1. Experiment Design: Your friend Bob hypothesizes that the way electric circuits work is the following: Positive charges flow out of the + side of the battery while negative charges flow out of the - side of the battery. They flow in opposite directions through the wire until they meet at the light bulb. When they reach the light bulb, the + and - charges annihilate each other, creating light in the process. Describe a testing experiment you could design to convince Bob his hypothesis is wrong. In addition to clearly describing the experiment, predict how the experiment would turn out if Bob's hypothesis were true.
