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

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

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

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.

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

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

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

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.
