EDEXCEL IGCSE CHEMISTRY Matter, Diffusion and Separation Complete Resource Bundle

49 files across 7 fully resourced lessons covering the complete Edexcel IGCSE Chemistry states of matter, solutions, and separation techniques topic (spec points 1.1–1.13C). Every lesson includes a PowerPoint with detailed speaker notes, a tiered worksheet (Must/Should/Could), homework, a scaffolded support task, key terminology sheet, knowledge organiser, and full mark scheme. Five lessons include practical guidance covering cooling curves, dilution of coloured solutions, investigating solubility of a solid in water, separation by filtration and crystallisation, and paper chromatography. Single Award and Double Award content included, with Chemistry-only material clearly labelled (1.5C, 1.6C, 1.7C, 1.13C). Designed for mixed-ability classrooms — differentiation is built into the structure, not bolted on. A cover teacher could deliver any lesson from the speaker notes alone.
Lessons included:

States of Matter — particle model, arrangement, movement and energy; interconversions between solid, liquid and gas; changes of state (1.1, 1.2)
Diffusion and Solutions — diffusion in coloured solutions and gases; key terms: solvent, solute, solution, saturated solution, solubility (1.3, 1.4, 1.5C)
Solubility Curves — solubility in g per 100 g of solvent; plotting and interpreting solubility curves; investigating solubility at a specific temperature (1.5C, 1.6C, 1.7C)
Elements, Compounds and Mixtures — classifying substances; fixed melting and boiling points of pure substances vs ranges for mixtures; particle diagrams (1.8, 1.9)
Separating Mixtures — filtration and crystallisation; separating rock salt; practical guidance included (1.8, 1.10)
Separating Techniques – Distillation — simple and fractional distillation; demo of simple distillation set-up (1.10)
Chromatography — paper chromatography technique; interpreting chromatograms; calculating Rf values; identifying components of a mixture (1.10, 1.11, 1.12, 1.13C)
