• Earth Science
  • Properties of earth materials
    • Earth materials are solid rocks and soils, water, and the gases of the atmosphere.
    • Soils have properties of color and texture, capacity to retain water, and ability to support the growth of many kinds of plants, including those in our food supply.
  • Structure of the earth system
    • Destructive forces include weathering and erosion.
    • Old rocks at the earth's surface weather, forming sediments that are buried, then compacted, heated, and often recrystallized into new rock. Eventually, those new rocks may be brought to the surface by the forces that drive plate motions, and the rock cycle continues.
    • Soil consists of weathered rocks and decomposed organic material from dead plants, animals, and bacteria.
    • Soils are often found in layers, with each having a different chemical composition and texture.

• Science as Inquiry
  • Abilities necessary to do scientific inquiry
    • Use appropriate tools and techniques to gather, analyze, and interpret data.
    • Think critically and logically to make the relationships between evidence and explanations.
    • Use mathematics in all aspects of scientific inquiry.
  • Understandings about scientific inquiry
    • Types of investigations include describing objects, events, and organisms; classifying them; and doing a fair test (experimenting).
    • Scientists develop explanations using observations (evidence) and what they already know about the world (scientific knowledge). Good explanations are based on evidence from investigations.

• Teaching Standards
  • Teachers of science plan an inquiry-based science program for their students.
    • Work together as colleagues within and across disciplines and grade levels.
  • Teachers provide students with the time, space, and resources needed to learn science.
    • Create a setting for student work that is flexible and supportive of science inquiry.
    • Make the available science tools, materials, media, and technological resources accessible to students.
  • Teachers of science develop communities of science learners that reflect the intellectual rigor of scientific inquiry.
    • Nurture collaboration among students.
