AQA 5.5.1.1 9-1 Specification. Endothermic and Exothermic reaction in terms of energy transfer

These lessons discuss endothermic and exothermic reactions.
The first lesson covers AQA trilogy 5.5.1.1 and discusses definitions relating to change in temperature, breaking and making bonds and some examples. There is a practical (based on RSC classic chemical experiments) that asks students to deduce if the reactions are endo or exo to reinforce this concept. I have included a worksheet for this.
The second lesson is the AQA required practical. I have included information taken directly from the AQA guidelines from their required practical. But have written a powerpoint to accompany it that includes an animation to assist with the graph task.
