Fireworks capture our attention with their beautiful colors and controlled explosions, both of which link directly to fundamental concepts taught in basic chemistry classes. The media resources featured in this lesson provide a visually rich way to tie together spectral chemistry, combustion, and the nature of fire. Students watch a video segment and read text about the color of fireworks (particularly useful when following a chemistry lab in which powders of elements are placed over a flame to observe their spectral emission). They also watch a video segment and do an interactive activity on the mechanics of a firework, which leads to optional interactive activities for those wanting a slightly more advanced chemistry lesson involving chemical reactions. They wrap up by viewing video segments of many different types of fireworks and explaining the principles of chemistry and pyrotechnics that create all their glory.

Chemical Reactions

by Jared Schwartz

Students will explore the different types of chemical reactions and how each of them functions. The following video will give brief overview of the different reactions and by the end of the lesson, students should be able to practice the different reactions on their own to be prepared for the next lesson.

The guided inquiry activity enables students to identify the five basic types of reactions - synthesis or composition, decomposition, combustion, single replacement and double replacement. Students will also begin to predict the products for each of these types of reactions.
