1
Use mathematical and/or computational representations to support explanations of factors that affect carrying capacities of ecosystems at different scales. EN.LS2.1
2
Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales. EN.LS2.2
4
Use a mathematical representation to support claims for the cycling of matter and the flow of energy among organisms in an ecosystem. EN.LS2.4
6
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. EN.LS2.6
7
Design, evaluate, and refine a solution for reducing the impact of human activities on the environment and biodiversity.* EN.LS2.7

6
Use evidence to construct an explanation that describes how a designed solution mitigates adverse impacts of human activity on biodiversity.* EN.LS2.6

1
Develop a model to illustrate how Earth’s internal and surface processes operate at different scales of space and time to form continental and ocean-floor features. EN.ESS2.1
2
Analyze geoscience data to make the claim that one change to Earth’s surface can create feedback and interactions that cause changes to other Earth systems. EN.ESS2.2
3
Develop a model based on evidence of Earth’s interior to describe the cycling of matter by thermal convection. EN.ESS2.3
4
Analyze and interpret data to explore how variations in the flow of energy into and out of Earth’s systems cause changes to the atmosphere and climate. EN.ESS2.4
5
Plan and conduct investigations of how the structure and resulting properties of water interact with the Earth’s materials and surface processes. EN.ESS2.5
6
Develop a quantitative model to describe the cycling of carbon among the hydrosphere, atmosphere, geosphere, and biosphere. EN.ESS2.6
7
Engage in argument from evidence for how the simultaneous co-evolution of Earth’s systems and life on Earth led to periods of stability and change over geologic time. EN.ESS2.7

1
Construct an explanation based on evidence for how the availability of natural resources, occurrences of natural hazards, and changes in climate affect human activity.* EN.ESS3.1
2
Evaluate competing design solutions for developing, managing, and utilizing energy and mineral resources based on cost-benefit ratios on large and small scales.* EN.ESS3.2
3
Use computational simulations to illustrate changes in the relationships between natural resources, human populations, and biodiversity and their sustainability within Earth’s systems.* EN.ESS3.3
4
Evaluate design solutions for a major global or local environmental problem that reduces or stabilizes the impacts of human activities on natural systems.*EN.ESS3.4
