Looking for ways to make stoichiometry engaging and memorable for your students? In this activity students gain a first-hand understanding of the importance of balanced ratios of reactants as they investigate the correct ratio of citric acid and baking soda for making fizzy drinks. During the process students discover the key to a proper fizzy drink lies in choosing moles over grams. This presentation will provide an overview of the activity including important notes for teacher facilitation and a summary of reported student outcomes. Participants will also learn how to access complete student and teacher guides for this activity and more.
