Simple Machines IV - Levers
The lever is an everyday simple machine. Youngsters learn the principles of levers and explore their many uses. Groups of pupils perform a simple lab where they lift objects with a fulcrum while placing the load in a variety of positions. They experiment with how much force needs to be exerted to lift the object based on it's position. The lesson has a lab sheet embedded in it to make implementation quite simple. A good lesson on simple machines!
