Round and Round

After reviewing that objects move because of a force (a push or a pull), PreK scientists continued their study of motion with a lab about things that move in a circular path.

We observed Euler’s Disc. The chrome plated steel disk is 1/2 inch thick and three inches wide. The disk spins on a concave mirror base. The action of the disk is called spoiling which means rolling and spinning. Just give it a twist and gravity does the rest. Will it ever stop? Click here to watch it in action. Fascinating!

So much fun to watch the movement of a flow ring. Click here to learn more.


After reading the story, Squiggle, we used ribbon dancers to mimic the character in the story. We moved them fast and slow, above and below our heads, and into a variety of shapes.
