In this outdoor activity/field trip, learners investigate the special shapes, holding structures and holding behaviors that real organisms use in streams, rivers, creeks or coast intertidal zones to a

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

In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.

In this outdoor activity/field trip, learners explore an aquatic site such as a pond, lake, stream, river or seashore to find and investigate plants and animals that live in water.

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

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 design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

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).

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

In this activity, learners will explore how density is affected by temperature and how that can create currents.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

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.
