Free Year 4 science practice — heating, cooling, named state changes, reversibility and temperature evidence. No account needed.
Name melting, freezing, evaporation and condensation; compare heating/cooling evidence and distinguish reversible state changes. Correct answers can trigger celebrations. Feedback and retry options depend on the game.
Learning objective: Choose names and explanations for supplied state changes and interpret specified temperature observations. Independent measurement, investigation and independently produced explanations are not assessed.
Curriculum anchor: England Year 4 science: observe state changes when materials are heated or cooled and research change temperatures.
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.
Keep heating supervised and use ice or water examples; avoid burning or baking as state-change demonstrations. 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.
