Free Year 4 science practice — vibrating sources, pitch patterns, volume, amplitude and distance. No account needed.
Identify vibrating sources and reason from controlled string, bar, bottle, strike-strength and distance comparisons. Correct answers can trigger celebrations. Feedback and retry options depend on the game.
Learning objective: Distinguish pitch from volume and connect each with controlled source features, vibration strength and distance.
Curriculum anchor: England Year 4 science: find patterns between pitch and object features, volume and vibration strength, and fainter sound with distance.
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.
Change one feature at a time at moderate sound levels; state whether bottles are blown or struck. Take a break when you need one.
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? Timing varies by activity. Check the available modes and instructions before starting.
Can it be used on a phone? Controls vary by game. Use the on-screen buttons or read the instructions for keyboard and drag actions.
