Rocks and Minerals

  • Topic:

    In the Rocks and Minerals unit, students learn that rocks are classified by how they form. Students determine the physical properties of rocks and use these characteristics to identify them. The Earth's structure is explored and students learn how wind, water and ice shape and reshape the Earth's land surface.
