This website is dedicated to providing teachers and students with information about the Clover Lab protocol developed by science teachers and Dr. Kenneth Olsen at Washington University in St. Louis, Missouri. Throughout this lab, your students will have the opportunity to study such areas as Mendelian genetics, population genetics, natural selection, and the effects of plant herbivory.

Upon completing these lab activities, students will be able to:

  • Determine whether clover populations located in geographically warmer climates, or cooler climates, are more likely to produce cyanide.
  • Identify the cyanogenesis allele frequencies of your clover populations.
  • Explain how the frequency of cyanide-producing plants in local clover populations varies depending on the location of the plants.
  • Compare and contrast data to similar climates and more extreme climates across the country using data gathered by other participating teachers and students.

By registering with this website, teachers and their students will be able to participate in ongoing research guided by Dr. Olsen at Washington University in St. Louis, Missouri. Dr. Olsen will use the data collected by teachers and their students as he integrates molecular and ecological genetics to examine the origin and evolution of this adaptive polymorphism.

For your participation you will receive, at no charge, a full kit of materials from Dr. Olsen. This kit will allow you to conduct active research using white clover to teach a variety of curriculum topics.
