Limit your search to no more than three grades, subjects, or courses, and ensure that you have selected at least one grade and subject or one course.

Subject Area - 4:
Environment and Ecology
  • Standard Area - 4.5: Humans and the Environment
  • Grade Level - 4.5.4:

    GRADE 4

Standard - 4.5.4.D

Describe a waste stream.

  • Identify sources of waste derived from the use of natural resources.
  • Identify those items that can be recycled and those that can not.
  • Describe how everyday activities may affect the environment

  • Assessment Anchor - BIO.A.4

    Homeostasis and Transport

    • Anchor Descriptor - BIO.A.4.1

      Identify and describe the cell structures involved in transport of materials into, out of and throughout a cell.

      • Eligible Content - BIO.A.4.1.1 Describe how the structure of the plasma membrane allows it to function as a regulatory structure and/or protective barrier for a cell.
      • Eligible Content - BIO.A.4.1.2 Compare and contrast the mechanisms that transport materials across the plasma membrane (i.e., passive transport -- diffusion, osmosis, facilitated diffusion; active transport -- pumps, endocytosis, exocytosis).
      • Eligible Content - BIO.A.4.1.3 Describe how endoplasmic reticulum, Golgi apparatus, and other membrane-bound cellular organelles facilitate transport of materials within cells.
    • Anchor Descriptor - BIO.A.4.2

      Explain mechanisms that permit organisms to maintain biological balance between their internal and external environments.

      • Eligible Content - BIO.A.4.2.1 Explain how organisms maintain homeostasis (e.g., thermoregulation, water regulation, oxygen regulation).
  • Assessment Anchor - S4.B.1

    Structure and Function of Organisms

    • Anchor Descriptor - S4.B.1.1 Identify and describe similarities and differences between living things and their life processes.
      • Eligible Content - S4.B.1.1.1 Identify life processes of living things (e.g., growth, digestion, respiration).
      • Eligible Content - S4.B.1.1.2 Compare similar functions of external characteristics of organisms (e.g., anatomical characteristics: appendages, type of covering, body segments).
      • Eligible Content - S4.B.1.1.3 Describe basic needs of plants and animals (e.g., air, water, food).
      • Eligible Content - S4.B.1.1.4 Describe how different parts of a living thing work together to provide what the organism needs (e.g., parts of plants: roots, stems, leaves).
      • Eligible Content - S4.B.1.1.5 Describe the life cycles of different organisms (e.g., moth, grasshopper, frog, seed-producing plant).
  • Assessment Anchor - S4.B.2

    Continuity of Life

    • Anchor Descriptor - S4.B.2.1 Identify and explain how adaptations help organisms to survive.
      • Eligible Content - S4.B.2.1.1 Identify characteristics for plant and animal survival in different environments (e.g., wetland, tundra, desert, prairie, deep ocean, forest).
      • Eligible Content - S4.B.2.1.2 Explain how specific adaptations can help a living organism survive (e.g., protective coloration, mimicry, leaf sizes and shapes, ability to catch or retain water).
    • Anchor Descriptor - S4.B.2.2 Identify that characteristics are inherited and, thus, offspring closely resemble their parents.
      • Eligible Content - S4.B.2.2.1 Identify physical characteristics (e.g., height, hair color, eye color, attached earlobes, ability to roll tongue) that appear in both parents and could be passed on to offspring.
