Free Year 8 Science practice — calculate energy use, cost, power and work, then compare resource evidence. No account needed.
Calculate power, joules, kilowatt-hours, stated energy costs and mechanical work, then compare bounded resource evidence. Correct answers can trigger celebrations. Feedback and retry options depend on the game.
Learning objective: Choose consistent units and equations for energy calculations and keep cost and resource conclusions within the stated scenario.
Curriculum anchor: England KS3 Science: energy changes and transfers; work done; power; fuel use and costs; energy resources.
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 the learner to write the equation and units first, then identify any tariff or operating assumption. 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.
