THEME – CONSERVATION PRINCIPLES

TOPIC 2 – CONVERSION OF ENERGY

INSTRUCTIONAL MATERIALS

Cells/batteries, bicycle dynamo, solar panels, electric torch.

LEARNING OBJECTIVES

By the end of the lesson, students should be able to:

1. identify the different forms of energy and state how these forms of energy can be converted from one form to another.

2. use simple devices to convert one form of energy to another.

CONTENTS OF THE LESSON

FOCUS LESSONS 

1. Conversion of:

• mechanical energy to electrical, heat, sound energies, etc.

• electrical energy to heat, mechanical light energies, etc.

• radiation energy to electrical, heat energies, etc

• chemical energy to electrical, mechanical energies (vice versa), etc.

2. Devices used is energy conversion in (1) above.

LESSON PRESENTATION

TEACHER’S ACTIVITIES

The teacher demonstrates energy conversion using bicycle dynamo, cells or batteries, solar panels, etc.

 

 

STUDENT’S ACTIVITIES

The students,

1. convert mechanical energy to heat by rubbing hands against one another.

2. convert chemical energy to electrical energy by using cells.

3. convert radiation energy into heat by placing a black metallic surface under the sun.

 

LESSON EVALUATION

Students to,

1. mention the different forms of energy.

2. mention devices that are used to convert energy from one form to another.
