Topic: Rock cycle 

Science

 Standard 2.  Understands Earth's composition and structure
  Level II (Grade 3-5)
   Benchmark 2.Knows that smaller rocks come from the breakage and weathering of larger rocks and bedrock
    Knowledge/skill statements
     1.Knows that smaller rocks come from the breakage of bedrock
     2.Knows that smaller rocks come from the breakage of larger rocks
     3.Knows that smaller rocks come from the weathering of bedrock
     4.Knows that smaller rocks come from the weathering of larger rocks
  Level III (Grade 6-8)
   Benchmark 5.Knows processes involved in the rock cycle (e.g., old rocks at the surface gradually weather and form sediments that are buried, then compacted, heated, and often recrystallized into new rock; this new rock is eventually brought to the surface by the forces that drive plate motions, and the rock cycle continues)
    Knowledge/skill statements
     1.Knows that new rock is brought to the surface by the forces that drive plate motions in the rock cycle
     2.Knows that old rocks weather to form sediment in the rock cycle
     3.Knows that sediment is buried in the rock cycle
     4.Knows that sediment is compacted in the rock cycle
     5.Knows that sediment is heated in the rock cycle
     6.Knows that sediment is recrystallized into new rock in the rock cycle
   Benchmark 6.Knows that sedimentary, igneous, and metamorphic rocks contain evidence of the minerals, temperatures, and forces that created them
    Knowledge/skill statements
     1.Knows that sedimentary rocks contain evidence of the minerals that created them
     2.Knows that sedimentary rocks contain evidence of the temperatures that created them
     3.Knows that sedimentary rocks contain evidence of the forces that created them
     4.Knows that igneous rocks contain evidence of the minerals that created them
     5.Knows that igneous rocks contain evidence of the temperatures that created them
     6.Knows that igneous rocks contain evidence of the forces that created them
     7.Knows that metamorphic rocks contain evidence of the minerals that created them
     8.Knows that metamorphic rocks contain evidence of the temperatures that created them
     9.Knows that metamorphic rocks contain evidence of the forces that created them
   Benchmark 7.Knows how successive layers of sedimentary rock and the fossils contained within them can be used to confirm the age, history, and changing life forms of the Earth, and how this evidence is affected by the folding, breaking, and uplifting of layers
    Knowledge/skill statements
     1.Knows how successive layers of sedimentary rocks are used to confirm the age of the Earth
     2.Knows how successive layers of sedimentary rocks are used to confirm the history of the Earth
     3.Knows how successive layers of sedimentary rocks are used to confirm the changing life forms on the Earth
     4.Knows how the folding of rock layers affect the evidence of the Earth’s history
     5.Knows how the breaking of rock layers affect the evidence of the Earth’s history
     6.Knows how the fossils in sedimentary rocks are used to confirm the age of the Earth
     7.Knows how the fossils in sedimentary rocks are used to confirm the history of the Earth
     8.Knows how the fossils in sedimentary rocks are used to confirm changing life forms on the Earth
     9.Knows how the uplifting of rock layers affects the evidence of the Earth’s history
  Level IV (Grade 9-12)
   Benchmark 4.Knows that throughout the rock cycle (e.g., formation, weathering, sedimentation, reformation), the total amount of material stays the same as its form changes
    Knowledge/skill statements
     1.Knows that throughout the formation process of the rock cycle, the amount of material remains the same
     2.Knows that throughout the weathering process of the rock cycle, the amount of material remains the same
     3.Knows that throughout the sedimentation process of the rock cycle, the amount of material remains the same
     4.Knows that throughout the reformation process of the rock cycle, the amount of material remains the same
