This resource for teachers of elementary age students provides a foundation for building a life-long interest in the U.S. space program. It begins with a basic understanding of man's attempt to conquer the air, then moves on to how we expanded into near-Earth space for our benefit. Students learn, through hands-on experiences, from projects performed within the atmosphere and others simulated in space. Major sections include: (1) Aeronautics, (2) Our Galaxy, (3) Propulsion Systems, and (4) Living in Space. The appendixes include a list of aerospace objectives, K-12; descriptions of spin-off technologies; a list of educational programs offered at the Kennedy Space Center (Florida); and photographs. (PR)
