# Orbiting Marbles

##### This Orbiting Marbles activity & project also includes:

Using easily obtained materials, physical science beginners are exposed to Newton's first law of motion. They see that a marble will roll in a straight line unless something forces it to change directions, in this case, the rim of a paper plate. Be aware that for older learners, the comparison of this motion to the orbit of the space shuttle is inaccurate since a push keeps the marble in circular motion, whereas orbit is caused by gravitational pull.
