Free Year 7 Science practice — interpret atoms, molecules, elements, compounds, symbols and formulae. No account needed.
Distinguish atoms, molecules, elements and compounds using descriptions of simple particle diagrams, symbols and formulae. Correct answers can trigger celebrations. Feedback and retry options depend on the game.
Learning objective: Interpret descriptions of selected particle representations, recognise common symbols and read the composition shown by simple formulae.
Curriculum anchor: England KS3 Science: a simple atomic model; atoms and molecules; elements and compounds; chemical symbols and formulae.
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 what each symbol names and how subscripts change the number of atoms represented, without guessing arbitrary ionic formulae. 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.
