Materials: Toys cars that change color, tub, warm water, cold water, prism
Activity: Dunk cars in cold water, and then in hot water. Did anything change color?
Research Questions: How can you get the cars to change color? Is there a pattern among which colors multiple cars change into? Does a color-change car ever 'wear out'?
