In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

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

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

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.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

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

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

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

April showers bring May flowers, but what do coastal storms bring?

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

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

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this multi-part activity learners examine non-point water pollution.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.
