Free Year 8 Science practice — use periodic-table structure, group patterns and Mendeleev’s evidence. No account needed.
Use modern periodic-table layout, compare selected group trends and evaluate Mendeleev’s evidence and predictions. Correct answers can trigger celebrations. Feedback and retry options depend on the game.
Learning objective: Read table structure, connect outer-electron patterns to selected group behaviour and explain how predictions supported classification.
Curriculum anchor: England KS3 Science: periodic table; groups and periods; metals and non-metals; varying physical and chemical properties.
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 distinguish an observed pattern from a universal rule and explain how a prediction could test a model. 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.
