In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

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.

In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

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

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

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

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 activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

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.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

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

Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.
