__Simple Machines and Levers__ ** Lever, pully,wheel&axle,inclined plane ,wedge,screw,fulcrum.
 * Let's learn about:
 * Watch this short video about simple machines:** []
 * What are the six simple machines? **


 * Go to this link to see a short video about levers: ** []
 * Do your experiments, then answer these questions: **

suport point
 * What is a fulcrum?**

** Fulcrum close to effort ** **Fulcrum close to load

When you push or pull down on a lever are you providing the force or the load?** force.

it is easyer closer to the books.
 * If you are using a lever to lift a stack of books, is it easier if the fulcrum is close to the books (load) or if it is farther away? **
