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 create a biosphere in a baggie.

Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?

Does yeast breathe? Find out by watching how plastic bags filled with yeast, warm water and different amounts of sugar change over time.

This is an activity about Newton's First Law of Motion - a body in motion tends to stay in motion, or a body at rest tends to stay at rest unless acted upon by an outside force.

This is an activity about turbidity, or the amount of sediment suspended in water.

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

This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.

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

In this activity exploring liquid dynamics, learners design and build a clay channel in a tray of water and then see what happens when food coloring and liquid soap are added to the mix.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

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 discover why there are holes in bread.

Don't scream for ice cream -- make it with milk, sugar, flavoring and some 'salt-water' ice. Discover the chemistry of ice cream by creating your own.
