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.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

"Molecules in Motion" explores how materials behave and change in a vacuum.

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

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-).

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

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

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

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.

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
