Instructional Ideas

  • Consider having individuals complete the Rock Venn Diagram, then compare them within small or large group discussion
  • During the making of sedimentary rocks lab, pose questions about the conditions in which the three types of rocks would be made; linking rock characteristics and rock origins is a key concept
Classroom Considerations

  • Depending on their level of prior knowledge, class may complete all assignments prior to the suggested two-week time frame
  • Try to include as many "local" rocks within the framework as you can, particularly if many of your class members live in the city
Pros

  • Observing rock formation in class brings this subject matter to life, shattering the misconception that all rocks are pretty much the same
  • Includes all printable materials
Cons

  • Not having a large, diverse set of sedimentary rock specimens reduces It's Sedimentary, My Dear Watson to an online research activity
