In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.

In two separate bags, learners mix water with Epsom salts and detergent.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this chemistry activity (page 1 of the PDF), learners will observe a physical change.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.

In this activity, learners will explore saturated solutions and discover how crystals form.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

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

In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.

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 experiment with how dish soap and fat interact by making a colorful swirl.

How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

Visitors observe a tray holding a crystal-covered brick. The crystals were created by evaporation of a solution containing liquid bluing, ammonia, and salt.
