HS-LS1-3

SCUSD NGSS Curriculum Guide ==== **HS-LS1-3: Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.**[Clarification Statement: Examples of investigations could include heart rate response to exercise, stomate response to moisture and temperature, and root development in response to water levels.] [//Assessment Boundary: Assessment does not include the cellular processes involved in the feedback mechanism.//] ====

Science Background for the Teacher:
