Energy Device Construction Worksheet
⚡ Part 1: Circuit Safety and Planning
1. Circle the THREE most important safety rules when building electrical circuits:
Keep hands dry when handling batteries
Never use mains power outlets
Wear safety glasses
Only use high voltage batteries
Handle batteries carefully
2. What is the main purpose of your energy device? What should it do when working correctly?
3. Complete your materials checklist by ticking what you need:
Battery (energy source)
Conducting wires
Switch (control component)
Bulb or motor
Insulating tape
🔧 Part 2: Building and Testing
4. Draw a simple diagram of your completed circuit in the box below. Label the energy source, conductors, switch, and the component that uses energy (bulb/motor):
5. Testing Results - Complete the table after testing your device:
| Switch Position | Does electricity flow? (Yes/No) | What happens to your bulb/motor? |
|---|---|---|
| Switch OPEN | ||
| Switch CLOSED |
6. In your circuit, which materials act as CONDUCTORS (allow electricity to flow)?
7. Which materials act as INSULATORS (stop electricity from flowing where we don't want it)?
🔄 Part 3: Improvements and Reflection
8. What was ONE problem you encountered while building your circuit?
9. Complete this sentence: "When the switch is closed, the circuit is complete, so electricity can flow and _______________"
10. What ONE improvement did you make to your device during testing? Why did you choose this change?
11. How does energy transfer and transform in your working device? Use scientific language to explain.
