Hello, young learners! Welcome back to Basic Science and Technology, Physical and Health Education. In our previous lesson, we learned about environmental health. Today, we’re going to learn about the meaning of noise, air, water, and chemical pollution.
Objectives
By the end of this lesson, you should be able to:
- Define noise, air, water, and chemical pollution.
- List the causes of different types of pollution.
- Appreciate the importance of a clean environment.
- Discuss the effects of pollution on the community and suggest preventive measures.
Meaning of Noise, Air, Water, and Chemical Pollution
Pollution is the introduction of harmful substances or products into the environment. It can be of different types, and some of these include:
Noise
