Zap and Flow

Turn a light switch on and off and talk about what electricity does — it powers everything!

Category: Math & Science · Duration: ~5 min

1. Walk to a light switch. "Watch this." Flip it on. "Where did the light come from?" 2. Flip it off. "Where did it go?" 3. "Electricity is like invisible power flowing through wires in the walls. When you flip the switch, it opens the path." 4. Walk around and find other things that use electricity: fridge, TV, clock. 5. Safety rule: "Never stick anything in an outlet. Only plug things go in there, and only grown-ups do that."
