In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

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).

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

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.

Educator Amy O'Donnell from the American Museum of Natural History guides learners to create a diorama of a coral reef.

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 construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.
