Registration is open for second phase of the Lexus Eco Challenge, which runs October 14 through November 11 for grades 6-12. In each phase, a teacher advisor selects a team of 5-10 students, and the team chooses one of the Air & Climate challenges to work on, and then the team implements an action plan and reports results via Powerpoint. Teams can win prizes and a chance to participate in the final challenge (November 18 – January 17).
