NOAA's Office of Education (OED) grants for one- to five-year environmental literacy projects promoting changes in K-12 education to expand the amount of Earth System Science taught in the classroom and improve student learning and application of that subject. NOAA's ELG Program is the nation's longest standing and most comprehensive grants program focused on environmental literacy. The program provides funding for formal and informal STEM education projects on regional to national scales for both public and K-12 audiences.
