Free Year 8 Science practice — connect viscosity, convection and insulation evidence. No account needed.
Relate viscosity and convection to particle behaviour and evaluate controlled insulation evidence. 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 flow and energy transfer to particle motion and density while keeping practical conclusions bounded.
Curriculum anchor: England KS3 Science: particle model; motion and spacing with temperature; thermal energy transfer; convection and insulation.
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 what moves, what changes density or flow resistance and which variables make the comparison fair. 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.
