LEARNING OBJECTIVES 

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

1. Explain the meaning of energy.

2. Identify different forms of energy.

3. State uses of energy in daily life.

4. Give examples of energy in their environment.

5. Appreciate the importance of energy.

ENTRY BEHAVIOUR

Pupils have previously learned about vehicles and how they are used for transportation.

This lesson builds on that knowledge by helping pupils understand that energy is needed for vehicles and other machines to work. Without energy, vehicles cannot move and many daily activities cannot be carried out.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Torch light

2. Battery

3. Candle

4. Pictures of sun, wind, car, stove, generator

5. Charts showing forms of energy

METHOD OF TEACHING

Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

SUMMARY

In this lesson, pupils learned that energy is the ability to do work.

• They also learned the different forms of energy, which include: Heat energy, Light energy, Sound energy, Electrical energy, Chemical energy and Mechanical energy

• Pupils were also taught that each form of energy has different uses and examples in everyday life, such as cooking (heat energy), lighting (light energy), communication (sound energy), powering appliances (electrical energy), energy from food (chemical energy), and movement (mechanical energy).

Overall, the lesson helps pupils understand that energy is very important in all daily activities and cannot be done without.
