This short assignment is designed for students to work in pairs after a brief lecture introducing the general topics of dinosaurs or hypotheses, or the more specific topic of Stegosaurus. Using the example of Stegosaurus plates, students learn how scientists make hypotheses about the functions of features on extinct life forms. The Lecture Tutorial can also be used in a general sense to help students understand the use of evidence in forming and evaluating hypotheses. They use the observations given to determine which hypothesis is most likely.

Students will be able to explain why the Stegosaurus has plates, and describe how we know the function of peculiar aspects of dinosaurs. Higher-order thinking skills include critical thinking and determining which hypothesis observations support. Working in groups is another skill students develop.
Context for Use
This activity can be used in an introductory historical geology course or dinosaur course of any size with no special equipment necessary. Students in groups complete this 10-15 minute Lecture Tutorial worksheet after a short lecture on the topic during class. Lecture Tutorials are most effective when used frequently in a course.
