Free Year 8 Science practice — predict acid-metal products and compare oxide pH patterns. No account needed.
Predict selected acid-metal products and distinguish broad acidic, basic and amphoteric oxide behaviour. The default practice mode is untimed, so the learner can think before choosing. Correct answers build a gentle celebration; mistakes receive corrective feedback and return later rather than causing a penalty spiral.
Learning objective: Connect products, reaction evidence and pH patterns while respecting controls, exceptions and practical limits.
Curriculum anchor: England KS3 Science: chemical reactions; acids with metals; pH; properties of metal and non-metal oxides.
This game is designed as short independent practice after an idea has been introduced. It does not replace direct teaching, mathematical or scientific discussion, or an adult checking whether the learner can explain the idea away from the screen.
Ask which product rule applies, what was actually observed and where a broad oxide rule has exceptions. Stop while attention is still good. A short accurate return tomorrow is more useful than extending a tired session today.
Does it need an account? No. The game runs in the browser and asks for no name, email address, school or location.
Is it timed? Practice is untimed. Where a sprint exists it is optional. Times Tables Sprint also includes MTC-style independent practice, not an expected-standard judgement.
Can it be used on a phone? Yes. Buttons support touch and keyboard use; sorting always has a tap alternative to dragging.
