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 explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

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 conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

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 activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

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 build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

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

In this demonstration, learners observe as two cola bottles and a dollar bill are arranged in a specific order: one bottle, upside down and filled with water, is placed on top of another bottle, with

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

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

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.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this activity, learners use sieves with different-sized holes to sort balls by size.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.
