Pennsylvania Academic Standards for Environment and Ecology
4.7: Threatened, Endangered and Extinct Species


This page contains the criteria for teaching Threatened, Endangered and Extinct Speciesthat were developed in the PA Academic Standards. Clicking on a grade levelbelow will skip directly to the criteria for educators teaching at or belowthat grade. Clicking on the criteria will lead to all the teaching resourcesrelated to it.


Fourth Grade |Seventh Grade |Tenth Grade |Twelfth Grade



Grade 4 : Threatened, Endangered and Extinct Species (4.7.4)
Fourth Grade: 4.7A Fourth Grade: 4.7B Fourth Grade: 4.7C
Identify differences in living things.
  • Explain why plants and animals are different colors, shapes and sizes and how these differences relate to their survival.
  • Identify characteristics that living things inherit from their parents.
  • Explain why each of the four elements in a habitat is essential for survival.
  • Identify local plants or animals and describe their habitat.
Know that adaptations are important for survival.
  • Explain how specific adaptations can help a living organism to survive.
  • Explain what happens to a living thing when its food, water, shelter or space is changed.
Define and understand extinction.
  • Identify plants and animals that are extinct.
  • Explain why some plants and animals are extinct.
  • Know that there are local and state laws regarding plants and animals.



Grade 7 : Threatened, Endangered and Extinct Species (4.7.7)
Seventh Grade: 4.7A Seventh Grade: 4.7B Seventh Grade: 4.7C
Describe diversity of plants and animals in ecosystems.
  • Select an ecosystem and describe different plants and animals that live there.
  • Identify adaptations in plants and animals.
  • Recognize that adaptations are developed over long periods of time and are passed on from one generation to the next.
  • Understand levels of ecosystem organization (e.g., individuals, populations, species).
    • Explain how species of living organisms adapt to their environment.
      • Explain the role of individual variations in natural selection.
      • Explain how an adaptation is an inherited structure or behavior that helps an organism survive and reproduce.
      • Describe how a particular trait may be selected over time and account for a species' adaptation.
      • Compare and contrast animals and plants that have very specific survival requirements with those that have more general requirements for survival for survival.
      • Explain how living things respond to changes in their environment.
      • Explain how one species may survive an environmental change while another might not.
      Explain natural or human actions in relation to the loss of species.
      • Identify natural or human impacts that cause habitat loss.
      • Explain how habitat loss can affect the interaction among species and the population of a species.
      • Analyze and explain the changes in an animal population over time.
      • Explain how a habitat management practice affects a population.
      • Explain the differences among threatened, endangered and extinct species.
      • Identify Pennsylvania plants and animals that are on the threatened or endangered list.
      • Describe state laws passed regarding threatened and endangered species in Pennsylvania.
      • Explain why one species may be more susceptible to becoming endangered than another species.

       



      Grade 10 : Threatened, Endangered and Extinct Species (4.7.10)
      Tenth Grade: 4.7A Tenth Grade: 4.7B Tenth Grade: 4.7C
      Explain the significance of diversity in ecosystems.
      • Explain the role that specific organisms have in their ecosystem.
      • Identify a species and explain what effects its increase or decline might have on the ecosystem.
      • Identify a species and explain how its adaptations are related to its niche in the environment.
      Explain how structure, function and behavior of plants and animals affect their ability to survive.
      • Describe an organism's adaptations for survival in its habitat.
      • Compare adaptations among species.
      Identify and explain why adaptations can lead to specialization.
      • Explain factors that could lead to a species' increase or decrease.
      • Explain how management practices may influence the success of specific species.
      • Identify and explain criteria used by scientists for categorizing organisms as threatened, endangered or extinct.



      Grade 12 : Threatened, Endangered and Extinct Species (4.7.12)
      Twelfth Grade: 4.7A Twelfth Grade: 4.7B Twelfth Grade: 4.7C
      Analyze biological diversity as it relates to the stability of an ecosystem.
      • Examine and explain what happens to an ecosystem as biological diversity changes.
      • Explain the relationship between species' loss and bio-diversity.
      • Examine and explain how a specialized interaction between two species may affect the survival of both species.
      Examine the effects of extinction, both natural and human caused, on the environment.
      • Predict how human or natural action can produce change to which organisms cannot adapt.
      • Identify species that became extinct through natural causes and explain how that occurred.
      • Identify a species that became extinct due to human actions and explain what occurred.
      Analyze the effects of threatened, endangered or extinct species on human and natural systems.
      • Identify and explain how a species' increase, decline or elimination affects the ecosystem and/or human social, cultural and economic structures.
      • Explain why natural populations do not remain constant.
      • Analyze management strategies regarding threatened or endangered species.
      • Identify laws, agreements or treaties at national or international levels regarding threatened or endangered species.
      • Analyze the role of zoos and wildlife preserves on species that have been identified as threatened or endangered.
      • Examine the influence of wildlife management in preserving different species in Pennsylvania (e.g., bobcat, elk, bald eagle).
