Describes an exercise for obtaining the diameter of Venus by timing its occultation by the Moon, for a liberal arts astronomy course. (SL)

Describes a program which can be written to represent stellar motion in the galactic plane. (CP)

Describes a procedure that allows undergraduate students to determine the approximate age of the universe using their own data. The experiment requires a relatively small telescope with a modest spectrograph. Includes sample data and calculations. (Contains 11 references.) (Author/WRM)

Details the assembly and operation of two interactive computer-student dialogs developed for use primarily with elementary and secondary teachers. The dialogs use graphic facilities for teaching about the sky as seen from the earth and about the phases of the moon. (Author/CP)

Two methods are described for the quantitative description of the motion of the sun as observed from Mercury. A listing of a computer subroutine is included. The combination of slow rotation and high eccentricity of Mercury's orbit makes this problem an interesting one. (BB)

Exercises for introductory to intermediate level college students are proposed. Observations of pulsars can be used to illustrate the phenomena of dispersion and Faraday rotation of radio waves, and to illustrate the differential rotation of the galaxy. (BB)

Describes a simple method to measure the size of the Earth to an accuracy of order of magnitude 10 percent. The procedure involves finding the time interval between two sunsets, a sunset observed at sea level while lying down, and a sunset viewed at eye height after standing up. (GA)

Discusses the use of a horoscope-casting laboratory exercise in the astronomy course. Indicates that students can fulfill three objectives: (1) summarize the planetary motions in the geometric universe, (2) be familiar with sidereal and solar time, and (3) be acquainted with the uses ephemerides. (CC)

Describes an exercise developed by the author to help college students to become familiar with the technique of photoelectric photometry of variable stars and permits each student to work with data he or she has personally obtained. (HM)

Describes three dialog programs which have been used in introductory astronomy classes. The magnitude system, Kepler's third law, and the scientific method are the program topics. (CP)
