In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

Coins are everyday objects which tell a lot about the people who use them.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners explore mammal locomotion by constructing flipbooks.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.
