Cover: The Chemistry of Candy and Sugar

Candy-making is a sweet endeavor that appeals to chemists and cooks alike. In the article Chemistry of Candy: A Sweet Approach to Teaching Nonscience Majors, Jennifer Logan Bayline, Halie M. Tucci, David W. Miller, Kaitlin D. Roderick, and Patricia A. Brletic describe a course that combines laboratory experiments and candy-making exercises to teach general chemistry principles and data collection. Making candy incorporates chemistry concepts into a course, such as solution concentration, colligative properties, and phase transformations, while flavoring and color reflect synthesis or extraction.
