The boys spent some time experimenting with a rubber band, a marble, and cup. They shot the marble at the cup with the rubber band, and watched to see what the cup did. They tried pulling the rubber band back by different amounts to see how much the cup moved each time. (It was hard to get the aim right, and I think I would like to look for a similar investigation that controls for aim.)
Then, we read and took notes on a handout about energy transfer.
Tomorrow, we will investigate how changing the speed of a marble effects the energy of that marble.
