ovary.
The male part of a flower must first join with the female part.
Pollen contains the male part.
The female egg cell is inside the ovule. When the male and female parts join, we say fertilization
has taken place.

PRESENTATION
LEARNING ATIVITIES:
STEP 2: Takes pupils for a walk within and around the school to collect the available common
flowers.
STEP 3: Pupils’ activities bring flowers to the class, Identify and name each of the flower
collected.
STEP 4: Provides sample of flowers like hibiscus and guides the pupils to identify parts of a
flower. Or chart showing parts of flower.
CONCLUSION
EVALUATION
1. identify parts of a flower.
2. draw and label parts of a flower.
3. identify parts of flower that produce fruit.
4. explain the meaning of pollination.
5. state 2 types of pollination.
