Does Electricity Flow Better
Through Thick or Thin Wires?

The purpose of my science which light bulb shines brighter. To
project is to find out if electricity do this, I will need materials: 2
batteries, light bulbs, tape and

In the procedure, Iʼm going experiment. In my experiment, the

because the thicker wires give the

brighter if you use thick wires.
