In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

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

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

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

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

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

This activity offers learners and their families several ways to raise their awareness together about home water.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

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

In this activity, learners discover how solar energy can be used to heat water.
