Clip: Special | 9m 9s

In this Science Trek: The Web Show, Host Joan Cartan-Hansen and her guest scientists John Gardner, Boise State University and Kathryn Devine, the College of Idaho, answer more students’ questions about simple machines. A simple machine has few or no moving parts, but because of them, humans have been able to create the wonders of the world: the pyramids, computers, even your jar of peanut butter.
