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 activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

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, learners use simple items to construct a device for indicating air pressure changes.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

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