Describes a general chemistry course taught by the Keller Plan, or personalized system of instruction, at a university with a large minority enrollment. Evaluation shows that students feel that they are learning more and getting higher grades. (MLH)

Describes three experiments illustrating some technological applications of liquid crystal substances, which are currently used to display numbers and letters by scattering of ambient light. (MLH)

Discusses the planning and organization of an instrumental analysis course for chemistry majors designed to acquaint the students with an appreciation of the variety of ways available for a given analysis. Describes grading procedures and the use of taped lectures. (MLH)

Describes an inexpensive apparatus that can be constructed from ordinary laboratory materials that will convert precoated thin layer chromatography plates into channeled plates. (MLH)

Discusses a laboratory experiment in which uranium is isolated by the reduction of uranyl acetate. (MLH)

Supplies the names of British publications that contain chemistry questions, most of them at the high school level. (MLH)

Two groups of tenth-grade Israeli students were instructed in Chemistry using either films or laboratory experiments. Results of this study show that the films were an effective substitute for students' individual laboratory work. (MLH)

Describes the synthesis of a sweetening compound that requires seven laboratory periods of three-hours duration. (MLH)

Describes a technique by which room temperature phosphorescence of simple organic molecules can be demonstrated in the lecture hall or laboratory. (MLH)

Presents a kinetic study that utilizes a method for varying the concentrations of the possible Ce(IV) species and computing the concentration distribution of the sulfato and hydroxo species of Ce(IV). (MLH)

Presents an inorganic oxidation-reduction kinetics experiment, and describes a low cost (less than $50) modification of the Bausch and Lomb Spectronic 20 Colorimeter which will provide a linear output in absorbance. (MLH)

Describes an entry into the synthesis of the cyclopropenone series that is designed for the undergraduate organic chemistry laboratory. (MLH)

Presents a summary of the state of the field in instrumentation as it existed in 1940-1941 as described in articles written at that time by R. H. Muller. (SLH)

Presents an experimental approach to teaching molecular orbital models. Suggests utilizing photoelectron spectroscopy and molecular orbital theory as complementary approaches to teaching the qualitative concepts basic to molecular orbital theory. (SLH)

Presents a brief history of the events leading to the characterization of the compound thought to be ditellurium decafluoride. Notes reasons why this was inaccurate and suggests methods by which the compound might be prepared. (SLH)
