Free Year 9 Science practice — energy calculations, Sankey diagrams and upthrust. No account needed.
Calculate kinetic and gravitational energy, interpret descriptions of Sankey diagrams and explain upthrust from fluid pressure. Correct answers can trigger celebrations. Feedback and retry options depend on the game.
Learning objective: Apply equations with units, track conserved energy and use displaced-fluid reasoning without claiming practical competence.
Curriculum anchor: England KS3 Science: energy stores and transfers, work and machines, Sankey diagrams, pressure in liquids and upthrust.
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 for the equation, units and force directions before accepting a numerical or floating explanation. 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.
