CONTENT OF THE LESSON  

LESSON ONE – INTRODUCTION

In the school and at home, we see many moving things. We move about on our legs, vehicles move on roads, trains on the rails, aeroplanes fly in the sky and ships sail on the seas.

Movement occurs when a force is applied on a thing or object. That is, force causes things to move.

It can also prevent things from moving.

MEANING OF FORCE

A force is a pull or push on a object. That’s, force opposed movement or causes objects to movement. For example, car’s accelerator and break or to change direction (steering).

TYPES/EXAMPLES/EVIDENCE OF FORCE

There are many types of forces, but only five are discussed below:

1. Muscular Force

2. Gravitational Force

3. Magnetic Force

4. Electrical Force

5. Frictional Force

 

LESSON TWO – DEMONSTRATING DIFFERENT TYPES OF FORCE

EFFECTS OF FORCE

A force acting on an object may cause the object:

1. to change shape and size.

2. to start moving.

3. to stop moving.

4. to accelerate or decelerate.

LESSON THREE – WEEKLY ASSIGNMENTS 

As stated in 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. Shows the effects of force for pupils to observe.

Pupils’ Activities – Play with springs, magnets, batteries, rubber bands etc. to demonstrate the existence of force.

Pupils’ Activities – Describe the effect of force.

3. Guides pupils’ activity on force.

4. Pupils’ Activities – Push things in the class.

CONCLUSION

• To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson (frictional force).

• Next Lesson – Meaning and Effects of Frictional Force (Primary 6)

LESSON EVALUATION

Pupils to:

1. define force.

2. give three examples of Force.

3. describe the effect of force on materials.
