Actions

LS1 From Molecules to Organisms: Structures and Processes

LS2 Ecosystems: Interactions, Energy, and Dynamics

  • LS2.A Interdependent Relationships in Ecosystems

  • LS2.B Cycles of Matter and Energy Transfer in Ecosystems

  • LS2.C Ecosystem Dynamics, Functioning, and Resilience

    • HS-LS2-6 Evaluate 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-LS2-7 Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.

  • LS2.D Social Interactions and Group Behavior

LS3 Heredity: Inheritance and Variation of Traits

LS4 Biological Evolution: Unity and Diversity

  • LS4.A Evidence of Common Ancestry and Diversity

  • LS4.B Natural Selection and Evolution

    • 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-LS4-3 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.

  • LS4.C Adaptation

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

    • 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.

  • LS4.D Biodiversity and Humans

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