Teachers from the United States and several other countries have access to the film library system of the National Aeronautics and Space Administration (NASA). This catalog contains the titles and abstracts for over 150 films that are available from NASA on topics regarding space flight, meteorology, astronomy, NASA programs, satellites, research, safety, technology, and earth sciences. Ordering and usage information are also included. A lesson guide is provided in the appendix to accompany 37 of these films. Each guide lists objectives, important vocabulary, preparatory activities, follow up activities, evaluation ideas, related information sources, and ideas for presenting the lesson. (CW)
