TERC proposes to create an Earth Systems Climate EarthLabs module comprised of nine sequential, inquiry-based lab activities that introduce students to Earth system science and climate change which are based on the Exploring the Connections activities of the Earth as a System chapter of the GLOBE Teachers Guide. The lab experiences will feature a combination of fieldwork and classroom activities integrating NASA visualizations and data, and will demonstrate the rigor and depth of true lab courses. The module will be freely accessible on the web, will integrate teacher professional development support, and will serve as a lab component for capstone high-school Earth science courses. It will facilitate the emergence of lab-based Earth science courses certified for college admissions and increase the number of students who study global climate change.
