Outlines Marquette University's response to declining enrollments and financial restraints for its undergraduate biology curriculum, beginning with a description of the old program and its problems. Discusses redefinition of laboratory role, uncoupling and reducing number of laboratories required, teacher responsibility changes, centralized…

The following aspects of the radiochemistry program at San Jose State University in California are described: the undergraduate program in radiation chemistry, the new nuclear science facility, and academic programs in nuclear science for students not attending San Jose State University. (BT)

Discusses a student exercise which requires the optimizing of the charring and atomization temperatures by producing a plot of absorbance versus temperature for each temperature parameter. Notes that although the graphite furnace atomic absorption spectroscopy technique has widespread industrial use, there are no published, structured experiments…

Gives upper level chemistry students a better understanding of the application of lasers in the field of spectroscopy. Provides three experiments to demonstrate the thermal lens effect: determination of beam profile, cell position optimization, and pKa determination. (MVL)

Presents an overview of biochemical education in China, including a description of the overall Chinese educational system. Summarizes workshop sessions which dealt with teaching objectives, teaching methods, self-instruction, and the education of graduate students (including the use of "dry" laboratory exercises and research…

The laboratory curriculum of an introductory physical geology course which emphasizes a peer-learning approach is discussed. (Author/SA)

Provides a point of view that the organic lab is a good place for the student to use and learn problem solving skills while performing the cookbook experiments. Notes that an equilibrium between the theoretical and practical aspects of organic chemistry should be established. (MVL)

Reports on the session at the New England Association of Chemistry Teachers meeting on chemistry laboratories in March 1987. Speakers included Leonard K. Nash and Audrey Champagne on values and goals; Howard Ende on regulation; Stanley Smith and Jerry Bell on the uses of computers; and Miles Pickering on the human dimension. (CW)

Describes a molar volume-molar mass experiment for use in general chemistry laboratories. Gives background technical information, procedures for the titration of aqueous hydrogen peroxide with standard potassium permanganate and catalytic decomposition of hydrogen peroxide to produce oxygen, and a discussion of the results obtained in three…

The use of microcomputers in the undergraduate chemistry laboratory is presented. Examples are included which can be implemented in the PET 2001. (SA)

The spaces and structures used for undergraduate science often work against new teaching methods and fail to provide environments that attract the brightest students to science. The undergraduate science building often offers little to inspire the imaginations of young minds. The typical undergraduate science building also tends to work against…

Discusses responsibilities for providing safe experiments and for teaching about safety. Provides lists of references on chemical safety and regulated/potential carcinogens. Also discusses general laboratory safety procedures including waste disposal and recycling of solvents. (JM)

Presents a halogen substitution of an alkane using a compartmentalized Petri dish or Conway dish on an overhead projector. Provides methodology and several modifications for different reactions. Uses hexane, methyl orange, bromine, and silver nitrate. (MVL)

Explores the structural behavior of polyenic pi systems such as isomerization and conjugation. Uses the simultaneous spectrophotometric analysis of a beta-carotene and lycopene mixture. Presents an empirical method to determine the number of double bonds in the polyenic carotenoid. (MVL)

Discusses electron spin resonance, a form of magnetic resonance spectroscopy, used to study electronic structure of molecules with unpaired electrons. Studies benzosemiquinone radical anions which are long-lived and inexpensive. Uses a Project SERAPHIM computer program to perform a Huckel molecular orbital calculation. (MVL)
