Zoomers & Roller Coasters


Our class made "zoomers" to show that we know how spinning objects use an axis!
It was hard work!













We also made roller coasters out of foam tubes and a marble.
We made loop-de-loops, hills, dips, and spirals!
Gravity keeps the sphere rolling toward the ground, and if you have enough force, the sphere can move up the track!
