The generated electricity travels through wires. Demonstrate using a battery, copper wire, and small bulb. Allow the children to experiment with them. Be sure to stress the fact that they will not be shocked by the battery and bulb, but they should not touch electrical parts. When we plug our appliances in a socket, we are connecting wires for electricity to move.
Electricity moves well through wires and water.
It won't move through things like plastic or wood. That is why all electrical appliances have their wires wrapped in a plastic cord, so the electricity cannot get out. Now you know how electricity travels through wires in cords and sockets. Electricity also travels through water. That is why we must be very careful around plugs, cords, sockets, and water.
