Metamorphic Rocks Lesson Plan

Instructor: Josh Corbat

Josh has taught Earth Science and Physical Science at the High School level and holds a Master of Education degree from UNC-Chapel Hill.

Use this lesson plan to introduce your students to the various processes that form metamorphic rocks. Students will watch a video lesson, create a graphic organizer, and simulate metamorphic rock formation in a hands-on activity.

Learning Objectives

After this lesson, students will be able to:

  • name and define each process that forms metamorphic rock
  • describe each process that forms various types of metamorphic rock


60-90 minutes

Curriculum Standards


Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 9-10 texts and topics.


Analyze the structure of the relationships among concepts in a text, including relationships among key terms (e.g., force, friction, reaction force, energy).


  • Metamorphic rock samples
  • Large number of used crayons
  • Hot glue gun (one for each group; alternatively, students can use other types of glue, but the activity will have to be done over the course of a few days)
  • Heat guns or hair dryers (one for each group)
  • Cardboard (enough for each group to have a 1-foot by 1-foot square)
  • Bricks or other heavy objects


  • Begin the lesson by sending a few samples of metamorphic rock around the room. Try to find a few examples that are very different in appearance and texture.
  • Begin the video lesson Metamorphism of Rocks: Definition, Process & Influencing Factors. Pause the video at 1:30 and discuss the following questions:
    • What is a metamorphic rock?
    • How does a metamorphic rock form?
    • What factors influence the way a metamorphic rock will form? What do these factors do to a rock's appearance and texture?
  • Have students create a simple graphic organizer. Have them create the chart below and fill it out while they watch. Also create one on the board that can be filled in after the video.

Metamorphic Process Definition/Description Rock Example(s)
  • Resume and finish the video. When the video is finished, ask student volunteers to come to the board to fill in the chart. This will allow students to fill in any gaps they may have.
