The lesson is a further in-depth study of metamorphosis, both complete and incomplete, with the focus on insects and amphibians.  Most students are familiar of the changes an animal experiences as it grows from an egg to adult, but may not clearly understand the stages and how some animals mature differently than others.  It is recommended teachers use one of more of the videos showing the stages of metamorphosis.

Metamorphosis Lesson Plan Includes:

  • Full Teacher Guidelines with Creative Teaching Ideas
  • Instructional Content Pages about Metamorphosis
  • Hands-on homework activities
  • Answer Keys
  • Common Core State Standards
  • Many Additional Links and Resources
  • Built for Grades 3-5 but can be adapted for other grade levels.

The lesson includes an in-depth study of metamorphosis, both complete and incomplete, with a focus on insects and amphibians. The lesson begins by describing various life cycles of living organisms, and then describes a completely different life cycle, metamorphosis. The lesson describes, with illustrations, each part of the life cycle of both insects and amphibians with relevant vocabulary defined. It is recommended teachers use one or more of the videos showing the stages of metamorphosis.

Sample Classroom Procedure / Teacher Instruction: 

  1. Display an image of a human, chicken, frog, butterfly, and grasshopper. Ask students:  What is the same and different about each of the living things?
  2. Allow for responses and discussion. Further ask students: What is the difference between how the animals grow from birth to adult?
  3. Allow for responses and discussion. (Students should have given responses related to metamorphosis, and if not, give hints about the changes and allow for further responses and discussion.)  Introduce Metamorphosis.
  4. Distribute Metamorphosis content pages. Read and review the information with the students.  Save the final question for the lesson closing.  It is highly recommended students view one or more of the resource videos during the lesson.  Use the additional resources to enhance understanding.
  5. Distribute Activity page. Read and review the instructions.  Encourage students to be creative and include conversations between like and different organisms.  Ask students to “think” like the amphibian or insect they have chosen.  During the writing process, pair students to review each other’s work prior to completing the final copy.  Students will then need access to the Internet or other sources for images, or they may draw related pictures.
  6. Once completed with the stories and drawings, students will share with the class, reading the story aloud and displaying the images/drawings.
  7. Distribute Practice page. Check and review the students’ responses.
  8. Distribute the Homework page. The next day, check and review the students’ responses.  Students correct false responses.
  9. In closing, ask students: Which living organism do you find most interesting as it grows from birth to adult?  Why?
  10. Allow for responses and discussion. (Students may also choose organisms that do not go through metamorphosis.)
