Electric circuit with bulbs and switches

🎯 WALT: We Are Learning To describe why parts of a circuit might work differently

Success Criteria:

✓ I can explain why a bulb might be dim
✓ I can describe how switches control electricity
✓ I can identify problems in circuits

📚 Part 1: Circuit Knowledge

1. What makes a bulb shine dimly instead of brightly?

The battery is running out

The wires are too long

There are too many bulbs in the circuit

All of the above

2. When a switch is open (off), what happens to the electricity?

It flows faster

It stops flowing

It flows backwards

It gets stronger

3. Which of these could cause a bulb not to light up? (Tick all that apply)

Loose wire connection

Dead battery

Broken bulb

Switch turned off

🔧 Part 2: Circuit Troubleshooting

4. Look at this circuit problem: "The bulb is very dim even with a new battery."

Write two possible reasons why this might happen:

Reason 1: _________________________________________________

Reason 2: _________________________________________________

5. Complete this sentence:

When I press a switch to turn it ON, I am _________________ the circuit so electricity can _________________.

6. Explain in simple words why adding more bulbs to a circuit makes each bulb dimmer:

7. A circuit has stopped working completely. Write down three things you would check to find the problem:

Check 1: ________________________________________________

Check 2: ________________________________________________

Check 3: ________________________________________________

8. Design Challenge: You want to make a torch that can be bright OR dim. Draw and label a simple circuit diagram in the box below that would let you control the brightness.

9. Real-world Connection: Think about the lights in your home. Why do you think some rooms have dimmer switches? Explain your thinking:
