WHAT DO MACHINES DO FOR YOU AND ME?
We discovered that machines make work much easier. We even built a machine with levers.
WE BUILT CATAPULTS!!
We used levers to make a catapult. Do you know what a lever is?
Is a lever a simple machine or a complex one?
How do you know?
We discovered that catapults can launch an object a great distance!!!
