This teacher's guide describes seven audiovisual programs developed around the planet Mars. While these programs were developed primarily for use in secondary school science classes, several are appropriate for language arts, drama, art, and photography. Each program starts with the showing of a film or video-tape developed by the National Aeronautics and Space Administration (NASA). Included with each program are the following: program description, lesson purpose and alternatives, objectives, glossary of terms and concepts, suggestions for the presentation of the lesson, follow-up activities, and related sources of information. Topics discussed in these lessons include: the topography and geography of Mars; extraterrestrial life; space probes; and the evolution of Mars. (BT)
