Neurons & Brain Structure
Explain how neurons transmit signals as electrochemical impulses across synapses, describe how the brain is organised (lobes and functions, limbic system for emotion), and explain neuroplasticity — why learning and practice physically change brain structure — connecting to optical illusions as evidence that the brain constructs reality rather than passively recording it
Typical age: 11–13 years
“If your child was asked why practising a skill like piano or football makes you better over time, could they explain what's actually happening physically in the brain — and describe what it means to say the brain 'rewires itself'?”
