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

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.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

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.

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

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

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.
