This resource guide is a supplement, covering the years 1973-1976, to a compendium of astronomy educational materials published in 1970. The majority of the listings are books published in English that would be of use in astronomy education. Levels are classified as follows: general public, amateur astronomers, university science students,…

Provides a chronicle of the work of Miss Leavitt in the field of variable stars during the early part of the 20th century. (CP)

Gives a short biography of James E. Keeler, and describes some of his outstanding discoveries, and his pioneering work in observational research where he applied physical methods to the analysis of planets, stars and nebulae. (GA)

Describes some alternate theories to the big bang theory, such as Ellis' static universe with its two centers, and Dirac's large number hypothesis and his unified field theory. (GA)

Presents a bibliography of books for upper elementary students. The books deal with aspects of space in the seventies, changing concepts of the universe, and how today's science and technology are trying to answer the questions these concepts raise. (Author/GA)

Investigates the effect of three models of teaching college astronomy on knowledge acquisition, based on the principles of kinetic structure analysis and the psychological concept of mass versus distributed practice. Results indicate that distributed integration is better than nondistributed integration in teaching certain fields in astronomy. (HM)

Discusses the process of stellar death and the correlation between the size of a star in solar masses and its way of death. The amount of mass loss that occurs during the life and death of a star is also discussed. (HM)

Describes an electronic circuit which can be used to demonstrate the stellar magnitude scale. Six rectangular light-emitting diodes with independently adjustable duty cycles represent stars of magnitudes 1 through 6. Experimentally verifies the logarithmic response of the eye. (Author/GA)

Although helium is the second most abundant element in the universe, very little is found in the earth. This article discusses the geochemical cycle of helium and attempts to account for the scarcity of helium. (MA)

Discusses and summarizes papers on lunar geology and volcanism presented at the Lunar and Planetary Science Conference. (MR)

Discusses research to learn more about the interiors of the moon and planets. (MR)

Reviews current theories concerning the physics of the sun. (SL)

Reviews the current state of knowledge obtained by means of observations using the increasingly powerful or proficient instruments of astrophysics, radio astronomy, and space astronomy by satellite. In conclusion, he refers to certain mathematical entities introduced into the theory of the origins and evolution of the cosmos. (Author/MA)

Provides background information about the planet Pluto. Includes the history of Pluto and discusses some of the common misconceptions about the planets. Addresses some of the recent discoveries about Pluto and contains a resource list of books, articles, and a videotape. (TW)

Provides information of various astronomy software. Each entry includes title, source, type of microcomputer on which the program will run and very brief descriptions. (JN)
