Crayon Melting Science

Crayons can be used for more than just coloring! Create a fun Valentine's card while learning how different pigments, which give crayons their color, react differently to heat. Crayons with darker pigments, or colors, will melt faster than crayons with lighter pigments because they can absorb more infrared heat, but does this mean they will melt as fast with a hair dryer? Test a variety of colors to see which melt fastest or slowest with some crayon melting science to design your own Valentine's Day card.

Soap Powered Boat

Create your own soap powered boat to travel across the water's surface. Soap is a surfactant, which means it breaks up the surface tension of water. When you put soap on the lightweight boat, the soap breaks up the surface tension on the water with enough force to move the boat forward. Now try out different kinds of soap to see which soap makes the boat go faster!
