Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

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

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

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.

This display shows slow chemical reactions in colorful crystal formations known as Liesegang Rings. These reactions are similar to those forming the rings in agates.
