In the world around us, reactions are happening all the time, especially in Palo Alto High School’s Chemistry Honors classes. Recently, students completed labs in which they had to test how different factors affected the reaction rate of an alka seltzer tablet. It was a full hands on activity, with students taking lead on the variables that they tested. The only instructions were to keep the mass of the reactants constant. Factors ranging from surface area to temperature were tested by multiple groups of 3-4 students, all of them testing different variables at different levels.
