     4.Knows that soil is a material found on Earth
   Benchmark 2.Knows properties of a number of Earth materials (e.g., rocks, soil, water)
    Knowledge/skill statements
     1.Knows that Earth materials have properties
     2.Knows properties of soil
     3.Knows properties of rocks
     4.Knows properties of water
  Level I (Grade K-2)
   Benchmark 1.Knows that Earth materials consist of solid rocks, soils, liquid water, and the gases of the atmosphere
    Knowledge/skill statements

     4.Knows that the gases of the atmosphere are Earth materials
  Level II (Grade 3-5)
   Benchmark 1.Knows how features on the Earth’s surface are constantly changed by a combination of slow and rapid processes (e.g., slow processes, such as weathering, erosion, transport, and deposition of sediment caused by waves, wind, water, and ice; rapid processes, such as landslides, volcanic eruptions, and earthquakes)
    Knowledge/skill statements
     1.Knows that features on the Earth’s surface are constantly changed by slow processes
     2.Knows that features on the Earth’s surface are constantly changed by rapid processes
     3.Knows that features on the Earth’s surface are constantly changed by weathering
     4.Knows that features on the Earth’s surface are constantly changed by erosion
     5.Knows that features on the Earth’s surface are constantly changed by transport of sediment
     6.Knows that features on the Earth’s surface are constantly changed by deposition of sediment
     7.Knows that features on the Earth’s surface are constantly changed by wind
     8.Knows that features on the Earth’s surface are constantly changed by water
     9.Knows that features on the Earth’s surface are constantly changed by ice
     10.Knows that landslides cause sudden changes in Earth’s features
     11.Knows that volcanic eruptions cause sudden changes in the Earth’s features
     12.Knows that earthquakes cause sudden changes in the Earth’s features
  Level III (Grade 6-8)
   Benchmark 1.Knows that the Earth is comprised of layers including a core, mantle, lithosphere, hydrosphere, and atmosphere
    Knowledge/skill statements
     1.Knows that the Earth is comprised of layers
     2.Knows the center of the Earth contains a core

     5.Knows the hydrosphere consists of the water parts of the Earth
     6.Knows the atmosphere is the gas surrounding the Earth
   Benchmark 2.Knows how land forms are created through a combination of constructive and destructive forces (e.g., constructive forces such as crustal deformation, volcanic eruptions, and deposition of sediment; destructive forces such as weathering and erosion)
    Knowledge/skill statements
     1.Knows that a combination of destructive and constructive forces create land forms
     2.Knows that crustal deformation is a constructive force

     5.Knows that weathering is a destructive force
     6.Knows that erosion is a destructive force
  Level IV (Grade 9-12)
   Benchmark 6.Knows the conditions of Earth that enable it to support life (e.g., force of gravity that enables the planet to retain an adequate atmosphere, intensity of radiation from the Sun that allows water to cycle between liquid and vapor)
    Knowledge/skill statements

     2.Knows that clouds are a major feature of the sky
     3.Knows that the Sun is a major feature of the sky
     4.Knows that the Moon is a major feature of the sky
  Level III (Grade 6-8)
   Benchmark 7.Knows that the Earth is distinguished from other known celestial bodies in that it is the only planet known to harbor life although similar planets might yet be discovered in the universe
    Knowledge/skill statements
     1.Knows that the Earth is different from other known celestial bodies
     2.Knows that similar planets might be discovered in the universe
