Natural Selection: Three Models

How does natural selection work? Students weigh in on the plausibility of three different models. The purpose is to get students' first impressions and start them thinking about natural selection. They will revisit these models later in the module.

1. Give each student a copy. Working individually, students should fill out questions 1 & 2 only.
2. Collect the copies, but don’t grade them.
3. Return the copies to students as part of Weigh the Models, the module’s final activity. This will give students an opportunity to see how their thinking has changed.
