"Earth2Class" (E2C)is a unique professional development program designed to improve the knowledge, teaching, and technology skills of middle and high school science educators. Each session features special presentations by Lamont-Doherty Earth Observatory research scientists and staff about their cutting-edge investigations about important geoscience questions. The E2C Team provides theme-related content information, curriculum activities, technology integration, and educational resources. Participants can adapt these samples to meet the concepts and skills needed for their classes. Teleconferencing has permitted teachers at remote locations to participate in these stimulating and enriching experiences. E2C also provides a model for collaboration between research and educational institutions.
