A no-prep, 6-lesson science unit on GCSE Chemistry (AQA 4.4): the reactivity series; extraction of metals and reduction; reactions of acids with metals, bases and carbonates; salts and neutralisation; the pH scale; (Higher) strong vs weak acids; electrolysis of molten and aqueous compounds and half-equations, written for Key Stage 4 / GCSE (ages 14-16). Phenomenon-first and three-dimensional: every lesson opens with something to wonder about and builds toward the unit’s big question. Open and teach — full teacher plans, projectable slides, three differentiated pupil worksheets per lesson, a complete printable lab pack, a knowledge organiser, and a baseline + end-of-unit assessment.

Big question: Why are some metals so reactive, and how do we use electricity to split compounds?

What’s included

• 6 × Teacher lesson plans (Word) on the 5E spine (Engage · Explore · Explain · Elaborate · Evaluate)
• 6 × Pupil worksheets in 3 differentiated tiers (Support / Core / Stretch — mapped to Foundation Higher)
• 6 × Projectable slide decks (PowerPoint, 16:9 widescreen)
• 1 × Full required-practical lab pack (Word) — AQA RP: preparing a pure, dry sample of a soluble salt — method, fair-test variables, household and lab equipment lists, a real risk assessment, a blank results table, and analysis + conclusion scaffolds
• 1 × Knowledge organiser (Word, A4 landscape)
• 1 × Baseline + end-of-unit assessment with a teacher answer key — plus 6 original exam-style questions with full mark schemes and command words (describe / explain / evaluate / calculate)
• Hand-coded diagrams with clear labels for the unit’s key ideas — never AI-generated
• Original illustrations for every phenomenon hook
