CONTENT OF THE LESSON
INTRODUCTION
The process of soil formation is called weathering.
Weathering is the breaking down of rocks into smaller (tiny) particles to form soil.
FORMATION OF SOIL
Soil formation is the break down of rocks into smaller particles to form soil.
Rocks are parent materials through which soils are formed.
Soils are formed by the interaction of the following with the parent materials (rocks) –
1. Rain
2. Temperature
3. Wind
4. Man
5. Animals

1. Revises the previous lesson based on the previous lesson or pupil’s knowledge.
2. Displays charts showing different agent of soil formation.
3. Lets pupils recognise and identify the activities of these agents in soil formation.
4. Takes pupils out to observe some of theses agents and describe their activities in soil formation.
Pupil’s Activities – Participate actively in the field activities.
3. Demonstrates how man involved in breaking down of rock;
