  • Transfer of Energy
    • Energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, sound, nuclei, and the nature of a chemical. (5-8)
    • Energy is transferred in many ways. (5-8)
    • Heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature. (5-8)

• 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 world has many different environments, and distinct environments support the life of different types of organisms. (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.
    • All organisms cause changes in the environment where they live. Some of these changes are detrimental to the organism or other organisms, whereas others are beneficial.
    • Humans depend on their natural and constructed environments. Humans change environments in ways that can be either beneficial or detrimental for themselves and other organisms.
  • Structure and function in living systems
    • Living systems at all levels of organization demonstrate the complementary nature of structure and function (5-8)

    • All organisms are composed of cells--the fundamental unit of life (5-8)
    • Most organisms are single cells; other organisms, including humans, are multicellular. (5-8)
    • Specialized cells perform specialized functions in multicellular organisms. (5-8)
    • Groups of specialized cells cooperate to form a tissue, such as a muscle. (5-8)
    • Different tissues are in turn grouped together to form larger functional units, called organs. (5-8)
    • Each type of cell, tissue, and organ has a distinct structure and set of functions that serve the organism as a whole. (5-8)
    • The human organism has systems for digestion, respiration, reproduction, circulation, excretion, movement, control, and coordination, and for protection from disease. These systems interact with one another. (5-8)
  • Reproduction and heredity
    • Reproduction is a characteristic of all living systems; because no individual organism lives forever, reproduction is essential to the continuation of every species. (5-8)
  • Regulation and behavior
    • All organisms must be able to obtain and use resources, grow, reproduce, and maintain stable internal conditions while living in a constantly changing external environment. (5-8)
    • An organism's behavior evolves through adaptation to its environment. (5-8)
    • How a species moves, obtains food, reproduces, and responds to danger are based in the species' evolutionary history (5-8)
  • Populations and ecosystems
    • 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.
    • Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates. (5-8)
  • Diversity and adaptations of organisms
    • Millions of species of animals, plants, and microorganisms are alive today. (5-8)
    • Although different species might look dissimilar, the unity among organisms becomes apparent from an analysis of internal structures, the similarity of their chemical processes, and the evidence of common ancestry. (5-8)
    • Species acquire many of their unique characteristics through biological adaptation, which involves the selection of naturally occurring variations in populations. (5-8)
    • Biological adaptations include changes in structures, behaviors, or physiology that enhance survival and reproductive success in a particular environment (5-8)

• Earth Science
  • Properties of earth materials
    • Earth materials are solid rocks and soils, water, and the gases of the atmosphere.
  • Objects in the sky
    • The sun, moon, stars, clouds, birds, and airplanes all have properties, locations, and movements that can be observed and described.
  • Changes in earth and sky
    • Objects in the sky have patterns of movement.
    • The sun appears to move across the sky in the same way every day, but its path changes slowly over the seasons.
  • Structure of the earth system
    • Major geological events, such as earthquakes, volcanic eruptions, and mountain building, result from the motions of lithospheric plates. (5-8)
    • Land forms are the result of a combination of constructive and destructive forces. (5-8)
    • Constructive forces include crustal deformation, volcanic eruption, and deposition of sediment. (5-8)
    • Destructive forces include weathering and erosion. (5-8)
    • 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)
    • The atmosphere is a mixture of nitrogen, oxygen, and trace gases that include water vapor. (5-8)
    • The atmosphere has different properties at different elevations. (5-8)

  • Earth in the solar system
    • Most objects in the solar system are in regular and predictable motion. (5-8)
    • The motions of most objects in the solar system explain such phenomena as the day, the year, phases of the moon, and eclipses.
    • The sun is the major source of energy for phenomena on the earth's surface, such as growth of plants, winds, ocean currents, and the water cycle. (5-8)
