Introduce your learners to Hess’s Law as a means of measuring enthalpy changes using this lesson plan with simple experiments

In this session, learners carry out two simple practical activities to observe what happens when water is added to anhydrous copper(II) sulfate, and when hydrated copper(II) sulfate is dissolved in water.

The activity is designed to help students recognise that some enthalpy changes cannot be measured directly, and to introduce them to Hess’s Law and its application.

Assessment for learning (formative assessment) provides a structured approach to revealing what your learners understand of the topic. 

Full teacher notes, student worksheet, classroom presentation and technician notes provide everything you need for the lesson. 

Suitable for learners on A-level and equivalent 16–18 courses.
