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.

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.
