Free Year 4 science practice — heating, cooling, named state changes, reversibility and temperature evidence. No account needed.
Name melting, freezing, evaporation and condensation; compare heating/cooling evidence and distinguish reversible state changes. 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 names and explanations for supplied state changes and interpret specified temperature observations. Independent measurement, investigation and independently produced explanations are not assessed.
Curriculum anchor: England Year 4 science: observe state changes when materials are heated or cooled and research change temperatures.
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.
Keep heating supervised and use ice or water examples; avoid burning or baking as state-change demonstrations. 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.
