The Nervous System means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A simple body outline printout or drawing; Pencil and labels. 1. Say the goal of The Nervous System in plain words once. 2. Adult points to one organ or system and names its job in plain words. 3. Child labels three parts and says the job of each. 4. Fresh check: one fresh organ/system job. Record and stop. Done: three correct labels with a job sentence each. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

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?”
