AQA GCSE Combined Science Chemistry C5 Energy Changes: 4 lessons ready to teach, with a topic test
This is the Combined Science Trilogy version of C5 Energy Changes, matched to the AQA 8464 specification. You get 3 teaching lessons and the 1 required practical as full lessons, all planned and ready to teach in editable PowerPoint.
What your classes work through
- Exothermic and endothermic reactions. Pupils average three temperature rises of 7, 8 and 9 °C from an acid and alkali mixture and use the result to classify the reaction.
- Reaction profiles and activation energy. Pupils sketch the energy story of a reaction that gives out heat but needs a flame to start, placing products below reactants.
- Bond Energies and Energy Change. Pupils measure the hump and the overall drop or rise on a graph for reaction Y in kJ/mol, then decide if it gives out or takes in heat.
The 1 required practical
- RP10 Temperature Changes. Pupils multiply mass, 4.2 and the 6 °C rise to find how much energy a neutralisation transferred to the solution.
Who it is for
Use it to teach C5 Energy Changes for AQA GCSE Combined Science Trilogy, with lessons on exothermic and endothermic reactions, reaction profiles, activation energy and bond energies. It also supports Combined Science Chemistry revision in KS4 and includes the temperature changes required practical.
How each lesson runs
Each C5 Energy Changes lesson starts with a Do Now that recalls earlier learning, with the answers on the next slide. It then moves through I Do, We Do and You Do, with a model answer after each task. It finishes with the AQA-style question listed above, its mark scheme and an exit ticket. A specification slide names the AQA points the lesson covers, so you can check it against your scheme of work.
Topic test
The C5 Energy Changes topic test covers the whole unit with AQA-style questions and comes with its mark scheme, both in Word and PDF.
