The three units of study presented are designed to promote space-related learning opportunities for gifted students and were prepared by recipients of the Scobee curriculum awards. In "Galactic Colonization for Our Future Astronauts" (Jacqueline Shimonauff), elementary-level students simulate a space experience in which a ship carries materials into high earth orbit to be used in building a space station-travel ship. The travel ship carries people to a planet in another galaxy, and on the planet, three colonies are developed. The students learn about spaceship design and staffing and establishment of various systems (government, economics, education, transportation, and communication) in the new colonies. "Flying High: A Space Science Curriculum Unit" (Paul Robinson) simulates for secondary students the experience of selecting, designing, building, and launching an experiment on the space shuttle. "Search for Truth" (Jane Schaffer), for middle grades and secondary students, stresses the value and meaning of searching and exploring self, others, and the world through literature. Each unit of study includes a bibliography. (JDD)
