Survival Strategies (Teacher Edition)by: Elizabeth Rice, Marianne Krasny, and Margaret E. Smith

Book ChapterDigital resources are stored online in your NSTA Library.

This chapter focuses on ecological principles of plant defenses and insect adaptations to these defenses. Insects either are generalists, often deterred by plant chemical defense compounds, or they are specialists that are attracted to the defense compound. The questions in the chapter focus on ecology and evolution. Using a process of guided inquiry, students design their own experiment to test the effects of a bitter gene in cucumbers on a population of cucumber beetles.

Students can review food webs while exploring the relationships between genetics, natural selection, and coevolution. I cannot wait to try this experiment with my high school biology next year. I am going to have my students perform the experiment before reading the chapter. I think they would be more engaged and would learn more from the experiment. This exercise is perfect for a high school or college setting.
