Grade Discipline Core Idea
3-5 LS1.A: Structure and function

Organisms have both internal and external macroscopic structures that allow for growth, survival, behavior, and reproduction.
6-8 LS1.A: Structure and function

All living things are made up of cells.  In organisms, cells work together to form tissues and organs that are specialized for particular body functions.
9-12 LS1.A: Structure and function

Systems of specialized cells within organisms help perform essential functions of life. Any one system in an organism is made up of numerous parts.  Feedback mechanisms maintain an organism's internal conditions within certain limits and mediate behaviors.
