Science: Rolling Spheres

The past few weeks in science, we have been exploring the properties and causes of force, motion, and balance.  After doing several experiments with how to balance objects using counterweights, we did an experiment about how spheres roll using foam runways, marbles, and tape.  We explored the different ways we could make our marbles travel depending on how we varied the position of our ramp(s).  We had a great time!
