How can you tell they’ve got it: How switches work?

If they’ve got it, you’ll see things like: Explain that a closed switch completes the circuit (current flows) and an open switch breaks it (current stops); Demonstrate adding a switch to a circuit and using it to control a bulb or buzzer; Relate the switch concept to everyday switches in the home. Or just try it together: Can your child explain what happens inside the wall when they flip a light switch — that it completes or breaks the electrical loop?

How switches work

Your child knows a switch turns a light on and off by closing or breaking the circuit loop. A closed loop lets the electricity flow; a gap stops it.

In curriculum terms

Recognise that a switch opens and closes a circuit, controlling whether a lamp lights or a buzzer sounds
