In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.

This is an activity about a very important ingredient in most baked goods - gluten! Why is gluten so important? Without it, there would be nothing to hold the gas that makes bread rise.

In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.

Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

In this activity learners will create paint out of natural materials. Explore your natural world (or your fridge) and find berries, leaves, or flowers to find a great base for your paint.

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

In this activity, kids make and play with Ooze before testing the material in an egg drop!

This lab activity has learners create a pendulum with a one-second period.

Learners are given mysterious white powders and have to determine their identity with chemical tests.

Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

In this activity, learners of all ages will experiment with paint and printmaking.

In this activity, learners will make their own slushies and learn some of the science behind how the process works.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners will explore pendulum motion through scientific trials by using household items with different length strings.

In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.
