In this lesson, students use previous knowledge about friction to formulate hypotheses concerning the effects of weight and contact area on the amount of friction between two surfaces. In the Associated Activities (Does Weight Matter?...

Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if the amount of area over which an object contacts a surface it is moving...

Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if weight added incrementally to an object affects the amount of friction...

This is an experiment that will allow observation on how friction will make a ping pong ball curve when it is thrown into the air.
