Free Year 9 Science practice — stomata, pollination and seed dispersal. No account needed.
Connect stomatal structure to gas exchange and evaluate flowering-plant and wind-dispersal 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: Use plant structures, functions and controlled model evidence without turning a bounded result into a universal claim.
Curriculum anchor: England KS3 Science: gas exchange in plants, flowering-plant reproduction and analysis of seed-dispersal investigations.
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 structure performs each function, then which controls and repeats make a dispersal comparison credible. 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.
