Provides abstracts and materials requirements for 20 chromatography projects. Experiments range in complexity; some require synthesis steps, apparatus construction, or special preparation techniques. (MLH)

Describes an experiment, for the general chemistry laboratory, intended to introduce the student to infrared spectroscopy. After being introduced to the theory of molecular vibrations on an elementary level, each student receives a list of 5-7 nickel (II) ammines to be prepared, analyzed and characterized by infrared spectoscopy. (MLH)

Item analysis of a mathematics preknowledge test given to physics students revealed that significant differences existed on certain items between groups of students who had followed different mathematics syllabuses. (MLH)

Presents the rationale, general aims, course sequence, and course descriptions for a health studies program. This program requires from six to eight units for a major in this area. (GS)

Examines the employment problems of Ph.D. physicists in the traditional career areas of higher educatiion, industry, and government. Proposed solutions to the problem include not increasing physics graduate enrollment, annual manpower reports, student awareness of careers in non-traditional fields, and career mobility among older physicists. (GS)

Describes several programs of the American Association for the Advancement of Science (AAAS) Office of Science Education (OSE), including short courses offered in the natural and social sciences, mathematics, and engineering to college teachers. Discusses several OSE publications. (MLH)

States that it would be inappropriate to give in to student demands that they be taught according to their own standards, needs, and perceptions. The young must be introduced to intellectual discipline before they can appreciate its power. Outlines a curriculum design that would accomplish this goal. (GS)

Describes an experiment wherein the student can demonstrate the existence of all the thiocyanato chromium complexes, estimate the stepwise formation constants, demonstrate the robustness of chromium III complexes, and show the principles of paper electrophoresis. (GS)

Describes an experiment that will acquaint the student with the ion-exchange model, yield data which fit nicely to a computer type analysis, introduce the preparation of electrodes, provide a unique experience with elevated temperatures and ionic solvents, and provide experience in electrometric measurements. (GS)

Describes an experiment that illustrates the use of the preparative ultracentrifuge in isolating and purifying bacterial ribosomes, determines the sedimentation coefficients of the ribonucleoprotein particles, and demonstrates the subunit structure of the 70-S ribosome and the role of the magnesium ion in the association of subunits. (Author/GS)

Describes a laboratory experiment designed to merge the concepts and techniques of the analytical-organic-physical subdivisions and introduce the student to a decision-making situation. Presents a discussion of the use of the experiment in attaining these goals and provides typical data obtained by students. (GS)

Reports a modification of a simple method previously described for determining enthalpies of sublimation and comments on some of the method's inherent limitations. (Author/GS)

Describes a laboratory pretest giving samples of laboratory competencies, such as observing, interpreting, and calculating. Information from the test is related to student background and to overall success in the course. A test copy and tabulated data are included. (EB)

Describes a positive approach toward open-admissions policy taken by a new department in Interdisciplinary Science. The program is built on the strengths of its students and focuses on scientific problems of current importance that can be used to sharpen the student's analytical abilities and develop basic skills and concepts.
