More Than Meets the Eye: Nonvisual Observations in Chemistry

In this Activity, a blindfolded student, with another student as an assistant, observes the reaction between baking soda and cream of tartar in solution in a plastic bag. The Activity could be used at the start of a chemistry course to emphasize the importance of using all appropriate senses to make observations. The Activity could also be used to demonstrate examples of acid-base reactions, reactions of carbonates, or endothermic reactions. It also serves to sensitize both students and instructors to the topic of modifications for those with special needs.
