The Expanding Children’s Interest through Experiential Learning (EXCITE) Project will target K-8th students in expanded learning programs to increase ongoing NASA STEM informal education opportunities for organizations that serve primarily underrepresented and underserved student populations. The AERO Institute will leverage existing collaborations to build capacity of participating organizations in NASA inspired STEM activities. Major partners include Navajo Nation in Arizona, the Beyond the Bell branch of the Los Angeles Unified School District, and the Region 8 of the California After School Program housed in the Ventura County of Education. In addition, the EXCITE Learning Project plans to work with libraries to broaden the scope and impact of NASA’s Education materials and opportunities within underrepresented and underserved local communities. AERO Education specialists will train educators and librarians using the Train-the-Trainer approach. The training sessions will be filmed and made available online via the AERO website and its network on YouTube so that educators and librarians can refresh their understanding as needed.
