Biology: Grades 9, 10, 11, 12

From Molecules to Organisms: Structures and Processes

  • HS-LS1-1.

    Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.HS-LS1-1

  • HS-LS1-2.

    Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.HS-LS1-2

  • HS-LS1-3.

    Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.HS-LS1-3

  • HS-LS1-4.

    Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.HS-LS1-4

  • HS-LS1-5.

    Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.HS-LS1-5

  • HS-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.HS-LS1-6

  • HS-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.HS-LS1-7

Ecosystems: Interactions, Energy and Dynamics

  • HS-LS2-1.

    Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.HS-LS2-1

  • HS-LS2-2.

    Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.HS-LS2-2

  • HS-LS2-3.

    Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.HS-LS2-3

  • HS-LS2-4.

    Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.HS-LS2-4

  • HS-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.HS-LS2-5

  • HS-LS2-6.

    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.HS-LS2-6

  • HS-LS2-7.

    Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.HS-LS2-7

  • HS-LS2-8.

    Evaluate the evidence for the role of group behavior on individual and species' chances to survive and reproduce.HS-LS2-8

Heredity: Inheritance and Variation of Traits

  • HS-LS3-1.

    Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.HS-LS3-1

  • HS-LS3-2.

    Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.HS-LS3-2

  • HS-LS3-3.

    Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.HS-LS3-3

Biological Evolution: Unity and Diversity

  • HS-LS4-1.

    Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.HS-LS4-1

  • HS-LS4-2.

    Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.HS-LS4-2

  • HS-LS4-3.

    Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.HS-LS4-3

  • HS-LS4-4.

    Construct an explanation based on evidence for how natural selection leads to adaptation of populations.HS-LS4-4

  • HS-LS4-5.

    Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.HS-LS4-5

  • HS-LS4-6.

    Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.HS-LS4-6
