Presents a short history relating how the chemical elements promethium (61), francium (87), and astatine (85) were formerly named illinium, virginium, and alabamine, respectively. (MLH)

Three questions and answers involving chemistry are presented. Question one involves elimination of reptiles from the earth; the second considers chemical effects on taste acuity; the third relates to muzzle velocity of a projectile fired from a gun and temperatures inside the cartridge. (MLH)

Describes a functional management system which individualizes instruction in undergraduate chemistry courses. CHEM TIPS (Chemistry Teaching Information Processing System) is designed to monitor each student's progress, identify specific weaknesses and strengths in his understanding of the course material, prescribe individual study assignments,…

Describes a study which compared the exam scores of students who worked in groups to those of students who worked as individuals in an undergraduate organic laboratory course. Results showed that the group approach produced significantly higher exam scores for low achievers. (MLH)

Describes the philosophy and content of an industrial chemistry course offered to seniors and graduate students. The course does not use a text; the chemistry is presented on projected transparencies which are also reproduced on paper and given to the students. Outside readings are predominately made in the "Encyclopedia of Chemical Technology."…

Describes the purpose, content, and relevancy of courses dealing with natural and artificial aquatic environments, including surface water and ground water systems as well as water and waste treatment processes. Describes existing programs which are offered at the graduate level in this subject area. (MLH)

Describes an undergraduate organic laboratory experiment involving the separation of an unknown solid organic acid and an unknown solid organic base. The experiment is designed to present the student with an unexpected difficulty, namely, the formation of a separable viscous liquid, to see how the student handles this difficulty. (MLH)

Presents four rebuttals to a suggestion that oxidation and reduction be defined in terms of increasing and decreasing oxidation numbers rather than as a gain or loss of electrons. (MLH)

Describes an inservice education system for secondary chemistry teachers called the Del Mod System. The activities in the system were based on recommendations gathered from secondary chemistry teachers during a two-year visitation program and included laboratory activities, a study of new developments in curriculum and methodology, and assessment…

Describes a series of experiments which illustrate the analytical capabilities of fluorescence, and outlines two straightforward analyses involving real analyses. These experiments are suitable for an undergraduate instrumental analysis course and require approximately six to seven hours of laboratory time. (MLH)
