Product Description
This activity is an example of a population of bears changing over time once a predator is introduced. It compares 2 arm variations: hands up or hands down.

Prep for this lab includes copying & laminating sets of bear cards (3 pages per group) OR you can use "Teddy Grahams" crackers. (I stopped using the crackers when I noticed an uneven distribution of hands up & hands down bears... but I wanted to let you know it is another way to complete this lab.)

I have also included the grade sheet I use for our lab notebook set up (available for free download, if you are interested).
