Jessie Rack: Science will Save the World - Keep on Rockin' in the Rock Cycle

This week is all about the rock cycle: the natural process of rocks being turned into other kinds of rocks.

In this video, I demonstrate the rock cycle using crayons – and you can too! (Provided you have the right materials and a grownup-aligned person to do the oven part.) Grab your favorite rocks and least-favorite crayons and let’s get rockin’!
