The Nervous System and Reflexes — Interactive Lesson (Ages 14–16)

Touch a hot pot and your hand jerks away before you even think. How does the body react so fast? This 22-slide interactive lesson on reflex arc takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching The Nervous System and Reflexes in GCSE Biology

Pupils trace the pathway from stimulus to receptor, coordinator, effector and response, name the parts of the central nervous system and compare sensory, relay and motor neurones. They put the reflex arc in order, sort reflex from voluntary actions, explain how chemicals carry impulses across synapses and interpret results from the ruler drop reaction time practical.

What Pupils Will Learn

• Describe the pathway from stimulus to response.
• Name the parts of the central nervous system.
• Describe sensory, relay and motor neurones.
• Explain how a reflex arc works and why reflexes are important.
• Describe how impulses cross a synapse.
