Year 8 Science Chemistry Revision Practice

Criterion-by-criterion revision practice for Year 8 Chemistry, with 192 questions across 48 skill criteria and 6 topics: structure of the atom, using the periodic table, elements, compounds and mixtures, physical change, chemical change, and rates, corrosion and combustion. Pick a criterion from the sidebar to get a short teaching intro and then work through its questions: 144 short-answer items with mark allocations and 48 multiple choice, 428 marks in total. Every question reveals a worked solution split into separate steps showing where each mark is earned, and self-marking with Got it / Partly / Missed fills a per-criterion progress bar so gaps are visible at a glance, with progress saved in the browser between sessions and a history panel of past attempts. 56 questions regenerate as similar questions with fresh numbers, substances and scenarios for extra practice. A pop-up calculator, a periodic table reference, and sketch and scratchpad canvases are available while working, and all 46 diagrams (particle arrangements, shell diagrams, element boxes, particle-diagram classification) are embedded in the page itself.
