Develop a quantitative model to describe the cycling of carbon among the hydrosphere, atmosphere, geosphere, and biosphere.
Clarification statement: Emphasis is on modeling biogeochemical cycles that include the cycling of carbon through the ocean, atmosphere, soil, and biosphere (including humans), providing the foundation for living organisms.
Note: this is a performance expectation for both HS Earth & Space Science and HS Biology. For biology, the focus is on "the biochemistry aspects of carbon cycling". For Earth & Space Science, the focus is on "physical and chemical aspects of the geochemical cycling of carbon" (as per the NYSED high school course maps).

Performance Level Descriptions
Every Regents exam question on HS-ESS2-6 is written to match one of the performance level descriptions (PLDs) below.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of HS-ESS2-6.
This section could be expanded upon. You can help out by adding to this section.
NGSS Dimensions
Performance expectation HS-ESS2-6 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Developing and Using Models
- Develop a model based on evidence to illustrate the relationships between systems or between components of a system.
- ESS2.D: Weather and Climate
- Gradual atmospheric changes were due to plants and other organisms that captured carbon dioxide and released oxygen.
- Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate.
- Energy and Matter
- The total amount of energy and matter in closed systems is conserved.
