This CER activity can be done as an introduction or culminating activity. The activity reinforces concepts in population ecology like carrying capacity and limiting factors. Students will graph and analyze data about the Kaibab deer population at the beginning of the 20th century – a herd of deer living near the Grand Canyon. In an attempt to preserve this herd, humans interfered with the natural processes in ecosystem leading to significant changes in the deer population. Students will graph deer population data, read a short article about the changes to the Kaibab deer ecosystem, and then create an argument with C-E-R to explain whether the attempt to preserve this herd was successful or not.
Great no prep activity! Just print and go! Perfect for a Sub lesson.

This comes from my “Quick and Cl-Ev-R” series. Each activity is designed for students to practice writing scientific arguments with Claim, Evidence, and Reasoning based on real world data and experiences. Each activity includes a quick hands on activity or demonstration, data collection, and corresponding reading focusing on the scientific concepts presented in the activity.
