In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

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 sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this activity, learners will explore the density of an object in water. Learners will compare what happens to fruits and vegetables in regular and salt water.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

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

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.
