See the Light

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light. Learners discover that some chemical reactions release energy in the form of light, and that this process is called chemiluminescence. Activity guide includes examples of chemiluminescence in nature and commercial products. This activity is currently used in the Chemical Reactions Unit in OMSI's Chemistry Lab. Cost estimates are per 100 students.
