In order for electricity to travel to where we need it, there must be a complete circuit of electrcity. A complete circuit is like a circle.
Electricity starts at a particular place, travels around the circuit, and returns to the same place.
Ask an adult to help you with this experiment. Tape one free wire end to each end of the battery. In this experiment, the complete circuit is something like the electrical distribution system that brings electricity to our homes. The battery produces the electricity like the generating plant does.
