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.

 

HOW SOILS ARE FORMED (OR PROCESS OF BREAKING DOWN OF ROCK) 

This can be a physical, chemical or biological process:

  1. Physical process – This process involves breaking down of rock as result of changes in temperature, abrasion and frost.
  2. Chemical process – This process involves breaking down of rock by chemical makeup. That’s mineral content of the rock with water, air or other chemicals.
  3. Biological process – This process involves breaking down of rock by living thing. Man, animals and micro organisms.

 

FACTORS OF SOIL FORMATION

  1. Parent material – rock
  2. Living organisms – Plants and animals.
  3. Climate – Rain, temperature, air, etc.
  4. Topography – Erosion, drainage and disposition.
  5. Time – duration.

 

 

PRESENTATION

  • To deliver the lesson, the teacher adopts the following steps:
  1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;
  2. Guides the pupils in discussing formation of soil;
  3. Pupil’s Activities – Take active in part in discussing formation of soil.
  4. Demonstrates how man involved in breaking down of rock;
  5. Pupil’s Activities – List various activities of man that aids formation of rock.
  6. Give a board summary.
  7. Pupil’s Activities – Copy board summary.

 

 

CONCLUSION

  • To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
  • Next Lesson – Properties of Soil (Primary 4)
  • Next Lesson – Agents of Soil Formation (Primary 5)
