Virtual Circuit Investigation

Building and Troubleshooting Virtual Electrical Circuits

Part A – Building a Complete Circuit

Use the PhET Circuit Construction Kit as directed by your teacher. Record your predictions, observations and explanations in complete sentences where appropriate

Investigation record: Task | Prediction | Observation | Explanation

1. Task: Build a complete circuit.

Prediction: What do you think will happen when the switch is closed?

Observation: What happened when you built and tested the circuit?

Explanation: How did the components interact to make the globe light?

Components checklist:

Battery    Wires    Switch    Globe

2. Quick sketch or symbol diagram of your working circuit:

Part B – Troubleshooting Circuits

For each fault, observe what happens in the simulation, explain why the circuit does not work, and describe how you fixed it.

Fault | What happened? | Why didn’t it work? | How did you fix it?

3. Fault: Open switch

What happened? Why didn’t it work? How did you fix it?

4. Fault: Disconnected wire

What happened? Why didn’t it work? How did you fix it?

5. Fault: Globe not connected correctly

What happened? Why didn’t it work? How did you fix it?

6. Fault: Battery removed

What happened? Why didn’t it work? How did you fix it?

Part C – Reflection and Part D – Exit Ticket

7. Which fault was the easiest to identify?
8. Which fault was the hardest to fix?
9. What did you learn about complete circuits?

Exit Ticket

10. Explain the difference between an open circuit and a closed circuit.
11. Describe one fault that stopped a circuit from working.
12. Explain how you corrected the fault.

Safety Reminder

Follow teacher instructions and use the ICT simulation appropriately.
