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

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 observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.

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.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

Learners pour equal amounts of coffee, mineral oil, corn syrup, and alcohol into a beaker. The liquids resolve into stacked layers, and learners can infer which liquids are the most and least dense.

In this fun and delicious chemistry activity (page 1 of the PDF), learners will explore the difference between physical and chemical change by making homemade ice cream.

Visitors observe a graduated cylinder with a golf ball floating about halfway in liquid. The bottom half of the cylinder contains a concentrated solution of salt.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners investigate vitamin C.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.
