Gravity Rules!

Recently in science, we have been learning about a noncontact force called gravity. In this experiment, we used the force of the air from a hair dryer to overcome the force of gravity.  At the point where the two forces (gravity and the air) balanced, the ball "floated" in the air.
Words you should know: 
force- a push or pull
mass- the amount of matter that in in an object
weight- the affect of gravity pulling on a mass
gravity- a noncontact force that pulls objects towards one another
