CONTENT OF THE LESSON  

LESSON ONE – INTRODUCTION

Energy is the fundamental need of our everyday life. So much so, that the quality of life and even its sustenance, is dependent on the availability of energy. The Law of conservation of energy even tells us that the only thing that takes place with energy is the transformation from one form to another.

 

MEANING OF ENERGY CONVERSION 

Energy conversion is the changing of one form of energy to another.

FORMS OF ENERGY CONVERSIONS

The forms of energy are electrical energy, heat energy, chemical energy and mechanical energy. These energy can change form to another energy and vice versa as listed below:

1. Mechanical energy can be converted to heat energy.

2. Electrical energy can be converted to heat energy.

For example, pressing iron, electric stove, etc.

3. Electrical energy can be converted to mechanical energy.

For example, blender, electric cooker, etc.

4. Mechanical energy can be converted to electrical energy.

5. Chemical energy can be converted to heat energy.

For example, kerosene stove, etc.

6. Solar energy can be converted to heat energy, chemical energy, and electrical energy.

7. Light energy can be converted to heat energy.

Teacher’s Activities – Demonstrates how one energy can be converted to another. 

LESSON TWO – IMPORTANCE OF ENERGY CONVERSIONS 

The most important of energy is that it can change form. For example,

1. It saves money.

For example, the use of kerosene stove, electric cooker, firewood, for cooking.

2. It reduces pollution.

For example, the use of firewood, kerosene stove, electric cooker and gas cooker.

3. It saves energy.

For example, battery, solar battery, etc.

4. It generates energy.

For energy, solar battery, generator, etc.

5. It replaces non renewable energy.

LESSON THREE – WEEKLY ASSIGNMENT 

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. Discusses the meaning of energy conversion.

Pupil’s Activities – Participate in class discussion.

3. Demonstrates the conversion of energy from one form to another.

Pupil’s Activities – Carry out simple activities on energy conversion.

4. Discusses the importance of energy conversions.

Pupil’s Activities – List the forms and importance of energy Conversion.

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 – Heat and Temperature I – Meaning and Different (Primary 5)

LESSON EVALUATION/ASSIGNMENT 

Pupils to:

1. define energy Conversion.

2. list at least three forms of energy Conversion.

3. state at least three importance of energy conversion.
