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.

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.
