Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.
