Games: How circuit work?

An electric circuit needs two main things in order to work:
1. A power source.
2. To be complete.
This means that the wires connecting all the objects (switches, light-bulbs, buzzers and so on) must start and end at the power source before the circuit can work. That's why batteries have a top and bottom (+ and -) so they can carry the charge all the way around.

  1. This game very good for kids to understand how the circuits word.
