Teacher's field guide

What Students Need to Do: Students identify the brain and spinal cord as the central nervous system. They identify nerves outside those parts as the peripheral nervous system and explain how messages travel between the two.
What Mastery Looks Like: A student can label both divisions on a body diagram and describe each one's job. They can explain how nerves carry a signal from a hot pan to the spinal cord and a response back to the hand.
Common Misconceptions: Students may put the spinal cord in the peripheral system or think the brain alone makes up the central system. They may also think every response waits for a conscious decision from the brain.
How to Assess It: Give students a blank body outline. Ask them to label the brain, spinal cord, and arm nerves, then write how those parts help them pull a hand from a hot pan.

Lesson moves

Give pairs a body outline and yarn to trace the brain, spinal cord, and nerves, then label the two divisions.
Ask students to write two sentences answering: Why can your hand pull away from a hot pan before you decide to move it?
Have pairs sort brain, spinal cord, and nerve cards into central and peripheral groups, then explain one choice.
Ask students to trace how they feel a phone vibrate and move a hand to silence it.
