Simple Machines

Simple machines are all around us. Yet most people eating spaghetti with a fork or turning a doorknob rarely stop to think about just how important devices like levers and wheels really are!

Objects like robots, bulldozers, and bicycles may take center stage in the mechanical world, but the truth of the matter is that six simple machines — in use for literally thousands of years — are far more important in our daily lives. Check out these places on the Internet for wonderful insights into the world of simple machines, plus easy-to-conduct, hands-on activities for students of all ages.
