WEEK 6

SUBJECT: Basic Science

TOPIC: Electrical Energy

CLASS: JSS 1

DURATION: Two Periods (40 minutes each)

PERIOD 1 – LEARNING OBJECTIVES

By the end of the lesson, students should be able to:
i. Define electrical energy
ii. Identify common sources of electrical energy
iii. State the uses of electrical energy

KEY VOCABULARY WORDS

Electricity, Energy, Circuit, Fuse, Circuit breaker, Resistor, Series, Parallel

RESOURCES AND MATERIALS

Dry cell batteries, connecting wires, small bulbs, fuse wire, switch, chart of circuits

BUILDING BACKGROUND

The teacher asks students:

  • What do we use electricity for at home?
  • What happens when there is no power?

The teacher explains that electricity is a form of energy that helps us do work like lighting, cooking, and using machines.


CONTENT

PERIOD ONE

Meaning of Electrical Energy

Electrical energy is the energy produced by the flow of electric current.

It is the energy that makes bulbs light, fans move, and radios work.

Sources of Electrical Energy

  • Battery
  • Generator
  • Power station
  • Solar panel

Uses of Electrical Energy

  • Lighting
  • Heating
  • Cooking
  • Running machines

WEEK 6

SUBJECT: Basic Science

TOPIC: Electrical Energy

CLASS: JSS 1

DURATION: Single Periods (40 minutes each)

PERIOD 2 – LEARNING OBJECTIVES

By the end of the lesson, students should be able to:
i. Identify the difference between series and parallel connections
ii. Explain the function of a fuse
iii. Explain the function of a circuit breaker

PERIOD TWO

Series and Parallel Connections

Series Connection:
In a series connection, components are connected in one line.
If one bulb goes off, all go off.

Parallel Connection:
In a parallel connection, components are connected in separate paths.
If one bulb goes off, others still work.

Fuse

A fuse is a safety device that melts when too much current flows, stopping electricity to prevent damage.

Diagram Of A Fuse 

Circuit Breaker

A circuit breaker is a safety device that automatically switches off electricity when there is too much current.

Difference Between Fuse and Circuit Breaker

Fuse Circuit Breaker
Melts to stop the current Switches off the current
Must be replaced Can be reset
Used once Used many times

WRAP UP & ASSESSMENT

  1. What is electrical energy?
  2. What happens in a series connection when one bulb goes off?
  3. State one function of a fuse.

ASSIGNMENT

  1. Write two uses of electrical energy.
  2. Differentiate between a fuse and a circuit breaker.
