Part of the Edexcel GCSE Combined Science curriculum.
Edexcel GCSE Combined Science Topic 2 States of Matter and Mixtures is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the Edexcel specification (Pearson Edexcel GCSE (9–1) Combined Science (1SC0) – Topic 2 States of matter and mixtures). It covers the three states of matter, changes of state, pure substances and mixtures, filtration and crystallisation, simple and fractional distillation, paper chromatography and inks and making water potable, 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 Particle model, Solid, Melting, Condensing, Pure substance, Mixture, Filtration, Residue, Simple distillation, Condenser, Paper chromatography and Stationary phase.
