Fireworks!

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced. The color is determined by the combustion of a metallic compound, and different solutions produce different colors. Flame tests can also be used to determine the composition of materials. This activity is currently used in the Industrial Chemistry Unit in OMSI's Chemistry Lab but can done in any chemistry lab. Cost estimate does not include lab equipment. For safety reasons, this activity should be conducted as a demonstration for younger audiences.
