• Simple Machines: Background Information, Lessons, and Activities
  Sometimes, students don't realize how much science is all around us every day. For instance, simple machines, which include pulleys, wheels and axles, levers, inclined planes, screws, and wedges, combine to create cars, which are compound machines. By examining each simple machine found in cars, the overall machine becomes less mysterious but even more interesting. Learning about each type of simple machine can help students understand not only how cars work but how many other things work in their world.
