Studies the elastic linear collision of three bodies of equal mass. One of the bodies is incident on the other two which are at rest and in contact with each other. (GA)

This experiment is suitable for illustrating synthesis-analysis and isopolyanion chemistry at the freshman level or at a more advanced level. (BB)

In this general chemistry experiment students calculate changes in free energy of formation of inorganic salts from the free energy of formation of ions. Then they test the conclusions of their calculations by mixing solutions of the ions. (BB)

Describes an undergraduate course, The Colonization of Space, which introduces nonscience majors at the University of North Florida to current topics in the exploration, industrialization, and colonization of space. References to the audiovisual resources and literature are also included. (HM)

Presents a laboratory experiment that was developed to acquaint physics students with field-effect transistor characteristics and circuits. Computer-drawn curves supplementing student laboratory exercises can be generated to provide more permanent, usable data than those taken from a curve tracer. (HM)

Presents brief notes on new ideas, equipment, techniques, or materials of interest to teachers of physics. An apparatus that demonstrates the uniform acceleration of gravity, and a simple way to demonstrate nuclear blocking patterns of crystal lattices are among new ideas presented. (HM)

Comparison of SAT math scores, high school grade point averages (GPAs), and final chemistry grades for both the 1972 and 1976 fall semester classes of the first-year chemistry course at the University of Virginia showed that SAT math scores were a much better predictor of final chemistry grades than were high school GPAs. (BB)

This is a college-level general chemistry experiment. (BB)

The findings of Piaget suggest that learning physics can help people achieve a series of four distinct but overlapping stages of intellectual growth as they search for patterns and relationships. (MLH)

Describes an interdisciplinary course on physics and history. The major goal of the course is to examine and compare history and physics in order to illuminate the implicit assumptions underlying the two disciplines. (MLH)

Suspensions of 20 different cultures were grown on appropriate media, then pipetted into sterile anhydrous silica gel. Silica gel cultures after incubation and refrigerated storage were tested for viability. Results showed little mutation, low replication, low contamination, minimal expenses, and survival up to two years. (CS)

Suggests unorthodox methods that may help to make studying more agreeable to students. Discussed are organizing complex cheat notes, use of chalkboard on pretending to give lectures on the subject to be mastered, developing an appreciation ("psyching out") for the professor's philosophy, and using flash cards for vocabulary mastery. (CS)

Describes how student responses to 26 bipolar adjectives describing laboratory studies are used at a New Zealand university to modify the content of laboratory experiments in physics. (MLH)

Describes a lecture teaching technique called lap-dissolve projection in which two slide projectors are operated alternately so that one visual image fades away while the next appears on the same screen area. (MLH)

Discusses the use of lap-dissolve projection to give students pre-laboratory instruction on an upcoming experiment. In this technique, two slide projectors are operated alternately so that one visual image fades away while the next appears on the same screen area. (MLH)
