Free Year 7 Science practice — explore microphones, ultrasound, seismic waves, radio and microwaves. No account needed.
Trace information through microphones and speakers and reason about selected uses of ultrasound, seismic waves, radio waves and microwaves. 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: Connect wave transfers to selected technologies and choose cautious explanations of bounded ultrasound, seismic and communication applications.
Curriculum anchor: England KS3 Science: energy transfer by waves; sound detected by microphones and loudspeakers; and selected uses of ultrasound and electromagnetic waves.
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 type of wave carries the energy and what evidence a receiver detects; medical images require trained interpretation. 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.
