Free Year 8 Science practice — trace boiling, condensation and fraction separation. No account needed.
Explain fractional-distillation apparatus, boiling-point reasoning and the limits of collected fractions. 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: Trace repeated vaporisation and condensation and use boiling ranges without overstating purity.
Curriculum anchor: England KS3 Science: mixtures; separating techniques; simple and fractional distillation; properties of materials.
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 component is more volatile, where it condenses and whether the collected fraction is truly one substance. 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.
