This lesson follows a flipped learning model where teachers don’t stand before the class and lecture.  Instead, students become grizzly bear scientists and “discover” the answers to real-world research questions through scientific inquiry.

Using real-world demographic data collected over 30 years on grizzly bears in the Greater Yellowstone Ecosystem, students work individually, in three Science Teams, and as a class to determine whether or not this grizzly bear population is biologically ready for delisting.

All program materials are available for free download:
