ENTRY BEHAVIOUR

Pupils have previously learned about the importance of keeping the environment clean and caring for their surroundings.

This lesson builds on that knowledge by helping pupils understand that the quality of the environment can be healthy or degraded, and that human activities can either improve or damage the environment.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Pictures of clean and dirty environments

2. Waste bins and refuse materials

3. Charts showing environmental pollution

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 everything around us such as land, air, water, plants, and animals. The quality of the environment affects human health and living conditions.

A good and clean environment helps us to stay healthy, while a dirty and polluted environment can make people sick.

In this lesson, we will learn about environmental quality, healthy environment, degraded environment, and how to improve the environment.

LESSON 1 – MEANING OF ENVIRONMENTAL QUALITY

Environmental quality is the condition or state of the environment in relation to how clean, safe, and healthy it is for living things.

HEALTHY ENVIRONMENT

A healthy environment is a clean and safe environment that supports good health and living.

LESSON 2 – DEGRADED ENVIRONMENT

A degraded environment is an environment that is dirty, polluted, and unsafe for living things.

Disadvantages of a Degraded Environment

1. It causes diseases and infections.

2. It leads to poor air and water quality.

3. It makes living conditions uncomfortable.

4. It kills plants and animals.

5. It reduces quality of life.

LESSON 3 – FACTORS THAT DEGRADE THE ENVIRONMENT

1. Improper waste disposal.

2. Air pollution from vehicles and industries.

SUMMARY

In this lesson, pupils learned that environmental quality is the condition of the environment in terms of cleanliness, safety, and health.

They also learned that a healthy environment is clean and safe, and it helps to:

Promote good health

Reduce diseases

Provide fresh air and clean water

Support plants and animals

Pupils further learned that a degraded environment is dirty, polluted, and unsafe, and it can cause:

Diseases

Poor living conditions

Death of plants and animals

Environmental problems

Finally, they identified ways to improve a degraded environment such as proper waste disposal, tree planting, pollution control, and regular cleaning of surroundings.
