What it practises
- Deep reflection & analysis: Slowing down: weighing evidence, spotting weak arguments and explaining why something worked.
- Concepts & theory: The science and maths behind the game: reflection, orbits, waves, circuits, ciphers.
- Sustained focus: Longer sessions of steady effort, with check-ins when you start to slow down.
Fast games can crowd out slow thinking, so this skill uses untimed games and written reflection.
Quick lesson: Fair tests
In a fair test you change one thing (the independent variable), measure one thing (the dependent variable) and keep everything else the same. Control groups, random groups and repeats make results more trustworthy.
Check question
You test whether music helps plants grow. What must stay the same?
- The kind of music
- Light, water and soil
- Whether there is music
- Nothing needs to stay
Answer: Light, water and soil. Only the music should change; light, water and soil stay the same.
