In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

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 sublimate dry ice and then taste the carbon dioxide gas.

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

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

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.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

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

In this activity, learners will discover why there are holes in bread.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

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 chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.
