See what kind of information Wendell uses to profile cockroaches as a guide. Older students can create a documentary of their convention using a video camera or still photos inserted into presentation software, or make an annotated scrapbook like Wendell's. The illustrators in your class will have a great time charting the stages of insect metamorphosis. If they are fortunate enough to be able to observe a complete life cycle of an insect, such as a butterfly, encourage them to create scientific illustrations from direct observation. When that is not possible, students can use other illustrated resources as models for their illustrations.
Metamorphosis is a good topic for introducing the format of a flow chart as a graphic illustrator.
Also see Operation Mexfly for an additional activity which relates to insect life cycles. Yes, it's a truly yucky subject, but if your school has a problem with lice, make it an educational, if itchy, experience. A good opportunity to talk about insect adaptation, and why it's important to try to prevent future outbreaks. Look at Wendell's Roach Removal Report for comparison to another insect. Have students list their hypotheses, then read more about it.
