Free Year 6 Science practice — trace circulation and explain how blood transports substances. No account needed.
Trace a simplified double circulation and explain the roles of the heart, vessels, blood and transport between organs and tissues. 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 a simplified double circulation and explain the roles of the heart, vessels, blood and transport between organs and tissues.

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.
Use a labelled model or diagram alongside the game and keep personal health questions for an appropriate professional. 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.
