Polar Bears International is a nonprofit organization dedicated to raising awareness about polar bear populations and conservation of their habitat. One of the ways that PBI strives toward that goal is through educational outreach programs like Tundra Connections. Tundra Connections is a series of live webcasts from the Arctic tundra in which viewers have the opportunity to ask questions of polar bear and climate change scientists. The current webcast series has ended, but the webcast video archives can be viewed now.

Applications for Education
In addition to the webcasts and webcast video archives, Polar Bears International offers free lesson plans. PBI’s educational tools section (separate from lesson plans) offers handbooks, quizzes, posters, and many links to external sites related to the study of polar bears.
