In this activity, learners investigate vitamin C. Using a simple starch and iodine demonstration, learners discover that vitamin C is an antioxidant, and protects us by reacting with toxic compounds before they can harm us. This activity is currently used in the Everyday Chemistry Unit in OMSI's Chemistry Lab. Cost estimates are per 100 learners.
