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 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 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.

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

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

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

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

In this activity, learners will construct an air cannon as a model for the human ear.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.
