The Rock Pocket Mice of southwestern United States have demonstrated a very clear and interpretable case for microevolution. This assignment requires students to take the roles of scientists and use traps at two simulated locations to determine what is happening to the populations of dark coated and light coated mice. The trap data has been mixed up and the students need to try to find a logical chronological order for it and explain their reasoning. Students will then graph the data provided.
After discussing their conclusions, students will view and interact with the HHMI website video (linked to the PPT) of “The Making of the Fittest” and respond to questions about the actual cause of the rock pocket mouse change over time.
This assignment requires group work and discuss as well as full class and individual work.
Student handouts are half sheet in length.
Attached to the end of the student handout are the rock pocket mouse trap data cards and traps (fold in half and staple to make a simple envelope for carrying the trap data cards.
