Suggests using the planetarium as an educational resource for all ages. Discusses various planetarium teaching techniques and planetarium programs (with objectives) at Ball State University. They include programs for school children, college students, and the general public. (DH)

Discusses properties of epicycloids. (The easiest way to picture them is to think of a piece of radioactive bubble gum attached to a wheel which is rolling around the outside of a larger wheel.) Includes a computer program (TRS-80 color computer) that will graph any epicycloid with integer values for the radii. (JN)

Presented is the index to The Physics Teacher journal for January-December 1976 (Volume 13). Index is by subject and by author. (SL)

This issue of Exploratorium Magazine focuses on the topic of motion. Contents include: (1) "First Word" (Zach Tobias); (2) "Cosmic Collisions" (Robert Irion); (3) "The Mobile Cell" (Karen E. Kalumuck); (4) "The Paths of Paths" (Steven Vogel); (5) "Fragments" (Pearl Tesler); (6) "Moving Pictures" (Amy Snyder); (7) "Plants on the Go" (Katharine…

This textbook is designed to aid teachers who are using the "Fourteen Weeks Course." The problems contained in all the books are solved. The book contains answers in natural philosophy, chemistry, descriptive astronomy, experiments in chemistry, human physiology, physics, and astronomy.

Presents two examples of astronomical problems suitable for use in teaching of Newton's and Kepler's laws of motion in a logical fashion. Indicates that the gratuitous presentation of physical principles may lead to removal of student interests and sense of achievement and satisfaction in the study of physics. (CC)

Describes the development of a multi-topic, individually-paced, upper-level seminar on the solar system carried out primarily for nonscience majors in the spring and fall semesters of 1972. Also discusses the course objectives and related evaluation instruments. (CC)

A planetarium design is based on (1) planetarium guidelines from a survey of educational research and literature and (2) compilations of comparative information about different planetarium functions and their integrative design possibilities. (DF)

Recent models of stellar nucleosynthesis can be effectively used to provide a unifying theme for the teaching of nuclear phenomena to chemistry students. (Author/DF)

Reviews ideas and evidence bearing on the origin of life. Shows that evidence to support modifications of Oparin's theories of the origin of biological constituents from inorganic materials is accumulating, and that the necessary components are readily obtained from the simple gases found in the universe.

The objective of the research was to develop a self-instructional course through educational technology modules and to evaluate it, using freshmen non-science majors. (Author/CP)

Describes the structure of the observatory built in India in 1710 and shows the relationship of the scientific and geometric principles involved. (AL)
