• Life Science
  • The characteristics of organisms
    • Organisms have basic needs. For example, animals need air, water, and food; plants require air, water, nutrients, and light. (K-4)
    • Organisms can survive only in environments in which their needs can be met. (K-4)
    • Each plant or animal has different structures that serve different functions in growth, survival, and reproduction. For example, humans have distinct body structures for walking, holding, seeing, and talking. (K-4)
    • The behavior of individual organisms is influenced by internal cues (such as hunger) and by external cues (such as a change in the environment). (K-4)
  • Life cycles of organisms
    • Plants and animals have life cycles that include being born, developing into adults, reproducing, and eventually dying. The details of this life cycle are different for different organisms. (K-4)
    • Plants and animals closely resemble their parents. (K-4)
  • Organisms and environments
    • All animals depend on plants. Some animals eat plants for food. Other animals eat animals that eat the plants.
    • An organism's patterns of behavior are related to the nature of that organism's environment, including the kinds and numbers of other organisms present, the availability of food and resources, and the physical characteristics of the environment.
  • Structure and function in living systems
    • Living systems at all levels of organization demonstrate the complementary nature of structure and function (5-8)

    • Most organisms are single cells; other organisms, including humans, are multicellular. (5-8)
    • Cells carry on the many functions needed to sustain life. They grow and divide, thereby producing more cells. (5-8)
    • This requires that cells take in nutrients, which they use to provide energy for the work that cells do and to make the materials that a cell or an organism needs. (5-8)
    • Specialized cells perform specialized functions in multicellular organisms. (5-8)

    • Behavior is one kind of response an organism can make to an internal or environmental stimulus. (5-8)
    • A behavioral response requires coordination and communication at many levels, including cells, organ systems, and whole organisms.

    • Decomposers, primarily bacteria and fungi, are consumers that use waste materials and dead organisms for food. (5-8)
    • Food webs identify the relationships among producers, consumers, and decomposers in an ecosystem. (5-8)
    • For ecosystems, the major source of energy is sunlight. (5-8)
    • The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition.
    • Lack of resources and other factors, such as predation and climate, limit the growth of populations in specific niches in the ecosystem. (5-8)
  • Diversity and adaptations of organisms
    • Millions of species of animals, plants, and microorganisms are alive today. (5-8)

• Earth Science
  • Properties of earth materials
    • Earth materials are solid rocks and soils, water, and the gases of the atmosphere.

    • Water, which covers the majority of the earth's surface, circulates through the crust, oceans, and atmosphere in what is known as the "water cycle." (5-8)
    • Water evaporates from the earth's surface, rises and cools as it moves to higher elevations, condenses as rain or snow, and falls to the surface where it collects in lakes, oceans, soil, and in rocks underground. (5-8)
    • Clouds, formed by the condensation of water vapor, affect weather and climate. (5-8)
  • Earth's history
    • The earth processes we see today, including erosion, movement of lithospheric plates, and changes in atmospheric composition, are similar to those that occurred in the past. (5-8)
