🔋 Part 1: Circuit Components and Symbols

1. Match each circuit component to its correct symbol by drawing lines:

Battery

Light bulb

Switch (open)

Wire

—————

⚬

—| |—

—||—

2. Which of these makes a complete circuit?

A circuit with a gap in the wire

A circuit with an open switch

A circuit with a closed switch connecting all components

A circuit with no battery

3. Tick all the components you need to make a simple circuit:

Battery

Wires

Light bulb

Motor

Switch

✏️ Part 2: Drawing Circuit Diagrams

4. In the box below, draw a simple circuit diagram showing a battery, light bulb, and switch (closed) all connected with wires. Use the correct symbols.

5. Explain the difference between an open circuit and a closed circuit:

Open circuit: _________________________________________________

Closed circuit: ________________________________________________

6. Complete this sentence:

Electricity can only flow through a circuit when the circuit is _____________ and all components are properly _____________.

7. Look at your circuit diagram in question 4. What would happen to the light bulb if you opened the switch? Explain why.

🔬 Part 3: Circuit Assessment and Extension

8. Self-Assessment: Check your circuit diagram from question 4. Tick if you included:

Correct battery symbol

Correct light bulb symbol

Correct switch symbol (closed)

All components connected with lines (wires)

No gaps in the circuit

9. Peer Assessment: Swap with a partner. Does their circuit diagram meet all the criteria above? Give them one positive comment and one suggestion for improvement:

Positive comment: _________________________________________

Suggestion: ____________________________________________

10. Extension Challenge: Research and draw a diagram showing TWO light bulbs connected in series (one after the other). What do you think would happen if one bulb was removed?

11. Real Circuit Check: After building your circuit, tick what happened:

Light bulb lit up when switch was closed

Light bulb turned off when switch was opened

Circuit worked as expected

Had to troubleshoot problems
