In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

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 explore density and buoyancy as they design and construct rafts.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

In this activity, learners will build an air cannon out of simple materials you can find around the house. Although air is invisible to the eye, it is not by any means empty space!
