When you need supplemental materials for NASA-related lessons and activities, the Central Operation of Resources for Educators may be your answer. CORE serves as the worldwide distribution center for NASA-produced multimedia materials. You may purchase the materials for a minimal charge. Resources available from CORE include activity kits, CD-ROMs and DVDs, posters, and space memorabilia. The kits and memorabilia may be especially useful for student demonstrations in DIY Podcast video productions.
