Moving Molecules

Moving Molecules
Science Demonstrate how heat energy affects the movement of molecules by filling two identical, clear glasses with the same amount of water. Use cold water in one glass and hot in the other. Add two drops of food coloring to each glass. Observe how quickly the color spreads throughout. Which water colors faster, cold or hot? What does this tell us about how heat affects the molecule movement?

In Soda Bottle Science John Cowens' offers a fun experiment that uses a common two-liter plastic bottle as a miniature science lab.
