Every biological fact has a story behind it. The story helps us understand how the fact is justified. It also tells us how science is done. If we do not know this, we remain ignorant of how scientists work and how important scientific discoveries have been made.
Science is complex and richly textured.
The following exercises and case studies illustrate different ways that biologists approach research, and ask students to think critically about scientific issues affecting our daily lives. The site will be maintained and updated by Joel Hagen periodically, so check back for new exercises. If you have ideas for WWW exercises, use case history exercises in your class, or have feedback, send it to Joel Hagen for possible inclusion at this site.
