THIRD TERM  

WEEK 10

PRIMARY 5

THEME – YOU AND ENERGY 

PREVIOUS LESSON – Basic Electricity I – Electricity As A Form of Energy and Types of Electricity (Primary 4)

TOPIC – BASIC ELECTRICITY 

LEARNING AREA

1. The flow of Electric Current

2. Conductors and Non. Conductors

PERFORMANCE OBJECTIVES 

By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor) and should be able to –

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

Electric Circuit

 

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.

CONTENT OF THE LESSON  

LESSON ONE – INTRODUCTION

Electricity is very useful at home, offices, in school, etc. Most of our home appliances depend on electricity. For example, if there is no electricity, the following items will not work – television set, water heater, etc.

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.)

These energy can be produced by and friction, magnets and chemicals.

 

CONDUCTORS AND NON CONDUCTORS – PUPIL’S ACTIVITIES 

Pupil’s Activities 3

Guides the pupils set up the battery, bulb and copper wire so that the bulb lights.

Lets them replaced the wire with thread and asks them – Does the bulb light for each of them?

Asks the pupils to do the same with each of the materials you have collected, one at a time.

Does the bulb light for each of them? Tick the box if the 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. 

 

MEANING OF CONDUCTORS AND NON CONDUCTORS 

Conductors are materials that allow energy (current) to flow through them. For example, wire, iron, pin, spoon, etc. They are called electric conductors.

While,

Non conductors are materials that do not allow energy (current) to flow through them. For example, paper, broom, thread, cloth, etc.

 

LESSON TWO – MEANING AND COMPONENTS OF ELECTRICAL CIRCUITS

In activities 2 – Basic Electricity I, the pupils arrange a battery or batteries, wire and bulb to give light. The arrangement is called electric circuit.

Electric circuit contains three (3) components:

1. Source – batteries

2. Electric conductors – wire

3. Resistor – the switch (on/off)

 

Note – When you let the pupils realise that the activities 2 is called electric circuit, they will be able to define electric circuit and state its components. 

 

USES OF ELECTRICITY

Electricity is an essential part of modern life and people use 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.

 

Note – Gives the pupils a hint and allows them to start other uses of electricity. 

 

LESSON THREE – WEEKLY ASSIGNMENTS

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. Provides a variety of materials and guides pupils to produce electricity, sort materials into conductors and non conductors, make an electric circuit.

Pupil’s Activities – Use the materials provided to produce electricity.

4. Uses electric circuit to demonstrate that it can light bulbs, make magnets or magnetic field, generate heat.

Pupil’s Activities – Follow the lead to produce electricity and generate heat (bulbs).

5. Guides pupils to complete an electric circuit.

Pupil’s Activities – Follow the teacher’s guidelines to complete an electric circuit by add resistor (switch).

 

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 

Pupils to:

1. group materials into conductors and Non conductors (insulators) of electricity.

2. use the materials provided to complete an electric circuit.
