Harness the Forces of Gravity!

We went to the marble run center at Stringtown Park.
We thought about how we could control the marbles with our materials.
We built structures to support our marble run tracks.
We dropped the marbles onto the tracks and watched gravity take over.
Sometimes we lost control of our marbles.
We had to make adjustments to keep the marbles on the tracks.
