Date:

Simple circuit with battery, wires and light bulb

🔋 Part 1: Circuit Knowledge

1. Circle the things you need to make a simple circuit:

Battery

Apple

Wires

Light bulb

Book

2. What happens when electricity flows through a conductor?

The light bulb lights up

The light bulb stays off

The battery breaks

3. Fill in the blanks:

A _____________ lets electricity flow through it.

An _____________ stops electricity from flowing through it.

🧪 Part 2: Testing Materials

4. Test each material in your circuit. Tick ✓ if the bulb lights up, Cross ✗ if it doesn't:

Metal spoon: _______ Is it a conductor or insulator? _____________

Wooden stick: _______ Is it a conductor or insulator? _____________

Plastic ruler: _______ Is it a conductor or insulator? _____________

Rubber eraser: _______ Is it a conductor or insulator? _____________

Aluminium foil: _______ Is it a conductor or insulator? _____________

5. Which materials made the light bulb turn on?

6. Draw your circuit below. Label the battery, wires, and light bulb:

🏠 Part 3: Real Life Connections

7. Why do electrical wires have plastic covering around them?

To make them look pretty

To keep us safe from electricity

To make them heavier

8. Think of one conductor and one insulator you use at home:

Conductor: _________________________

Insulator: _________________________

9. Challenge: Predict what would happen if you tested a paper clip. Explain your thinking:
