Heat in? Heat out? Which is it? Introduce students to the energy changes that take place during exothermic and endothermic chemical reactions. In this lab activity, students perform three separate reactions—including both neutralization and dissolving of salts. With each set of reactants, students measure the significant temperature changes that occur in each calorimeter, and then determine the amount of heat released or absorbed by the reaction. Students classify each reaction as exothermic or endothermic and write the chemical equation.
All necessary chemicals, calorimeter cups, Teacher Notes, and reproducible student handouts are provided in the kit.
Complete for 30 students working in pairs.
