To revisit our work in Science on changing states, we decided to bake rice krispie reindeers. The children worked in small teams to read the recipe, measure the ingredients accurately, and discuss what was happening to the marshmallows and chocolate when they were heated and cooled. It was great to hear all the vocabulary from science being discussed: melting, cooling, heat, change of state, reversible change, irreversible change, etc. The finished products certainly looked amazing and tasted even better.
