Mentos and the Scientific Method: A Sweet Combination
Abstract
We describe an inquiry-driven exercise conducted in both the lecture and laboratory components of a college introductory chemistry course for nonmajors. The exercise involved using the scientific method to investigate the cause of the fountain effect observed when Mentos candies are added to Diet Coke. Collaborative group discussion was used to create hypotheses and design the corresponding experiments, and the results from the inquiry-driven laboratory exercises are summarized, along with the results from a postlab student reflection survey. This exercise effectively integrated activities in the lecture and laboratory, fostered student interest in chemistry, and immersed the students in the process of scientific inquiry.
