Grade 9
HS-LS1-2
Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
October 1, 2018HS-LS1-3
Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
October 1, 2018HS-LS1-4
Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
October 1, 2018HS-LS1-5
Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.
October 1, 2018HS-LS1-6
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.
October 1, 2018HS-LS1-7
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.

Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
October 1, 2018HS-LS2-2
Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
October 1, 2018HS-LS2-3
Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobicand anaerobic conditions.
October 1, 2018HS-LS2-4
Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
October 1, 2018HS-LS2-5
Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
