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.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

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 sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

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 activity, learners discover how solar energy can be used to heat water.

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

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity, learners explore the different heating properties of soil and water.

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

In this data collection activity about crabs, learners use data from the Virginia Institute of Marine Science (VIMS) trawl survey to determine the areas of the Chesapeake Bay that are being used by bl

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.
