Date:

Circuit design with lightbulb and battery

🔌 Part 1: Energy Device Knowledge

1. Which of these is needed for a complete electrical circuit?

Power source, conducting wires, and output device

Only a battery and a light bulb

Just wires connecting components

A switch by itself

2. Select all the materials that are good conductors of electricity:

Copper wire

Plastic coating

Metal paper clip

Rubber gloves

3. What happens when you open a switch in a circuit?

The circuit becomes complete and electricity flows

The circuit breaks and electricity stops flowing

The battery gets stronger

Only the light bulb stops working

4. Fill in the blanks: Energy from a battery travels through _____________ to power devices like bulbs or buzzers. _____________ materials stop electricity from flowing where we don't want it.

🎯 Part 2: Design Your Energy Device

5. Describe a real-world problem your energy device will solve:

6. Draw and label your circuit design below. Include: battery, wires, switch, and output device (bulb/buzzer/LED). Use proper circuit symbols.

7. Explain how energy flows through your circuit to create the desired effect:

8. Plan a fair test for your device:

What will you CHANGE? _________________________________

What will you MEASURE? _________________________________

What will you keep the SAME? _________________________________

🛡️ Part 3: Safety and Reflection

9. List three safety rules for working with electrical circuits:

10. Make a prediction: "If I close the switch in my circuit, then _________________ will happen because _________________________________."

11. How could you improve your device design to make it work better or solve the problem more effectively?

Success Criteria - Tick when complete:

☐ I have drawn a clear circuit sketch with all components labelled

☐ I can explain how energy flows through my circuit

☐ I have planned a fair test with change, measure, and control variables

☐ I have described safety procedures for handling electrical components
