This set of worksheets accompanies this peppered moth simulation website: http://peppermoths.weebly.com/
Ignore the link on the worksheet. It is old.
The worksheets force the students to read background information regarding peppered moths and answer questions. Then, students play the role of a predator (bird) and eat moths in different environments. The worksheet has them collect data, calculate an average, and graph results. The worksheet also includes conclusion questions. I used this as a lab with high school biology students.
Full answer key, including sample data, included.
