Presents a unit of study on the moon and the teaching method used with a sixth grade class. Students were involved in many aspects of scientific investigations; individual differences were met in a variety of ways. (BR)

Provided are two tables which contain the latest orbital and physical characteristics of the planets and their main satellites. These tables are part of a series of information materials available from the Astronomical Society of the Pacific, 1290 24th Avenue, San Francisco, CA 94122. (JN)

Highlights the career and accomplishments of Philip Morrison, one of the most thoughtful advocates of arms control, valued for his scientific contributions to the Manhattan Project, theoretical physics, astrophysics, and the public understanding of science. (Author/JN)

Techniques for a successful nighttime field trip to observe celestial wonders are presented. The author describes such a trip, taken with gifted fifth graders. (KC)

Described is the observation of the moon with binoculars. Descriptions of the thin crescent moon, three-day-old moon, five-day-old moon, first quarter moon, 10-day-old moon and the full moon are presented and characteristics of each phase are included. (DS)

Provides information on the calculation of the redshift to blueshift ratio introduced by the transverse Doppler effect at relativistic speeds. Indicates that this shift should be mentioned in discussions of whether quasars are "local" rather than "cosmological" objects. (GS)

Presents a method suitable for intermediate level astronomy courses for the calculations of solar eclipses which avoids spherical trigonometry. (Author/CS)

An annotated bibliography of astronomy activities is provided. Appropriate level for suggested activities is indicated. (MK)

The abundance and distribution of the elements on the earth can, in part, be explained in terms of chemical properties such as reduction potentials, solubilities, ionic size, densities, melting points, and pH. The relative abundance of the elements, their distribution, and their concentration, particularly on the earth, are discussed. (Author/BB)

An argument is made for the inclusion of astronomy in the elementary curriculum. Suggestions are made for incorporating astronomy into the curriculum and for training teachers. (MP)

Presents the most important features of observational astronomy, including the motions of the sun and the moon and the methods by which eclipses can be predicted. (MLH)
