Free Year 7 Science practice — reason about light waves, materials, colour and dispersion. No account needed.
Reason about selected light-wave properties, reflection, transmission, absorption, colour and dispersion. 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: Classify selected light interactions, explain perceived colour and trace how white light forms a spectrum.
Curriculum anchor: England KS3 Science: light waves; transmission through materials; absorption and reflection; colours and the different frequencies of white light.
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 whether light is reflected, transmitted or absorbed and keep screen-light mixing distinct from pigment mixing. 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.
