Comparing Two Life Cycles

Comparing Two Life Cycles

This is a culminating activity for use following the study of basic life cycle concepts. Successful completion of this task will require students to:

- Access the World Wide Web
- Research the life cycles of a frog and a butterfly.
- Complete a Venn Diagram analysis of the similarities and differences between these two life cycles.

The primary purpose of the task is to give learners a chance to gain a deeper understanding of the life cycle process and to use the Web as a resource for learning.

The activity should start with a review of key terminology behind the life cycle.

Student Task

Congratulations! You have just received your first research grant as an intern scientist at the highly prestigious, Middletown Life Cycle Research Center! Your grant award requires you to make a determination regarding what are the key similarities and differences between two common animal life cycles. Your findings will lead to further investigations into the history and functions of species in the animal kingdom and, if successful, will almost certainly lead to a Nobel Prize in science. In order to accomplish this task you need to search resources on the World Wide Web so you can compare and contrast the life cycles of two animal families (amphibians and insects).

Process and Directions

1. To begin you must log onto the internet and use the identified web pages so you can answer the following focus questions:

  • What is the life cycle of an insect?
  • What is the life cycle of an amphibian?

To answer these questions, go to the following web sites, read and review what you see, and then fill in the appropriate spaces in the Research Grid.

For the butterfly - go to:

For the frog - go to (once you get there, you will need to click on the "Life Cycles of Frogs" link - it will be in red - 8th topic in the list)

2. Using your completed Research Grid, compare the information for by filling in the Venn Diagram to demonstrate your excellent scientific analysis. Be sure to use titles and labels. If you really want that Nobel Prize and all of the world wide attention that goes with it, you may want to use colors and pictures to distinguish your work.

3. Check your work by reviewing the Student Assessment Sheet and then hand your two worksheets into your teacher!
