A WebQuest for Biology Russell Hendricks, Charlotte Prep, Florida Introduction Today we are going to learn about a topic that most of you love, Dinosaurs! Although we do not learn that much about them in class, if you become a biologist considerable time is spent learning all about them. We will be using a learning model called a webquest. In using this tool, you will work in groups of three to answer the question, What killed the dinosaurs? To solve this mystery, you must go on a quest, back in time to the Cretaceous Period. Be careful, hungry velociraptors may be around any corner! You will examine online resources to answer the ques- tion, What killed the dinosaurs? The Task You and your team of paleontologists have just been appointed by Harvard University to determine the cause of the extinction of the dinosaurs. The teams will research the possible causes of the extinction event and determine which theory is most plausible. You will need to persuade the other teams and the director of research (the teacher). Be sure to be aware of the shortcomings of the theories you did not choose. The Process • First, read the general resources. Then, each team member will choose one possible cause of extinction to research (impact, volcanic, climate change). Each team member will write a brief summary including the supporting evidence. • The teams will choose the theory that they deem most plausible. • The teams will create a presentation in the medium of their choice. The presentation may be a powerpoint poster, slideshow, or an actual poster. The presentation should persuade readers of the theory that the team chose, as well as present evidence of why other theories fall short. Be sure to review the evaluation section so that your presentation meets the necessary requirements. • The director of research and the other teams will decide which theory is most plausible.
