What happens when a chemical change takes place?

The equation for the change in the position of a train (measured in units of length) is given by the following expression: x = ½ at² + bt³ where a and b are constants and t is time (measured in units of time).

Sully uses a battery and a coil of wire to create an electromagnet. Using the same materials, if he wants to increase the strength of his electromagnet, he must the number of loops in the coil of wire along its length.

The boys tried a second experiment. They built a balloon car like the one seen here. As the gas in the balloon is released, the car moves. Ben and Dylan discovered that the bigger they blew up the balloon, the farther the car moved.
