This is a simple and fun activity for learners to explore water and colors.

In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

Learners follow a three-step process to start their own rock collection.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners listen to a story and tell a story of their own as they learn about the importance of elders in Native American cultures.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

In this outdoor activity, learners discover the wonders of the habitat surrounding them.
