Part of the AQA GCSE Combined Science curriculum.
AQA GCSE Combined Science 5.4 Chemical Changes is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the AQA specification (AQA GCSE Combined Science: Trilogy (8464) – 5.4 Chemical changes). It covers metals, oxygen and the reactivity series, extracting metals and redox, reactions of acids, making soluble salts, pH, neutralisation and strong and weak acids, electrolysis of molten compounds and electrolysis of aqueous solutions, then brings it all together with mixed retrieval and exam practice.
There are 23 short steps of about 15 minutes (roughly 6 hours of learning), each made of bite-size explanations with key words, tables and examples, and every bite-size is followed by an activity you check straight away. Key terms include Metal oxide, Oxidation, Ore, Reduction with carbon, Salt, Base, Soluble salt, Excess, pH scale, Hydrogen ion, Electrolysis and Electrolyte.
