Free Year 4 science practice — vibrations, sound travel, insulation, speed through materials and bottle pitch. No account needed.
Trace sound from vibration through solids, liquids and gases, compare insulation tests, reason about broad speed patterns and predict blown-bottle pitch. Correct answers can trigger celebrations. Feedback and retry options depend on the game.
Learning objective: Choose explanations of sound travel and interpretations or predictions for specified insulation, speed and blown-bottle examples.
Curriculum anchor: England Year 4 science: identify how sounds are made, associate some with vibration, recognise vibrations travel through a medium to the ear, find pitch patterns and decreasing volume 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.
Use moderate sound levels and supervised investigations; specify whether bottles are blown or struck because the pitch trend can differ. 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.
