CONTENT OF THE LESSON  

LESSON 1 – INTRODUCTION

Soil consists of inorganic particles and organic matter.

Soil provides the structural support to plants used in agriculture.

It is also their source of water and nutrients

 

 

MEANING OF SOIL AND SOIL CONSTITUENTS 

MEANING OF SOIL 

Soil is the top layer of the earth’s surface.

 

SOIL CONSTITUENTS 

Soil constituents are the living and non – living things inside the soil.

For examples –

1. Water

2. Leaf litters

3. Rocks

4. Humus

5. Dead animals

6. Living animals

7. Air

8. Soil particles – sand, loam and clay.

 

 

EXISTENCE OF SOIL CONSTITUENTS 

Materials needed for demonstrating the existence of soil constituents are –

1. filter (to separate the soil from other soil materials),

2. water (to separate the soil from other soil materials. This allows the soil to settle down with other soil materials float), and

3. heat (to make all living organisms come out from the soil). 

 

Teacher’s activities – Guide the pupils to prove the existence of soil constituents.

 

 

LESSON 2 – TYPES OF SOIL

There are three (3) major soil,

1. Sandy soil

2. Clay soil

3. Loamy soil

 

MEANING OF SANDY SOIL 

Sandy soil is the loose parts of the soil used for building of houses and construction of roads.

 

MEANING OF CLAY SOIL 

Clay soil is the solid parts of the soil used for moulding and building of houses.

 

MEANING OF LOAMY SOIL 

Loamy soil is the best parts of the soil used for growing crops.

It combines the good parts of clay and sandy.

 

 

IMPORTANCE OF SOIL

1. It is used for building.

2. It is used for making blocks.

3. It is used for road construction.

4. It is used for agricultural purposes.

5. It is used for moulding.

6. It is used for bridge construction.

7. It is used for design and decoration.

 

 

LESSON 3 – REVISION AND WEEKLY ASSESSMENT 

As state in the performance objectives or lesson evaluation.

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. Take pupils on field to collect soil samples.

3. Uses the soil samples to introduce the lesson and asks pupils to describe the soil.

Pupil’s Activities – Identify, collect soil samples and describe.

4. Organizes the class in groups or pairs and asks pupils to collect soil samples from the school garden and guides them to handpick visible soil constituents.

Pupil’s Activities – Bring samples of garden soil to class and hand pick visible soil constituents like leaf litters, small, rocks, dead and living organisms, etc.

5. Notes all the soil constituents identified on the board and add other soil constituents not available in the available soil samples.

Pupil’s Activities – Write as instructed.

6. Uses the soil samples to guide pupils to examine and identify the colour, texture and particles of each soil sample.

Pupil’s Activities – Identify the colour, texture and particles of each soil sample.

7. Writes the types of soil on the board and leads a discussion on each type.

Pupil’s Activities – Participate actively in the class discussion.

8. Displays chart showing the importance of soil.

9. Lets pupils to study the chart carefully and describe.

Pupil’s Activities – Study the chart, identify and describe the content of the chart.

10. Uses pupil’s responses to lead a discussion on the importance of soil.

Pupil’s Activities – Participate actively in the class discussion and state the importance of agriculture.

11. Summarizes the lesson on the board.

Pupil’s Activities – Participate actively in the summary and write as instructed.

 

 

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 – Growing of Plants – Soil Preparation | Planting and Nurturing of Plants Primary 4/Basic 4 Term 2 Week 4 Basic Science

 

 

LESSON EVALUATION 

Asks pupils to –
