Discussed are the construction and uses of a version of a photoelectric colorimeter by students. Included are materials needed and four experiments which use the equipment. Sample results are shown. (CW)

Described is a method that can be used to obtain molecular or atomic term symbols. Several examples accompany an explanation of the method. (CW)

This paper reports on the success of a laboratory teaching technique for teaching undergraduate chemistry. Discussed are the premises of the approach, and the use of the computer, the explorations, and the seminar which are included in the course. (CW)

Described is a spectrometer that can be used simultaneously by seven students to observe a single spectrum emitted by an element or compound in a single light tube against a calibrated screen. Included is a list of materials, directions for assembly, and procedures for use. (CW)

Presents a review of articles appealing to forensic practitioners. Topics include: drugs and poisons, forensic biochemistry, and trace evidence. Lists noteworthy books published on forensic science topics since 1986. (MVL)

Describes two easily applied mathematical theorems, Budan's rule and Rolle's theorem, that in addition to Descartes's rule of signs and intermediate-value theorem, are useful in chemical equilibrium. Provides examples that illustrate the use of all four theorems. Discusses limitations of the polynomial equation representation of chemical…

Discusses problem-solving strategies and the successful strategy used to solve stoichiometric problems in general college chemistry courses. Reports that rereading problems, recalling a related concept, and reasoning deductively/inductively are the most heavily used strategies among 13 categories. (YP)

Explains the use of constructing and analyzing analogies as a way to enhance student understanding and recollection of scientific concepts. Offers suggestions for topics including energy activation, phases of matter, electron transitions, equilibrium, covalent bonds, wave and particle duality, reaction types, ideal versus real gases, and oxidation…

Explains a summer research program which is a part of a required junior and senior independent study program. Provides information on selection of applicants, activities, outcomes, and a list of names and student projects. (RT)

Described are some computer software that can be used in chemistry classrooms: (1) "Polymer Tacticity in Simulated NMR Spectra"; (2) "Teaching Magnetic Resonance Imaging Using Computer Animation"; (3) "Emergency Response Database"; (4) "An X-ray Diffraction Pattern Simulator"; and (5) "Multiple-Choice…

Describes an inexpensive chemistry outreach program offered by graduate students to high school students. Lectures, color slides, demonstrations, and discussions were used. (YP)

Presented are four experiments for use in two wet analysis courses. These include comparisons and enzyme analysis. In each case, the theory behind each experiment is discussed. (CW)

Presented are three demonstrations: "The Construction and Use of Commercial Voltaic Cell Displays in Freshman Chemistry"; Dramatizing Isotopes: Deuterated Ice Cubes Sink"; and "A Simple Apparatus to Demonstrate Differing Gas Diffusion Rates (Graham's Law)." Materials, procedures, and safety considerations are discussed. (CW)

Reports on a survey of biology and chemistry instructors at 50 North Carolina community colleges to determine the types of courses taught, the diversity of students in the classroom, instructors' academic preparation and satisfaction with it, and perceptions of the value of secondary teaching for their current position. (DMM)

Described are chemistry and physics courses at several colleges as applications of the New Liberal Arts program for nonscience majors. The major themes of the program and several examples of this approach are discussed. (CW)
