This booklet is both a teacher's manual and a student's manual in a series of booklets that make up the core of a Physical Science course designed for the freshman year of college and used by teachers in the 27 colleges participating in the Thirteen College Curriculum Program. This program is a curriculum revision project in support of 13…

This is part of a series of 42 Calculus Based Physics (CBP) modules totaling about 1,000 pages. The modules include study guides, practice tests, and mastery tests for a full-year individualized course in calculus-based physics based on the Personalized System of Instruction (PSI). The units are not intended to be used without outside materials;…

An elementary formalism is developed for representing curved space-time which allows transparent qualitative explanation of general relativistic effects and is used to make a conceptual analysis of Einstein's principle of equivalence. A final section outlines a number of student activities. (Author/SK)

Explains that the result of collision experiments with a linear arrangement of several identical elastic balls cannot be predicted solely from the conservation laws and energy and momentum. Indicates that the system of balls must be capable of dispersion-free energy propagation. (Author/JN)

Describes a systematic investigation of the understanding of velocity by students in introductory physics courses. Data were obtained using the individual demonstration interview, similar to the clinical interview. Results are reported for success of different populations in comparing velocities for two simultaneous motions. Implications for…

Discusses the mechanism and the change of pH during the reaction. Notes that a dramatic rise in pH occurs when the reaction nears completion. Evaluates theories by other authors. (MVL)

Contains articles on digestive enzymes in grasshoppers; bird and badger observation; reactions between hydrochloric acid and sodium carbonate solutions; observing the migration of ions; pupil's heating skills (Bunsen burners); photolysis experimentation; capillary kinetics; experience with trireme; connection circuits; special relativity; a…

Described is the application of microcomputers to predict reaction rates based on theoretical atomic and molecular properties taught in undergraduate physical chemistry. Listed is the BASIC program which computes the partition functions for any specific bimolecular reactants. These functions are then used to calculate the pre-exponential factor of…

An activity in which students obtain a growth curve for algae, identify the exponential and linear growth phases, and calculate the parameters which characterize both phases is described. The procedure, a list of required materials, experimental conditions, analytical technique, and a discussion of the interpretations of individual results are…

Compares three domains in kinesiology with regard to essential professional competencies: biophysical sciences focused on exercise and sport, behavioral/sociocultural sciences focused on sport, and pedagogical sciences focused on school physical education. The paper compares the relative emphases placed on technical and critical/reflective…

Describes a study of high school students' and chemistry teachers' understanding of the gas laws which focused on the application of scientific concepts in practical situations instead of mathematical calculations in theoretical situations. (Contains 13 references.) (WRM)

As part of a larger project aimed at exploring how students' conceptual growth results from interacting with the teacher and the assigned readings associated with a course, this study focused on how prospective elementary teachers conceptualized two concepts, evaporation and condensation in a Concepts in Earth Science Course. In the conceptual…

Presented is the second part of the K-12 unified science materials used in the public schools of Anne Arundel County, Maryland. Detailed descriptions are made of the roles of students and teachers, purposes of the bibliography, major concepts in unified science, processes of inquiry, a scheme and model for scientific literacy, and program…

Presents an experimental example illustrating the most common methods for the determination of kinetic parameters. Discusses the different theories and equations to be applied and the mechanism derived from the kinetic results. (CW)

Regrouping cars from incoming trains into blocks of cars for outgoing trains is accomplished in railroad "hump" classification yards. Discusses: hardware and software elements of such installations; physical models on which software is based; success in predicting/regulating car speeds; and results of recent research into factors…
