HS-LS2-5
From NY Science Standards Wiki
Develop a model to illustrate the role of various processes in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
Clarification statement: Examples of models could include simulations, diagrams, and mathematical models of the carbon cycle (photosynthesis, respiration, decomposition, and combustion).
Assessment boundary: Assessment does not include the specific chemical steps of photosynthesis and respiration.

NGSS Dimensions
Performance expectation HS-LS2-5 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
Science and Engineering Practices
- Developing and Using Models
- Develop a model based on evidence to illustrate the relationships between systems or components of a system.
Disciplinary Core Ideas
- LS2.B: Cycles of Matter and Energy Transfer in Ecosystems
- (NYSED) Photosynthesis and cellular respiration are important components of the carbon cycle, in which carbon is exchanged among the biosphere, atmosphere, hydrosphere, and geosphere through chemical, physical, geological, and biological processes.
- PS3.D: Energy in Chemical Processes
- The main way that solar energy is captured and stored on Earth is through the complex chemical process known as photosynthesis
Crosscutting Concepts
- Systems and System Model
- 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.
