The Nervous System
Understand that the nervous system has two parts — the central nervous system (brain and spinal cord) and nerves that branch throughout the body — and that nerve signals travel at high speed to coordinate senses, thought, and movement
Lesson
Set out your lesson
“The Nervous System means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A simple body outline printout or drawing
- Pencil and labels
Extra for the adult
Worked example. The brain sends signals so muscles know when to move.
Optional challenge. For The Nervous System, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples The Nervous System, not mastery.

Check understanding
- Name the two parts of the nervous system: central (brain + spinal cord) and peripheral (nerves throughout the body)
- Describe the reflex arc: stimulus → sensory nerve → spinal cord/brain → motor nerve → muscle response
- State that nerve signals travel extremely fast, which is why reflexes happen almost instantly
“Can your child explain how a message travels from their finger to their brain when they touch something hot, and then back to their hand to pull it away?”
