A simple, rapid, and safe method has been developed for disrupting bacterial cells for protein studies. The method involved stepwise treatment of cells with acetone and with sodium dodecyl sulfate solution to allow extraction of cellular proteins for analysis by polyacrylamide gel electrophoresis. Applications for instructional purposes are noted.…

Extensive and detailed overhead projections, a complete set of reduced overhead miniatures in booklet form for each student, and tape recordings are used in a lecture setting to capitalize on the learning preferences of both visual and auditory learners. The use of the strategy in introductory chemistry is described. (JN)

The expanded use of microcomputers, including word processing, to improve productivity of geological educators and students is discussed. Topic areas examined include: computer development and academic use; word processing with microcomputers; instructional uses and other applications; impacts on academia; and acquisition. (BC)

Describes a series of challenges related to areas other than the knowledge content of a course to achieve a similar goal. These challenges are designed to teach not only analytical skills but also such process skills as organization, record keeping, report writing, cooperation with fellow workers, and resolution of discrepancies. (JN)

An undergraduate research program in natural product synthesis was established at a small liberal arts college. Discusses program goals (including the total synthesis of maytansine), objectives, and accomplishments to date. Guidelines for establishing such programs are offered. (JN)

The benefits of undergraduate research programs for faculty members are described. Proposal strategies for new faculty, working in the undergraduate setting, and role of the senior faculty are the other major areas considered. (JN)

Examines programmatic effects of undergraduate chemistry research programs, focusing on internal research funding at Pomona College. The two-phase funding plan is described, accompanied by commentary on the reasoning and philosophy which lie behind these procedures. (JN)

Describes: Apple stereochemistry program; CNDO/2-INDO mini-computer calculations; direct linear plot procedure for enzyme kinetics calculations; construction of nonlinear Scatchard plots; simulation of mass spectral envelopes of polyisotopic elements; graphics with a dot-matrix printer; MINC computer in the physical chemistry laboratory; hallway…

Federal parks and monuments are numerous, widespread, and offer unique opportunities for funded research and employment for science undergraduates. Elements essential to quality undergraduate research, contacts, research needs, and funding are discussed, along with description of a successful undergraduate field research program in Missouri. (DH)

Investigated effects of teaching an explicit approach to problem solving on the mathematical chemistry achievement of preparatory college students (with a control group being taught dimensional analysis as its problem-solving strategy). No difference in cumulative achievement between the groups was found. Interpretations of the results obtained…

Describes a microcomputer-based, multichannel digital data acquisition system for acoustic signals. Hardware and software considerations are included. (JN)

Describes industrial acetaldehyde synthesis/uses, explaining why acetaldehyde usage is declining in industry. Includes a discussion of the reaction chemistry, equations, and molecular structure diagrams. (JM)

Provides an annotated list of 36 items for teaching the use of the chemical literature including price, address of suppliers, description and/or published evaluations whenever available. Materials include slides, audiocassettes, films, filmstrips, graphs, photographs, and videocassettes. (JM)

Provides directions for setup and performance of two demonstrations. The first demonstrates the principles of Raoult's Law; using a simple apparatus designed to measure vapor pressure. The second illustrates the energy available from alcohol combustion (includes safety precautions) using an alcohol-fueled missile. (JM)

Describes a comprehensive nuclear magnetic resonance (NMR) experiment designed to introduce undergraduate organic chemistry students to measurement/interpretation of NMR parameters. Students investigate chemical shift analysis, spin-spin coupling, peak integrations, effect of deuterium oxide extraction, and comparisons with literature spectra;…
