Experiments designed to help undergraduate students gain experience operating instruments and interpreting gas chromatography and mass spectrometry data are presented. Experimental reagents, procedures, analysis, and probable results are discussed. (CW)

Discussed is an extension of the conventional method for studying the organometallic chemistry of transition metals that may be useful to show how the various existing types of low-valence complexes can be constructed. This method allows students to design new types of complexes that may still be nonexistent. (CW)

Shows that two theories of stereochemistry were very different theories, grounded in different assumptions and were intended to explain different phenomena. Presents the original theories and later developments which caused a blending of the theories. (Author/MVL)

Describes a photochemistry experiment designed to introduce photochemical techniques and experience free radical chemistry. Selects Nuclear Magnetic Resonance spectroscopy for the analysis. This activity is suggested for use in an upper level undergraduate organic course. (MVL)

Describes some reactions for the identification and application of cyanuric acid. Suggests students may find this applied chemistry interesting because of the use of cyanuric acid in swimming pools and diesel engines. Lists three tests for cyanate ion and two tests for cyanuric acid. (MVL)

Lists 67 published or marketed chemistry games organized under the following categories: (1) general knowledge; (2) elements and atomic structure; (3) nomenclature, formulas, and equation writing; (4) chemical reactions; (5) solutions and solubilities; (6) organic chemistry, and (8) miscellaneous subjects. Includes a brief description of each…

Presents a series of experiments that can be used to demonstrate how aspirin can be synthesized and characterized, how the hydrolysis of aspirin can be used as an introduction to kinetics, and how coordination chemistry (chelation) can be introduced by preparing and characterizing the copper complexes of aspirin and salicylic acid. (Contains over…

This report contains recommendations on chemical nomenclature, guidance on symbols, and terminology and units for physiochemical quantities. This report, intended to provide guidance to science teachers, consists of eleven sections: (1) general introduction; (2) introduction to symbols, terminology, and units for physiochemical quantities; (3)…

This booklet is a teacher's manual in a series of booklets that make up the core of a Physical Science course designed for the freshman year of college and used by teachers in the Thirteen College Curriculum Program. This program is a curriculum revision project in support of 13 predominantly Negro colleges and reflects educational research in the…

Discusses the production and use of polymer materials as thermal insulators. Lists several materials that provide varying degrees of insulation. Describes the production of polymer foam and focuses on the major applications of polystyrene foam, polyurethane foam, and polyisocyanurate foam. (TW)

Identifies a technique using methylene blue and glucose to explain a genetically related enzyme shortage causing blue skin in humans. Offers a laser technique to study solubility of silver salts of chloride and chromate. Encourages the use of models and class participation in the study of chirality and enantiomers. (ML)

Describes several experiments that explore the methodology available to the forensic serologist for typing a human bloodstain in the ABH grouping system. Presents ABO blood group of wet blood, Lattes Crust test procedure, and the absorption-elution procedure. Uses outdated blood; equipment requirements are minimal. (ML)

Outlines a multistep project involving oxidation of cholesterol, isomerization of an enone, and reduction of delta-4-cholesten-3-one. Featured is the last stage in which the ring junction is set stereospecifically. Recommends two laboratory periods to complete the reaction. (ML)

Describes a physical organic experiment in thermodynamics and kinetics for undergraduate courses in organic chemistry, biochemistry, or physical chemistry. Details background information, solution preparations, equipment and methods, and the suggested experiments such as determination of general-base-catalytic coefficients and the Bronsted…

Describes two introductory exercises designed to teach the fundamental ideas and methods of crystallography, and to convey some important features of inorganic and organic crystal structures to students in an advanced laboratory course. Exercises include "The Crystal Structure of NiO" and "The Crystal Structure of Beta-Fumaric Acid." (CW)
