Materials Change Lab

Free Year 5 Science practice — explore solutions, separation and reversible or new-material changes. No account needed.

About Materials Change Lab

Explore dissolving, rate evidence, mixture separation and reversible or new-material 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.

Curriculum purpose

Learning objective: Choose material-change explanations and separation methods from stated evidence and properties.

Curriculum anchor: England Year 5 Science: solutions, recovery, separating mixtures and reversible or not-usually-reversible changes.

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.

For parents and carers

Keep practical work supervised and ask whether the starting materials can actually be recovered. Stop while attention is still good. A short accurate return tomorrow is more useful than extending a tired session today.

Frequently asked questions

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.
