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

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

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

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