Using simple, inexpensive items, learners build and test submarine models.

In this quick activity, learners observe how wind creates ocean currents.

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

In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of 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 will explore how density is affected by temperature and how that can create currents.

In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

In this activity, learners explore a bucket of sand and beach objects.

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.
