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

In this physics activity, learners conduct two experiments to explore free-falling.

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

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 will discover why there are holes in bread.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this activity, learners make their own heat waves in an aquarium.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this physics activity, learners will explore buoyancy.

In this experiment, learners float colored ice cubes in hot and cold water.

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

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 activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

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

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.
