Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules.

Performance Expectation

Grade:  High School (9-12)
Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy.

Performance Expectation

Grade:  High School (9-12)
Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.

Performance Expectation

Grade:  High School (9-12)
Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.

Performance Expectation

Grade:  High School (9-12)
Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.

Performance Expectation

Grade:  High School (9-12)
Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.

Performance Expectation

Grade:  High School (9-12)
Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

Performance Expectation

Grade:  High School (9-12)
Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.

Performance Expectation

Grade:  High School (9-12)
Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.*

Performance Expectation

Grade:  High School (9-12)
Evaluate evidence for the role of group behavior on individual and species’ chances to survive and reproduce.
