Place cutouts of the salamanders on the map, so all may see. This lesson is probably best presented near the end of your unit on genetics, especially if you have covered population genetics. It helps at this time to see some visible features of real populations and how they are distributed as different subspecies in a particular region. This lesson provides and excellent opportunity to show how biology is so nicely integrated by the themes of evolution and the nature of science. Be sure to point these things out to your students.
Teams can combine to answer the discussion questions.
Ask them to take turns coloring in the squares for each subspecies. Students read and proceed as directed in handouts. Class discussion can continue into the third day. For class discussion, you can simply go over their discussion questions, calling on reps from each team randomly or in succession. All needed materials can be downloaded directly.
