Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.
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.
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.
Ecosystems: Interactions Energy and Dynamics
Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
Use a mathematical representation to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere atmosphere hydrosphere and geosphere.
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.
Design evaluate and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
Evaluate the evidence for the role of group behavior on individual and species' chances to survive and reproduce.
