2. The flow of Electric Current

3. Conductors and Non. Conductors

4. Sources of Electricity

5. Component of A Circuit

6. Uses of Electricity

7. Lesson Evaluation and Weekly Assessment (Test)

### PERFORMANCE OBJECTIVES

By the end of the lesson, most of the pupils should have attained the following objectives –

1. explain how electricity travels (conducted) from one point to another

2. group materials into conductors (metals) and nonconductors (wood, glass, plastic).

3. make a simple electric circuit connection.

4. state the uses of electricity.

### ENTRY BEHAVIOUR

The pupils can state the use of electric switch.

### INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of Wool, fur or silk. Hard rubber rod or comb, Glass rod, Dry cell (1.5v), Bar magnets, Nails, pieces of paper, ropes, threads. Light bulbs, Connecting wires, Circuit board, Lamp holders, Switch key, Pins. Bar magnets, Iron fillings, Paper clips, Coins, Rubber bands.

### 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.

### REFERENCE MATERIALS

1. Scheme of Work

2. 9 – Years Basic Education Curriculum

3. Course Book

4. All Relevant Material

5. Online Information

### LESSON 1 – INTRODUCTION

Electricity is a form of energy that can give things the ability to move and work.

Electricity makes the following to work or move: bulbs, torch light, television, toy cars, machines (like cars, etc.)

MEANING OF CONDUCTORS AND NON CONDUCTORS

CONDUCTORS

Conductors are materials that allow energy (current) to flow through them.

For example, wire, iron, pin, spoon, etc.

They are called electric conductors.

NON CONDUCTORS

Non conductors are materials that do not allow energy (current) to flow through them.

For example, paper, broom, thread, cloth, etc.

### LESSON 2 – MEANING AND COMPONENTS OF ELECTRIC CIRCUITS

The connection between batteries and bulb with wire to produce light is called electric circuit.

There are three (3) components of electric circuit,

1. Source – batteries

2. Electric conductors – wire

3. Resistor – the switch (on/off)

USES OF ELECTRICITY

Electricity is an essential part of modern life and people used electricity for the following:

1. Heating and Cooling water.

2. Water Heater

3. Washer and Dryer

4. Lights

5. Refrigerator

6. Electric Oven

7. Dishwasher

8. Decoration – Christmas lights

9. Cooking

10. Operating all our home appliances – television, computer, radio, fan, pressing iron, etc.

11. Operating machinery and public transportation systems.

LESSON 3 – REVISION AND WEEKLY ASSESSMENT (TEST)

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

3. Teacher gives each of the group or pair with the following materials – batteries, bulbs, coppers wire, etc. with the instructions,

• set up the battery, bulb with copper wire to produce light.
• replace the wire with thread, paper strip, aluminium foil, broom stick, pin, nail, stone, etc.
• compare the two records
• Tick the box if the bulb light on or light not on.

Teacher’s remark – All light on materials are called electric conductors or electric carriers. While all light not on materials are called non conductors.

Pupil’s Activities – Follow the teacher’s instructions and tick the box if the bulb light on or light not on.

4. Teacher uses the step 3 to introduce the lesson.

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

5. Teacher leads a discussion on electric flow, conductors and non conductors.

Pupil’s Activities – Differentiate between electric conductors or non conductors.

6. Teacher uses pupil’s activities in step to guide them to identify the component of electric circuit.

Pupil’s Activities – Identify and describe the important of each component of electric circuit.

7. Teacher displays chart showing different devices that cannot work without electricity.

8. Teacher uses the chart to ask pupils to state the uses of electricity in the school, at home and in their communities.

Pupil’s Activities – Identify, state and analyze the importance of electricity in the school, at home and in their communities with appropriate examples.

9. Teacher summarizes the lesson on the board with appropriate examples.

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

CONCLUSION

• To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

LESSON EVALUATION

1. differentiate between electric conductors and non conductors.

2. state 5 examples of the following:

• electric conductors
• non conductors

3. explain the meaning of electric circuit.

4. mention the 3 components of electric circuit.

5. make a simple electric circuit.
