In this activity, learners will use clear nail polish and the power of chemistry to create paper with a rainbow sheen.

Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

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 explore the different salinities of various sources of water by taste-testing.

In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

In this activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

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

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.
