Before doing this lesson, it is a good idea to make a poster to use as an example. Be sure to make the poster three dimensional.
Explain that today students will be creating a life cycle poster. Explain to students that the posters should be three dimensional. Show them the example that you created. Pass out the poster board, markers, and art materials. Some excellent art materials to use include pom poms, pipe cleaners, and pieces of sequins.
Have students write the name of each stage and illustrate it. Have the life cycle go in a circular pattern with an arrow in between each stage. Depending on the age group doing this lesson, you can even have students write a brief description of each stage of the insect life cycle. Allow students to get creative as they make their posters.
