Free Year 7 Science practice — classify purity, particle models, phase-point evidence and air composition. No account needed.
Use the scientific meaning of purity, interpret particle and phase-point evidence, and recall approximate dry-air composition. 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: Distinguish pure substances from mixtures using bounded definitions, models and measurements, then explain air as a variable mixture.
Curriculum anchor: England KS3 Science: pure and impure substances; particle models; melting and boiling points; mixtures; and composition of the atmosphere.
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.
Keep everyday label meanings separate from scientific purity and treat melting-point evidence as support rather than absolute proof. 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.
