In this activity students determine their reaction time using a ruler. This is very interactive way for students to understand how a stimulus creates a response.
Encourage students to complete and see who has a fastest reaction time.
MS-LS1-8: Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or stored as memories
