TEST ITEM SPECIFICATIONS

  • Reporting Category: Life Science
  • Item Type(s): This benchmark will be assessed using: MC item(s)
    Also Assesses
    SC.7.L.15.1 Recognize that fossil evidence is consistent with the scientific theory of evolution that living things evolved from earlier species.

    SC.7.L.15.3 Explore the scientific theory of evolution by relating how the inability of a species to adapt within a changing environment may contribute to the extinction of that species.

  • Clarification :
    Students will identify and/or explain ways in which genetic variation and environmental factors contribute to evolution by natural selection and diversity of organisms.

    Students will identify and/or explain ways in which fossil evidence is consistent with the scientific theory of evolution.

    Students will identify and/or explain how a species’ inability to adapt may contribute to the extinction of that species.
  • Content Limits :
    Items will not address topics such as speciation, genetic drift, or gene pools.

    Items will not assess or address hominid evolution or primate fossils.

    Items assessing fossil evidence should focus on progressions over time/evolution from earlier species and/or the idea that not all species alive today were alive in the past.

    Items will not assess fossils in the context of relative dating or plate tectonics/continental movement.
  • Stimulus Attributes :
    None specified
  • Response Attributes :
    None specified
  • Prior Knowledge :
    Items may require the student to apply science knowledge described in the NGSSS from lower grades. This benchmark requires prerequisite knowledge from SC.5.L.15.1 and SC.5.L.17.1.
