CONTENT OF THE LESSON  

LESSON 1 – INTRODUCTION

Energy is the ability to get work done.

FORMS OF ENERGY 

The forms of energy are as follows:

1. Mechanical energy

2. Chemical energy

3. Solar energy

4. Heat energy

5. Sound energy

6. Electrical energy

7. Light energy

8. Potential and kinetic energy

IDENTIFICATION OF DIFFERENT FORMS OF ENERGY 

Teacher organizes the pupils in groups or pairs depending on the size of the class and guide pupils to identify each form of energy.

1. Cars need _________ and _________ to work (Engine and petroleum).

The engine is known as mechanical energy while petroleum is known as chemical energy.

Other chemical energy include kerosene, diesel, battery, etc. 

2. To dry a fish or our cloth, we use _________ (sun or fire).

Sun and fire produced heat called heat energy. 

Energy from the sun is known as solar energy. 

3. Speaker produce _________ (Sound).

The sound called sound energy. 

4. Television, radio, etc. need _________ (Electricity).

The electricity is called electrical energy. 

5. Touch light produce _________ (Light).

The light is called light energy.

LESSON 2 – FORMS OF ENERGY

1. POTENTIAL ENEMIES

Potential energy is the energy stored in an object.

2. KINETIC ENERGY

Kinetic energy is the energy that the object to move.

3. MECHANICAL ENERGY 

Mechanical energy is the sum of potential energy and kinetic energy.

4. CHEMICAL ENERGY 

Chemical energy is the energy stored within bond of chemical compound.

For example – battery, kerosene, diesel, etc.

5. SOLAR ENERGY

Solar energy is an energy from the sun.

It produces heat and light.

6. HEAT ENERGY 

Heat energy is a form of energy that is transferred from one object to another.

For example, energy from fire, sun, electric iron, etc.

7. SOUND ENERGY 

Sound energy is a form energy that can be heard by living things.

8. ELECTRICAL ENERGY 

Electrical energy is the energy that make electronic to work.

9. LIGHT ENERGY

Light energy is a kind of energy that has the ability to make different light visible to the eyes.

For example – torch light, bulb, fire, etc.

LESSON 3 – USES OF ENERGY TO MAN

Energy is very important because it used,

1. It is used for cooking, boiling, drying, frying and ironing.

2. It is used for moving from one place to another.

3. It is used for heating and cooling our body or environment.

4. It is used for lighting our environment.

5. It is used to power our electronic or mechanics.

6. It is used for entertainment and communication.

7. It is used for preserving our food and drinks.

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. Teacher organizes the pupils in groups or pairs depending on the size of the class.

3. Teacher sample or chart showing different source of energy.

4. Teacher lets pupils identify and state their uses. For example, the sun is used for drying cloth, etc.

Pupil’s Activities – Identify and state the uses of battery, kerosene, sun, torch light, etc.

5. Teacher uses the sample or chart to introduce the lesson and discuss the meaning and forms of energy.

Pupil’s Activities – Pay attention to the lesson introduction to understand the concept of the lesson.

6. Teacher guides pupils to identify different forms of energy and how they work.

Pupil’s Activities – Demonstrate the usefulness of different energy.

7. Teacher discuss each form of energy with the groups or pairs using appropriate examples.

Pupil’s Activities – Explain each form of energy with appropriate examples.

8. Teacher leads a discussion on the uses of energy to man.

Pupil’s Activities – Analyze the importance of energy in their communities and daily life.

9. Teacher summarizes the lessons on the board with appropriate lesson evaluation.

Pupil’s Activities – Participate actively in the lesson summary by responding correctly to the questions and writes as instructed.
