Performance expectationDevelop a model to illustrate the role of various processes in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
Examples of models could include simulations, diagrams, and mathematical models of the carbon cycle (photosynthesis, respiration, decomposition, and combustion).
Assessment does not include the specific chemical steps of photosynthesis and respiration.
Every item written to HS-LS2-5 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.
Developing and Using Models
Phenomenon stimulus, connected items across the required types, answer key, rubric and figures drawn deterministically from a structured spec — in the format your students will sit.
