Lesson 7 Science Vocabulary

Stimulus – something that happens (the frog jumping) Example: a sudden noise, light, heat

Response – something your body does when the stimulus happens (like trying to catch the frog) Example: smiling when you see a friend, stopping at a red light, crying at something sad, pulling your hand away from something hot.

For the stimulus/response process, your eyes, ears, brain, nerves and muscles all work together. Example: jumping when you hear a loud noise.

Stimulus/response times are affected by age, ability, and health.
