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

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

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

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this activity (p.26 of PDF), learners discover why mushrooms have spots. Learners use a balloon, toilet paper, and water to simulate what happens as mushrooms grow.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

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

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

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.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.
