HS-LS1-2 From Molecules to Organisms: Structure & Processes
|
Students who demonstrate understanding can: Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms. |
Clarification Statement: Emphasis is on the levels of organization including cells, tissues, organs, and systems of an organism.
|
Assessment Boundary: Assessment does not include interactions and functions at the molecular or chemical level.

Disciplinary Core Ideas
|
Systems and System Models:
-
Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions— including energy, matter, and information flows—within and between systems at different scales.
|
Developing and Using Models:
- Modeling in 9–12 builds on K–8 and progresses to using, synthesizing, and developing models to predict and show relationships among variables between systems and their components in the natural and designed worlds.
- Develop and use a model based on evidence to illustrate the relationships between systems or between components of a system.
|
Structure and Function:
- Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level.
