The brain and nerves
How the brain gets messages from the senses and sends messages to the muscles, the main parts of the brain and the lobes, neurons and myelin, measuring reaction time with a falling ruler, the action potential and synapses, and the power the brain uses. Three ages, each with a text, an experiment, a game, a quiz, a printable worksheet and a teacher sheet.
Ages 6–7My busy brainWhere your brain is, what it does, and how messages travel in from your senses and out to your muscles. With a catch-the-ruler game.Ages 10–11The brain: parts, jobs and reaction timeThe cerebrum, cerebellum and brain stem, two hemispheres and four lobes, the nervous system and neurons. With a reaction-time fair test.Ages 15–16Neurons, action potentials and reaction timeNeurons and glia, grey and white matter, resting and action potentials, myelin and synapses, the brain's power use, and calculating reaction time with free fall. With a reaction-time investigation.
