• Physical Science
  • Light, heat, electricity, and magnetism
    • Light can be reflected by a mirror, refracted by a lens, or absorbed by the object. (K-4)

• 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 provides the light and heat necessary to maintain the temperature of the earth.
  • Changes in earth and sky
    • Weather can be described by measurable quantities, such as temperature, wind direction and speed, and precipitation.
  • Structure of the earth system
    • 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 has different properties at different elevations. (5-8)
    • Clouds, formed by the condensation of water vapor, affect weather and climate. (5-8)
    • Global patterns of atmospheric movement influence local weather. (5-8)
    • Oceans have a major effect on climate, because water in the oceans holds a large amount of heat. (5-8)
  • Earth in the solar system
    • 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)
  • Energy in the earth system
    • The sun is the major external source of energy. (9-12)
    • Global climate is determined by energy transfer from the sun at and near the earth's surface. (9-12)
    • The greenhouse effect is the warming effect on the air caused by heat rising from the surface of the Earth and being trapped by gases in the troposphere. (9-12)

• Science as Inquiry
  • Abilities necessary to do scientific inquiry
    • Use appropriate tools and techniques to gather, analyze, and interpret data.
    • Develop descriptions, explanations, predictions, and models using evidence.
    • Think critically and logically to make the relationships between evidence and explanations.

• Science in Personal and Social Perspectives
  • Changes in environments
    • Pollution is a change in the environment that can influence the health, survival, or activities of organisms, including humans.
  • Natural hazards
    • Internal and external processes of the earth system cause natural hazards (disasters), events that change or destroy human and wildlife habitats, damage property, and harm or kill humans. (5-8)
