Grade 5 Science · World 8: Circuit Works · Level 56
Open and Closed
Predict whether a bulb lights, and flip the switch.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 56
- This circuit is closed. The path is complete, so current flows and the bulb lights.
- Now the switch is open. There's a break in the path, so the current stops and the bulb goes out.
- It sounds backward, but remember: closed means on, and open means off.
- Any break does the same thing, even a gap in a wire.
