Free Year 8 Science practice — calculate moments, balance forces and reason about levers. No account needed.
Calculate moments, balance clockwise and anticlockwise effects, reason about stability and interpret lever 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: Choose the correct pivot, perpendicular distance and units, then distinguish moment balance from force balance and practical stability.
Curriculum anchor: England KS3 Science: forces and moments; levers; balanced forces; centre of mass and stability.
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 the learner to mark the pivot and line of action before calculating, then name any real-world friction or load limitation. 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.
