GCSE Chemistry Energy Changes: AQA-style workbook, practice papers and lessons

A complete, illustrated pack for the GCSE Chemistry energy changes topic: a 91-page workbook with full worked answers, 6 editable PowerPoint lessons and two practice papers. It covers exothermic and endothermic reactions and their everyday uses, the temperature-change required practical, reaction profiles and activation energy, bond energies and the overall energy change (Higher), and, for GCSE Chemistry, chemical cells, batteries and hydrogen fuel cells with their half equations (Higher).

WHAT’S INSIDE (updated October 2026)

• Workbook 91 pages, answer edition 85 pages (editable Word)
• Practice papers 9 pages, mark schemes 9 pages (editable Word)
• Knowledge organiser and flashcards 13 pages
• 6 lesson decks (editable PowerPoint), 201 slides in total. Every lesson ends with exam questions and worked answers that build on click
• Teacher guide (Word)
• Learner and teacher toolkit 19 pages
• Lesson teacher notes (PDF) 12 pages
• Thank-you and next steps page
• Total: 240 PDF pages and 201 slides

WHAT YOU GET

• 227 questions graded Foundation, Developing and Exam standard (84, 81, 62), with mark tags: classifying reactions from temperature data, reading and drawing reaction profiles, counting bonds from displayed formulae, bond-energy calculations with the correct sign, finding an unknown bond energy, cell voltage predictions, and 36 retrieval questions
• 30 step-by-step worked examples, each answer checked a second way. Every equation is balanced in code and every bond count is checked against the drawn molecule
• 32 diagrams drawn for this pack, including the polystyrene-cup set-up, exothermic and endothermic profiles with and without a catalyst, displayed-formula bond diagrams, a simple cell and a hydrogen fuel cell
• The required practical in full: method, variables, results table with an anomaly, two lines of best fit, conclusion and evaluation
• Six-mark questions with three-level mark schemes and indicative content, plus a model Level 3 answer built step by step
• Mistake clinic with fourteen misconceptions and twelve spot-the-error tasks, three retrieval quizzes, a 19-point checklist and a glossary of 26 terms
• Two 40-mark practice papers with mark schemes (PDF and editable Word), a knowledge organiser with 36 flashcards and a teacher guide

WHO IT IS FOR
Chemistry and Combined Science teachers, students and tutors. Higher tier items are labelled, and cells and fuel cells are in sections labelled Chemistry only.

ABOUT THE SPECIFICATION
Written with the AQA GCSE energy changes content in mind. Questions use an AQA-style format; tier and course labels, mark guidance and timings are Study Hack’s own, not an exam board mark scheme. Please check your own specification. Experimental readings and cell voltages are invented for practice, and bond energies are typical values: always use the values a question gives.

All questions, diagrams and model answers are original Study Hack material. Independent resource, not endorsed by any exam board.
