The author sees the physical sciences as processes of inquiry and proceeds to analyze and criticize CHEM Study, CBA, and PSSC physics in terms of their views of inquiry and of the sciences. A discussion of some desirable features for a high school program in physical science is included. Bibliography. (LC)

The temperature at which the onset of coordinated segmental motion begins is called the glass-rubber transition temperature (Tg). Natural rubber at room temperature is a good example of a material above its Tg. Describes an experiment examining the response of a typical polymer to temperature variations above and below Tg. (Author/JN)

Describes an eight-module, high school chemistry curriculum (including outline of course content) which encourages students to envision chemistry as a science based on general, related concepts rather than on a discipline composed of segmented, isolated topics. Module 1 objectives, assignments, laboratory experiences, and test are available from…

Suggests that it is not necessary to present in chronological order all the experiments leading to development of the Planck formula. Presents a simple, alternative way of introducing this important formula. Although the treatment is not new, it is found in very few textbooks. (JN)

Overvoltage, also called overpotential, activation overpotential, and kinetic polarization, is the voltage in excess of the reversible value which is required to cause a cell reaction to proceed at an appreciable rate. Provided is a simple and dramatic demonstration of overvoltage. (JN)

Cerenkov counting is a useful technique for assaying medium/high energy beta emitters in aqueous solutions. Advantages of the technique include: (1) simple sample preparation; (2) being able to handle large volume of aqueous solution for counting; and (3) absence of chemical quenching. Cerenkov counting is also less expensive than other methods.…

Discusses how chemistry departments at three campuses of the University of California (Berkeley, Davis, and Irvine) and at the University of Michigan have fared during the years of lean budgets. Indicates that these universities are helped by healthy research funding, academic strengths, service roles, and selective budget cuts. (JN)

Shows how a statistical approach can help students accept postulates of quantum mechanics. The approach, which also makes students aware of the philosophical/humanistic implications of quantum mechanics, involves the following sequence: (1) important experiments in quantum mechanics; (2) conventional statistical interpretation; (3) mathematical…
