Simple Machines

I enjoyed this assignment.

I learned that a bathtub is an incline plane. I learned that a stapler has a lever and a wedge. I think pulley's are cool. I like how the pulley was used to lower the TV out of the ceiling.

What I don't understand is how a ceiling fan and a propeller on a boat are incline planes.

I thought this game was alot of fun!!
