Recently, sixth grade students made two different recipes for fake snow. The first one used 1 cup cornstarch and 1 cup shaving cream mixed together (glitter and food coloring optional).
The students noticed it was more like a soft play dough when it is made.
The second recipe for fake snow was 2 1/2 cups baking soda and 1 cup white hair conditioner. Glitter and food color optional.
The students had to predict what they thought would happen with the mixtures. They also had to hypothesize which fake snow would be more like real snow.
The second recipe was more like real snow because it went through a chemical reaction, called an endothermic reaction, which made it cold to the touch unlike the playdough version.
