Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.

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.

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.

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.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

Learners compare the properties of two balls that appear identical. One ball bounces, while the other ball "thuds." The “bounce” ball is made of the polymer polybutadiene (-C4H4-).

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

Learners place their hands on different metals and use an ammeter to monitor the flow of electricity from one metal to another.

Learners observe working lava lamps to understand how they work (included in PDF link).

In this activity (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre
