Lists numerous career opportunities in the area of environmental physics and programs leading to degrees in the field. (CP)

The administration of a Personalized System of Instruction (PSI) for junior-senior level courses in mechanics, electricity and magneturn, atomic physics, mathematical physics, physics and computers, astrophysics, and relativity is described. (CP)

Provides a theoretical model of the deoxyribonucleic acid (DNA) helix-to-coil transition in order to obtain magnitude information about the strength of the molecular bonds involved. (Author/CP)

Reports on the increased enthusiasm of college students toward physics following the development of student-activated corridor display units. Includes a listing of displays and comments on student reactions. (CP)

Presents the first of a four part series of interviews of physics teachers who have won the American Association of Physics Teachers (AAPT) Innovative Teaching Award. This first review emphasizes the type of course taught and the teacher's role. (SL)

Describes a method being developed for teaching mathematical physics at the college level without the use of calculus. (SL)

The author relates his success as a technical consultant for numerous firms. Outlined are basic procedures for getting started in consulting and tips on structuring the consulting aspect of a science career. Included are illustrations of some of the apparati produced as a result of consultant assistance. (MA)

In this exercise, students examine Aristotle's weight hypothesis by testing variously shaped marble chips. These chips are weighed and dropped down a water tube. Average fall times and weights are recorded and graphed. Students are asked to apply this information to rock and soil deposition by streams. (MA)

Examination of the content knowledge of six experienced secondary school physics and biology teachers through observation of instructional planning indicated that the influence of the teachers' subject matter knowledge was evident in their modifications of textbook subject matter content and through their use of explanatory representations.…

Refutes the Doppler effect as the explanation of large red shifts in the spectra of distant galaxies and explains the relativistic effects in which the light sources approach the observer obliquely. Provides several diagrams and graphs. (YP)

Describes two demonstrations for use in college chemistry classes. Includes "Spectroscopy in Large Lecture Halls" and "The Endothermic Dissolution of Ammonium Nitrate." Gives materials lists and procedures as well as a discussion of the results. (CW)

Reports on an analysis of secondary school physics teaching with respect to three aspects of curriculum. Indicates that limited but significant relationships exist among intentions, translations, and achievement in the teaching of physics in Canadian secondary schools. (TW)

Described is a series of five related microcomputer-based laboratory analysis programs that are used by students in a college calculus-based physics course. With minor modifications these programs, which are written in BASIC, could be used in most beginning undergraduate laboratory science courses. (RH)

Discusses a series of experiments performed by Thomas Hope in 1805 which show the temperature at which water has its maximum density. Early data cast into a modern form as well as guidelines and recent data collected from the author provide background for duplicating Hope's experiments in the classroom. (JN)

Describes university courses of study in physics in England, Wales, and Northern Ireland. Provides areas of concentration, special notes, and contact point for further information. (JM)
