Product Description
This lab has students observe evolutionary change directly by being “birds” with different “beaks” with which they have to obtain a certain number of seeds to survive. This is a lab that was designed by and is required by New York State. However, I had a serious problem with the version released by the state. In their version, there are multiple types of seeds, birds can migrate instead of dying- it’s a huge, uninformative mess. In my version, there is one type of seeds and no migrating. With only one variable being considered, students have a much easier time grasping the principal being illustrated. (Natural selection.)

Zip file contains: 1. PDF, to guarantee formatting and for easy printing, 2.Word document, to make it easier to edit.
This document is a simplified and cleaned up version of a non-original document available in many other places. I am offering it for free.
