THEME – YOU AND ENERGY
PREVIOUS LESSON – Heat and Temperature II – Units and Symbols of Temperature Scale (Primary 5)
TOPIC – BASIC ELECTRICITY
1. Electricity as a Form of Energy
2. Types of Electricity
3. Cell or Battery and the Flow of Electric Current
By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor) and should be able to –
1. identify types of electricity.
2. explain how electricity is produced (generated) and used.
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.
1. Scheme of Work
2. 9 – Years Basic Education Curriculum
3. Course Book
4. All Relevant Material
5. Online Information

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 AS A FORM OF ENERGY
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.
TYPES OF ELECTRICITY
There are two types of electricity – static and current electricity.
LESSON TWO – STATIC ELECTRICITY AND ELECTRIC CURRENT
Pupil’s Activities 1
Asks each of the pupils in groups to rub their biro case on the sleeve of their shirt vigorously and quickly, and bring it near a small piece of plain paper.
Asks them, what is your observation?
Pupil’s observations – There is an attraction between biro case and the small piece of plain paper.
Teacher’s remark – Tells the pupils that, the attraction is caused by static electricity. This is one of the types of electricity.
Pupil’s Activities 2
Lets the pupils use a battery and wire to light a bulb. Asks their observation, when the wire is connected or disconnected from the battery.
Asks them the following questions:
1. what happens when a torch light is switched on and off?
2. What happens when a television wire is removed from the socket?
Pupil’s observations (excepted respond) – when bulb goes off. The same happened when you switched off a torch light. But when you put it on, it gives light.
The television starts working when connected and stops working when disconnected.
METHODS OF GENERATING ELECTRICITY
Electricity generation is the process of generating electrical power from other sources of primary energy. Electricity can be generated using the following:
1. Hydro (water) – Kainji dam
2. Solar (sun)
3. Machines (generator)
LESSON THREE – WEEKLY ASSIGNMENTS
As stated in performance objectives or lesson evaluation.
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. Guides pupils to produce electricity from friction, magnets and chemicals.
Pupil’s Activities – Rub wool materials firmly on a hard rubber rod or comb and move the rod close to small pieces of paper or pins. Note what happens.
3. 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).
- To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
1. name types of electricity.
2. describe how electricity is generated and conducted from one point to another.
3. group materials into conductors and Non conductors (insulators) of electricity.
4. use the materials provided to complete an electric circuit.
