In this activity, learners explore the etymology of dinosaur names.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.

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 activity, learners explore the Great Plains.

In this activity, learners will turn an ordinary tray of sand into a desk-top garden for meditation.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this activity, learners explore dinosaur fossils and skeletons. First, learners listen to "Tyrannosaurus Rex" by Daniel Cohen to learn about T. rex dinosaurs specifically.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.

In this activity, learners will investigate the impacts of harmful phytoplankton using NOAA's Coastal Services Center Harmful Algal Bloom Forecasting (HABF) Project data.

In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

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

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

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible
