Levers

Is a long bar that is balanced on something underneath. 

The Fulcrum is the part underneath. By pushing one part of the bar down the other goes up on the fulcrum. The closer the fulcrum is the easier it is to lift the object. 


Are used to push heavy loads up and down.

Other objects can be leavers to!
