4-LS1-2
The standard
Use a model to describe that animals' receive different types of information through their senses, process the information in their brain, and respond to the information in different ways.
Next Generation Science Standards
What this standard means
Students need to explain a simple information pathway: an animal senses something, the brain processes that information, then the animal responds. They should use a model, such as a flow chart, labeled diagram, or cause-and-effect chain, to show how sight, sound, smell, touch, or taste can lead to different actions.
Mastery looks like choosing the right sense, naming the brain as the processing part, and matching the response to the information. Students often skip the brain step, mix up senses, or say the animal “just knows” what to do. Keep the focus on information transfer, not brain anatomy.
Ways to teach it
- Have students sort animal scenario cards into sense, brain processing, and response columns, then draw one as a labeled flow chart.
- Ask students to write: How would a rabbit respond differently to smelling a fox versus hearing a falling branch?
- Show a picture of an animal reacting, then ask students to complete: sense used, information received, brain processes, response.
- Connect to crosswalks by modeling how people see a walk signal, process its meaning, and decide whether to step into the street.
