Disney's Planet Challenge™ (DPC) is a FREE, highly-acclaimed, project-based, environmental competition for elementary and middle school students all across the United States. The program inspires students to be good stewards of the environment and empowers them to make a difference in their school, at home and in their local communities. All of these goals are achieved, while teaching kids about science, conservation and positive ways to impact the planet.
