Electrical Circuits Investigation
⚡ Part 1: Circuit Components Knowledge
1. Circle the components needed to build a complete electrical circuit:
Battery
Wires
Bulb
Plastic spoon
Switch
Rubber band
2. What happens when a circuit is broken?
The bulb lights up brighter
The bulb stops working
The battery gets hot
Nothing changes
3. Fill in the blanks about electrical circuits:
Electricity flows through a _____________ circuit. A _____________ provides the energy, and _____________ connect the components together. A _____________ can stop or start the flow of electricity.
🔬 Part 2: Conductors and Insulators Investigation
4. Record your investigation results in the table below:
5. Based on your investigation, which materials are conductors?
Metal paperclip
Plastic spoon
Aluminium foil
Rubber band
String
Copper wire
6. Why are insulators important for electrical safety?
📊 Part 3: Data Recording and Patterns
7. Draw a labelled diagram of your working electrical circuit. Include all components and use proper circuit symbols if you know them:
8. What pattern did you notice about materials that conduct electricity?
9. Match the circuit component with its function:
1. Battery
2. Switch
3. Wires
4. Bulb
A. Converts electrical energy to light
B. Provides electrical energy
C. Carries electrical current
D. Controls the flow of electricity
🤔 Part 4: Reflection and Further Investigation
10. What problems did your group encounter while building circuits? How did you solve them?
11. Predict what would happen if you added a second bulb to your circuit:
Both bulbs would be equally bright
Both bulbs would be dimmer than one bulb alone
Only one bulb would light up
The battery would stop working
12. List three examples of electrical circuits you can find at home:
13. What new questions do you have about electrical circuits that you would like to investigate further?
14. Why is it important to use low voltage batteries in our investigation rather than mains electricity?
