Temperature changes in exothermic and endothermic reactions

Energy is at the heart of chemical energetics, so supporting students in linking observation of temperature change with the energy transfers taking place is important.

Use this experiment and accompanying student worksheet to boost your students’ understanding of chemical energetics and energy transfer in exo- and endothermic reactions, encouraging them to think about the ‘chemical story’ and ‘energy story’ of the reactions.

Use this resource alongside the Education in Chemistry article ‘How to teach chemical energetics’.
