What This Standard Means
What Students Need to Do
- Students identify the main parts of a neuron and trace how a message passes between neurons. They explain how that signaling can affect a response, such as turning toward a sound, or a mental process, such as paying attention.
What Mastery Looks Like
- Given a sketch of two neurons, students label the dendrites, cell body, axon, myelin, terminals, and synapse. They show an electrical signal traveling down the axon and neurotransmitters crossing the synapse to receptors on the next neuron.
Common Misconceptions
- Students may think neurotransmitters travel down the axon instead of crossing the synapse. They may also think myelin creates the signal or that one neurotransmitter always causes one specific feeling.
How to Assess It
- Give students a blank sketch of two neurons. Ask them to label the parts, draw the electrical and chemical steps, and explain how those signals could help them notice and catch a dropped ruler.

Ways to Teach It
Build two neurons with pipe cleaners; move a lightning-bolt card down an axon, then pass bead neurotransmitters across the synapse.
Ask: Why might a loud alarm make you turn your head before you work out what it means? Have students trace the signals in writing.
Give pairs shuffled cards labeled dendrite, cell body, axon, terminal, neurotransmitter, and receptor; have them order the cards and explain each step.
Run a ruler-drop reaction test, then have students sketch how signals pass between neurons as they see and grab the ruler.
