In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this activity, learners model estuaries, artificially enriching both fresh and salt water samples with different amounts of nutrients and observing the growth of algae over several weeks.

In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

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 chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

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 activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.

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

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this activity, learners construct a device that allows them to look over ledges or around corners.
