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

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 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.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

In this chemistry demonstration, acid rain is simulated in a petri dish.

This is a series of demonstrations about different electrical and magnetic phenomena.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this activity, learners perform a simulated blood test procedure.

In this activity, learners discover that atoms and ions of different metals will change places.

In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.

In this activity (on pages 25-31 of PDF), learners soak sponges with different amounts of plaster of paris to simulate different levels of calcification in bone formation.

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.
