Describes an undergraduate biochemical experiment involving the isolation and characterization of acid phosphatase from readily available materials. (Author/SL)

Discusses the development, goals, syllabus and evaluation of a four semester hour credit human-centered college biology course for nonscience majors. Brief annotations of sub units of the course are provided. In the course, the use of science-related periodical articles is encouraged. (CP)

Utilizes a pretest-posttest design to determine if participants (N=26) exhibit significant gains in organic, inorganic, and biological chemistry concepts as the result of a six-week summer program. Significant gains in these areas and in an understanding of the methods and procedures used in scientific explanation are found. (CP)

Discussed are how the thermal vibrations of a solid are described in terms of lattice waves, how these waves interact with other waves, or with themselves, and how one is led from such a description in terms of waves to the concept of a phonon. (Author/MA)

Formulae are proposed for the distinct cases of monatomic and diatomic gas volumes. Eight figures illustrate the article. (Author/MA)

Describes a rotating chair with sliding calibrated masses suitable for demonstrating and determining the conservation of angular momentums. (SL)

Explores hypothesized interrelationships between levels of moral valuing (Kohlberg) and three aspects of environment-related behavior: environmental knowledge, emotionality, and activity. Four standardized instruments were administered to 140 college students. Findings revealed that subjects were more emotionally involved with the environment than…

Compares the instructional objectives of teachers, supervisors and engineers in the field of statics, strength of materials and machine parts. (CP)

Describes a one-year interdisciplinary introductory science course presented at the University of Michigan, Dearborn, for nonscience majors. (SL)

Presents a new application of the WKB approximation to the hadronic atom elementary enough for undergraduate quantum mechanics students. (SL)

Presents physical analogs to provide visualization of rates of chemical reactions and dynamic chemical equilibrium. (SL)

Presents classroom and laboratory teaching and demonstration ideas, including a demonstration of optical rotation, automatic potentiometric titration, preparation of radioactive lead, and an organic lab practical in library resources. (SL)

Presents a method for producing a large image optical spectrum on an overhead projector. (SL)

The concept of community energy flow provides a basis for a field course. This paper describes the methodology used in a field course for estimating parameters and for monitoring physical environmental variables. The paper culminates in the construction of a model of energy flow through the community. (Author/MA)

Provides a rationale and methodology for measuring student attitudes and affective learning. (SL)
