2. History of Rock - Assessments


  1. The summary tables and data sheets may be collected and graded.
  2. A quiz on different rocks and their formation may be appropriate. For example:

Match each statement to the type of rock being described:
a) sedimentary
b) igneous
c) metamorphic

______     1. This type of rock is formed when eroded pieces of other rocks and minerals are compacted and cemented together.

______    10. The size of the particles that make up this type of rock tells you how fast the water was moving when the particles were deposited.

Going Further

  1. Now that students have some experience with making observations of rocks, give each student a mystery mineral to observe, identify, and research. They should complete a Rock History Data Sheet on it and use mineral identification guides to discover the identity and history of their mineral. To up the challenge, give students minerals or metals with a more complicated history like silver ore or a geode.
  2. To learn more about sedimentary rocks, try the Layers upon Layers lesson or make your own sedimentary rocks, described the Going Further section of the Crayon Rock Cycle lesson.
