As the G10 science class in the MYP program gets ready for their upcoming e-assessment, they have been exploring exothermic and endothermic reactions in the lab. The highlight of their experiments was the oxidation of glycerin by potassium permanganate, an extremely exothermic reaction that had to be conducted outside, due to the heat and fire produced from the resulting reaction. This was an obvious example of exothermic chemistry, and with all of the precautions in place, the students were able to see the reaction take place. These experiments allowed the students first–hand experience with the types of chemical reactions, which enhanced their learning of chemical energetics and reaction types, specifically in preparation for their e–assessment.
