Introduction

This 55-minute, interactive eTrip features video clips, online activities, and animated illustrations of scientific concepts related to the Yellowstone pronghorn. Viewers are encouraged to investigate the reasons behind the sharp population decline of this animal in the park and to explore past and present management techniques. The eTrip exposes students to ongoing research about pronghorn population dynamics, natural threats, and interactions with other wildlife. Students are given the opportunity to use their critical thinking skills as they weigh the evidence before rendering a verdict as to whether the Yellowstone pronghorn population “is” or “is not” in danger of regional extinction. The Ask an Expert Message Board is available from September 14-16, 2005. Resource experts will be available to answer your students’ questions. The questions and answers will remain accessible after the message board has been deactivated.

For a list of education standards applicable to this field trip, please visit the Standards Page. If time permits, students may wish to attend the Park’s Orientation program before taking this electronic field trip.
