This case study provides a summary about the discovery of saccharin. In this lesson, students learn about the accidental discovery and the chemistry behind this innovation. They learn about redox reactions and how to identify the oxidizing and reducing elements. Students use this information to research a substance that was banned based upon incorrect evidence and present the scientific evidence to the public through a public campaign. The lesson is best suited for high school students with some knowledge of redox reactions. It may be taught during a unit on single replacement chemical reactions. It also fits well into a lesson on redox reactions or balancing chemical equations. As a fun fact, today, saccharin is the third most popular artificial sweetener in the United States. A materials list, teacher notes, teacher background information, safety notes, standards, assessment, resources, and references are provided. This book selection also includes the Table of Contents, About the Authors, Acknowledgments, Introduction, Appendix, Image Credits, and Index.
