Water Experiments: Matter on the Move

Yesterday the class did an experiment called Matter on the Move from Inquiry in Action. They were excited to see what happens when food coloring is placed in different temperatures of water. They observed what was happening and wrote down what they saw. The students then made a hypothesis about what they thought was happening within the water. Some of the key words they used included heat, temperature, energy, and molecules. Check out the photos. Can you guess which cup shows the reaction of the food coloring with the hot water versus the cold water?
