National Curriculum
62 lessons across 11 units
This is the complete topic map for KS3 Chemistry— every part of the national curriculum for Key Stage 3, organised the way it's taught: 62 lessons across 11 units, from Acids and alkalis to Separation. Each topic below opens a focused revision lesson, so “what should we look at tonight?” always has an answer.
The course is organised into 11 units: Acids and alkalis (7 lessons), Atoms and elements (7 lessons), Chemical reactions (6 lessons), Climate chemistry (4 lessons), Earth and atmosphere (9 lessons), Energetics (2 lessons), Materials (5 lessons), Mixtures and solutions (5 lessons), Particle model (7 lessons), Periodic table (4 lessons) and Separation (6 lessons). Together that's 62 lessons — the whole course, with nothing skipped and nothing added.
Little and often beats cramming. One topic a night, done properly — read it, try the questions, check yourself — moves a grade more than a weekend binge the week before the exam. The list above is deliberately complete so you can tick through it a topic at a time.
Start from what's coming up, not from the beginning. If a class test or mock is near, open the unit it covers and work through those topics first. Between assessments, work through units in order — later topics usually build on earlier ones.
For parents:you don't need to know the subject to help. Ask which topic tonight's lesson was, open it here, and let them teach it back to you — explaining something out loud is one of the most effective revision techniques there is. At KS3 the habit matters more than the coverage: little routines now are what GCSE revision gets built on.

KS3 Chemistry follows the national curriculum, so it isn't tied to a specific exam board — boards like AQA and Edexcel set GCSE specifications (Key Stage 4), not KS3. This page lists the national-curriculum topics for KS3 Chemistry.
