LEARNING OBJECTIVES

By the end of the lesson, pupils should be able to:

1. Explain the meaning of land pollution and noise pollution.

2. Identify sources of land pollution.

3. Identify sources of noise pollution.

4. State the effects of land and noise pollution.

5. Mention ways of controlling land and noise pollution.

ENTRY BEHAVIOUR

Pupils have previously learned about environmental quality and how erosion affects the environment.

This lesson builds on that knowledge by helping pupils understand that human activities such as improper waste disposal and excessive noise can also pollute the environment and make it unsafe for living things.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Pictures of dirty environments and waste dumps

2. Audio recordings of noise pollution (vehicles, markets, loud music)

3. Charts showing pollution types

4. Blackboard/whiteboard

METHOD OF TEACHING

Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON

INTRODUCTION

The environment is where we live, learn, and play. It includes the land, air, water, plants, and animals. Sometimes, human activities make the environment dirty or noisy.

When the land is filled with waste materials or when there is too much noise around us, the environment becomes harmful to health.

In this lesson, pupils will learn about land pollution and noise pollution, their sources, effects, and how to control them.

LESSON 1 – MEANING OF LAND POLLUTION

Land pollution is the contamination of the land by waste materials such as refuse, plastics, chemicals, and other harmful substances.

Sources of Land Pollution

1. Improper waste disposal

2. Industrial waste

3. Plastic waste

4. Oil spillage

5. Agricultural chemicals

Effects of Land Pollution

1. Causes diseases

2. Makes the environment dirty

3. Pollutes water sources

4. Kills plants and animals

5. Produces bad smell

LESSON 2 – MEANING OF NOISE POLLUTION

Noise pollution is unwanted or disturbing sound that affects people and the environment.

Sources of Noise Pollution

1. Loud music

2. Vehicles and traffic

3. Market places

4. Construction sites

5. Loudspeakers and generators

Effects of Noise Pollution

1. Hearing problems

2. Stress and headache

3. Lack of concentration

4. Disturbance of sleep

5. Communication problems

LESSON 3 – CONTROL OF LAND AND NOISE POLLUTION

1. Proper waste disposal

2. Recycling of waste materials

3. Avoiding littering the environment

4. Reducing loud music and noise

5. Using noise control laws

6. Public education on cleanliness

7. Proper maintenance of machines and vehicles

SUMMARY

In this lesson, pupils learned that land pollution is the contamination of land by waste materials such as plastics, refuse, chemicals, and other harmful substances, while noise pollution is unwanted or disturbing sound that affects people and the environment.

They also learned the sources of land pollution, such as improper waste disposal, industrial waste, plastics, and chemicals, and the sources of noise pollution, such as traffic, loud music, generators, and construction activities.

Pupils further learned that land pollution can cause diseases, bad smell, and destruction of plants and animals, while noise pollution can lead to stress, headache, hearing problems, and lack of concentration.

Finally, they learned ways of controlling both types of pollution, such as proper waste disposal, recycling, public education, and reducing unnecessary noise in the environment.
