CONTENT OF THE LESSON  

LESSON 1 – INTRODUCTION

Energy is the fundamental need of our everyday life.

Energy is everywhere around us and takes different forms.

For examples,

  • It can be felt as heat.
  • It is observed with eyes as light.
  • kinetic energy is perceived as force.

The quality of life and even its sustenance, is dependent on the availability of energy.

For example, it takes energy to cook food, to drive to school, and to jump in the air.l, etc.

 

MEANING OF ENERGY 

Energy is the ability of a body to do work.

Work is said to be done when applied force moves a body through a given distance.

Energy is neither created nor destroyed.

Energy is converted from one form to another.

 

FORMS OF ENERGY 

The forms of energy are as follows:

1. Kinetic energy

2. Potential energy

3. Solar energy

4. Light energy

5. Heat enegy

6. Electrical energy

7. Mechanical energy

8. Chemical energy

9. Sound energy

 

 

LESSON 2 – FORMS OF ENERGY

The forms of energy are as follows:

1. KINETIC ENERGY

Kinetic energy is an energy in motion.

It is actively using energy for movement.

For examples,

  • Walking
  • Running
  • Falling
  • Throwing a ball
  • Flying aeroplane

 

2. POTENTIAL ENERGY

Potential energy is the energy stored in a person or object as a result of its position.

When potential energy is released, it becomes kinetic energy.

For examples,

  • The food we eat
  • An orange on a tree branch
  • Air in a balloon before it is released
  • A child at the top of a slide
  • A bottle on a table before it falls

 

SOLAR ENERGY 

Solar energy is the energy that comes from the sun.

For examples,

  • Light
  • Heat

 

3. LIGHT ENERGY 

Light energy is the energy that makes us to see things clearly.

For examples,

  • Sun, moon and star
  • Light bulb
  • Firefly
  • Torchlight
  • Candle
  • Computer screen
  • Firewood light
  • Lighting
  • Traffic light, etc.

 

4. HEAT ENERGY 

Heat energy is an energy transfer between two or more objects.

For examples,

  • The heat from the sun
  • A cup of hot tea
  • Baking in an oven
  • The heat from a pressing iron

 

5. ELECTRICAL ENERGY 

Electrical energy is an energy from electric charger participles.

For examples,

  • Electricity generators
  • Batteries
  • Hydropower
  • Power generating plants

 

6. MECHANICAL ENERGY 

Mechanical energy is the sum of potential and kinetic energy.

For examples,

  • Human body
  • Wind
  • Tide
  • Breathing in and out
  • Hammering a nail
  • Riding a bicycle, etc.

 

8. CHEMICAL ENERGY 

Chemical energy is the energy from chemical reactions between atom or molecules.

For examples,

  • Food
  • Batteries
  • Kerosene
  • Petrol
  • Coal, etc.

 

9. SOUND ENERGY 

Sound energy is the energy that we can hear.

For examples, energy from radio, television, musical instruments are known as sound energy.

 

 

LESSON 3 – USES OF ENERGY

The uses of energy are as follows:

1. It is used for boiling water.

2. It used used for producing light.

3. It is used for entertainment.

4. It is used for cooking.

5. It is used for working.

6. It gives us strength.

7. It makes vehicles go, planes fly, boats sail, and machines run.

 

 

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 organized pupils in groups to test their strengths in a tug of war game.

Pupil’s Activities – Participate actively in the tug of war game.

3. Teacher asks each group to discuss why they win or lost to other group.

Pupil’s Activities – State the reasons for winning or losing.

4. Teacher uses the pupil’s responses to introduce the lesson.

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

5. Teacher lead a discussion on the meaning and form of energy with appropriate chart and examples.

Pupil’s Activities – Examine the chart and identify form of energy to explain the meaning of energy.

6. Teacher guides pupils to identify and state the uses of energy.

Pupil’s Activities – Analyze the importance of energy in the community.

7. Teacher summarizes the lesson on the board with appropriate evaluation.

Pupil’s Activities – Participate actively in the summary of the lesson by responding to the lesson evaluation and write as instructed.
