Our friends at PBI just launched a contest on My Planet, My Part that encourages students to take action today and be an ambassador for polar bears. Upload your stories, photos, and videos of how you're reducing your carbon footprint at home, school, work, or your community.  The grand prize is a trip for 2 to Churchill, Canada, to see wild polar bears with Frontiers North Tundra Buggy Adventures.

After you and your students have identified ways to reduce your carbon footprint, take it to the next level and participate in the Siemens We Can Change the World Challenge.  The Siemens We Can Change the World Challenge is the premier national environmental sustainability competition for grades K-12 students.

Through project-based learning, students learn about science and conservation while creating solutions that impact their planet. Through March 5, 2013, teams from across the country are challenged to create sustainable, reproducible environmental improvements in their local communities.
