Describes an activity using simple materials that gives students an opportunity to express their ideas about possible extraterrestrial life forms. (JR)

Activities designed to teach children about solar distance and size are presented. These include a classroom-sized model, an outdoor model, a read-aloud activity, and follow-up activities. Available resource materials in print and on film are listed. (CW)

Describes a secondary project in which students must organize an expedition to settle the people of the Earth on a new planet. (MLH)

Three activities--"Earth's Orbit and the Four Seasons,""Observing Rabbits," and "Solutes, Solvents, and Solutions"--are described. Included in each are background information, a list of materials, key questions, teacher preparation, teacher introduction, procedure, and follow-up activities. (CW)

Fourteen astronomy activities are presented including classroom procedures and questions. Topics include different investigations of the moon, planets, stars, sunsets, light pollution, and rainbows and halos. Additional information on measurements used for observations in astronomy, and rainbow characteristics is included. (CW)

Presents an activity whereby students describe the path of Mars through a background starfield. Includes purpose, materials, pre-lab, and procedure. Also provides guidelines for making a dial-a-planet wheel. (MA)

Presents three activities that allow students to practice some of the techniques used by lunar researchers, and to become more familiar with lunar features through scrutiny of lunar photography. Topics include dimensions of a crater, different surface ages, and types of rilles. (Author/MA)

Presents activities designed to help children experimentally determine what the dark areas of the moon consist of, and compares primary children's ideas about the moon with those of early scientists. (WRM)

Presents two exercises in astronomy: (1) the production of star trails and (2) the measurement of the distance between stars and their apparent movement in the sky. Includes directions, illustrations, and activity questions. (MA)

Describes a constructivist approach to teaching a second-grade science unit focusing on the moon, using student observations and data collection. Lays the foundation for the evolving development of conceptual understandings of earth, moon, and sun interrelationships in other grades throughout the school. (nine references) (JRH)

Presents activities in which students play the role of cadets performing missions for the fictitious SETI (Search for Extraterrestrial Intelligence) Academy. Guides students toward an understanding of evolutionary forces and how they are affected by the physical environment. (JRH)

Describes a lively investigation to interrelate biology, math, physics, and chemistry with our nations space program. Suggested for use with tenth grade biology students when dealing with topics relevant to animal stress reactions. References are cited. (EB)

Describes a project making a model of the celestial sphere that will show how the ancients imagined the universe. (PR)

Proposes an activity whereby science students develop critical thinking skills. Students are to debate the belief that the earth is flat. Guidelines are provided. (MA)
