Exothermic and Endothermic as per AQA specication (Combined science/GCSE Chemistry). Full set of slides, spaced practice and opportunity for self/peer assessment. Slides and worksheet can be easily adapted to suit other lessons/revision activities. Measuring temperature change - AQA Combined science and GCSE Chemistry Chemical Changes. Series of practical activities and associated questions that can be adapted for a range of abilities. Simulation practical Foundation style practical Higher level practical and use of graph and LOBF to determine temperature change for endothermic and exothermic Reaction Profiles - slides and activities that gets students to think about the change of energy in a reaction, practise drawing reaction profiles, calculating the difference in energy between reactants and products. The use of cataysts and their effect on activation energy is also elicited here. Associated worksheets are included. This resource is geared towards AQA combined science and GCSE chemistry but can be easily adapted. Bond energy - eliciting prior knowledge of latent heat and introducing the concept of energies associated with bond breaking and bond forming. This is a complete lesson as per AQA combined science and GCSE Chemsitry specifications on Energy Changes. The worked examples and questions used here can be easily adapted. This resource also includes a mini teacher assessment.
