Develops a lab experiment for introductory instrumental analysis that requires interference studies and optimizing of conditions. Notes the analysis of the aspirin is by visible spectrophotometric assay. Gives experimental details and discussion. (MVL)

Classroom demonstrations of selected mechanical properties of polymers are described that can be used to make quantitative measurements. Stiffness, strength, and extensibility are mechanical properties used to distinguish one polymer from another. (KR)

Describes a simple halogenation experiment that can be performed quickly in an open vessel at room temperature with visible light that is appropriate for the beginning weeks of an introductory organic chemistry course. (WRM)

Describes problems encountered in teaching a problem-centered undergraduate organic chemistry laboratory course. No text is used for this type of course; the students are encouraged to plan their own experimental routes. (MLH)

This unit is one of a group of units written to fit the Certificate of Sixth Year Studies (CSYS) chemistry course, but it could be used with most Sixth Form courses. It includes: (1) background information for teachers with notes on five topics (antifreeze, ethanol production, solvent prices, iron extraction, and paint solvents); (2) a student…

This collection of lessons deals with nutrition in health and medicine and specifically the digestive system and its functions. The primary objective of this collection of lessons is to provide information on what constitutes good nutrition. Among the problems treated in these lessons are heart disease, peptic ulcer, hepatitis, vitamin deficiency…

This booklet is a student 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 27 colleges participating in the Thirteen College curriculum Program. This program is a curriculum revision project in support of 13 predominantly Negro colleges and…

Research related students' orientation toward college and college majors to their attitudes toward computer-assisted instruction (CAI) and their performance in an organic chemistry course using CAI. Major findings were that: 1) students majoring in applied fields manifested more favorable attitudes toward both organic chemistry and CAI, than did…

Lecture and laboratory topics of a one-quarter, undergraduate course designed to introduce students to chemical principles and phenomena involving the automobile are described. (CP)

Contains contributed suggestions in the teaching of structure and bonding and reaction rates and equilibria in the Nuffield Advanced Chemistry Project. (CP)

Questions the continued misuse of Markovnikov's Rule in organic chemistry texts. Claims that the results of several studies that show the reaction to be more complex than it appears at first. Criticizes authors of new texts who have perpetrated the rule based on reading older texts. (TW)

Describes a process for producing terminal or internal alkynes from ketones. Recommends using the experiment to aid in understanding acid-base strength, enolate anion chemistry, reaction at carbon versus oxygen, use of polar aprotic solvents, and elimination and nucleophilic substitution reactions. (ML)

Describes three activities, substrate inhibition, product inhibition by fructose and glucose, and gel immobilization of invertase for use with undergraduate biochemistry classes. Discusses materials, methods, and results. Stresses the advantages of practical exercises in undergraduate classes. (CW)

Described is a teaching method for connecting relative acidity among various species by the use of familiar references. Considered are teaching the acidity of alpha-hydrogens of ketones, alkylation of amides and imides, and others. (CW)

Described is an undergraduate coordination chemistry experiment that enables students to relate concepts developed in class about the stereochemistry and coordination numbers to the interpretation of the electronic and infrared spectra and their magnetic behavior. Indicates that thermal decomposition and x-ray diffraction studies can also be…
