Assessments
  • Assessment Anchor - BIO.B.4

    Ecology
    • Anchor Descriptor - BIO.B.4.1

      Describe ecological levels of organization in the biosphere.
      • Eligible Content - BIO.B.4.1.1 Describe the levels of ecological organization (i.e., organism, population, community, ecosystem, biome, biosphere).
      • Eligible Content - BIO.B.4.1.2 Describe characteristic biotic and abiotic components of aquatic and terrestrial ecosystems.
    • Anchor Descriptor - BIO.B.4.2

      Describe interactions and relationships in an ecosystem.
      • Eligible Content - BIO.B.4.2.1 Describe how energy flows through an ecosystem (e.g., food chains, food webs, energy pyramids).
      • Eligible Content - BIO.B.4.2.2 Describe biotic interactions in an ecosystem (e.g., competition, predation, symbiosis).
      • Eligible Content - BIO.B.4.2.3 Describe how matter recycles through an ecosystem (i.e., water cycle, carbon cycle, oxygen cycle, nitrogen cycle).
      • Eligible Content - BIO.B.4.2.4 Describe how ecosystems change in response to natural and human disturbances (e.g., climate changes, introduction of nonnative species, pollution, fires).
      • Eligible Content - BIO.B.4.2.5 Describe the effects of limiting factors on population dynamics and potential species extinction.
  • Assessment Anchor - S4.B.3

    Ecological Behavior and Systems
    • Anchor Descriptor - S4.B.3.1 Identify and describe living and nonliving things in the environment and their interaction.
      • Eligible Content - S4.B.3.1.1 Describe the living and nonliving components of a local ecosystem (e.g., lentic and lotic systems, forest, cornfield, grasslands, city park, playground).
        • Alternate Eligible Content - S4.B.3.1.1a Categorize the parts of an ecosystem as either living or non-living (e.g., forest, city, park).
          Alternate Eligible Content is designed for students assessed using the PA Alternate System of Assessment (PASA). Essentialized Example resources assist teachers in designing instruction that reduces content complexity while maintaining alignment to academic standards.
      • Eligible Content - S4.B.3.1.2 Describe interactions between living and nonliving components (e.g. plants – water, soil, sunlight, carbon dioxide, temperature; animals – food, water, shelter, oxygen, temperature) of a local ecosystem.
    • Anchor Descriptor - S4.B.3.2 Describe, explain, and predict change in natural or human-made systems and the possible effects of those changes on the environment.
      • Eligible Content - S4.B.3.2.1 Describe what happens to a living thing when its habitat is changed.
        Assessments
        Continuum of Activities
      • Eligible Content - S4.B.3.2.2 Describe and predict how changes in the environment (e.g., fire, pollution, flood, building dams) can affect systems.
        Assessments
        Continuum of Activities
      • Eligible Content - S4.B.3.2.3 Explain and predict how changes in seasons affect plants, animals, or daily human life (e.g., food availability, shelter, mobility).
        Assessments
        Continuum of Activities
        • Alternate Eligible Content - S4.B.3.2.3.a Identify how seasons affect trees or animals (e.g., temperature, migration, hibernation).
          Alternate Eligible Content is designed for students assessed using the PA Alternate System of Assessment (PASA). Essentialized Example resources assist teachers in designing instruction that reduces content complexity while maintaining alignment to academic standards.
    • Anchor Descriptor - S4.B.3.3 Identify and describe human reliance on the environment at the individual or the community level.
      • Eligible Content - S4.B.3.3.1 Identify everyday human activities (e.g., driving, washing, eating, manufacturing, farming) within a community that depend on the natural environment.
      • Eligible Content - S4.B.3.3.2 Describe the human dependence on the food and fiber systems from production to consumption (e.g., food, clothing, shelter, products).
      • Eligible Content - S4.B.3.3.3 Identify biological pests (e.g., fungi – molds, plants – foxtail, purple loosestrife, Eurasian water milfoil; animals – aphides, ticks, zebra mussels, starlings, mice) that compete with humans for resources.
      • Eligible Content - S4.B.3.3.4 Identify major land uses in the urban, suburban and rural communities (e.g., housing, commercial, recreation).
      • Eligible Content - S4.B.3.3.5 Describe the effects of pollution (e.g., litter) in the community.
