Describes a physical chemistry experiment investigating the vapor-liquid equilibrium in a heterogeneous system. (SL)

Describes a nuclear magnetic resonance experimental example of spin tickling; also discusses a direct approach for verifying the relative signs of coupling constants in three-spin cyclopropyl systems. (SL)

Describes an experimental method of measuring the molecular weight and subunit corporation of an oligomeric protein. (SL)

Six questions are listed that concern subject matter ranging from toxicity and biochemistry to insect physiology and physics. These questions may be used for study, review, or examination. Answers are also given. All of the questions relate to chemistry and may be adapted to different grade levels. (MR)

An integrated physical-analytical-inorganic chemistry laboratory procedure for use with undergraduate biology majors is described. The procedure requires five to six laboratory periods and includes acid-base standardizations, potentiometric determinations, computer usage, spectrophotometric determinations of crystal-field splitting…

Discusses innovations in the presentation of general chemistry catagorized via media, computers, and applied psychology. (SL)

Describes methods for the initial presentation of chemical colligative properties via an easily acceptable intuitive method. (SL)

Discusses safety aspects of the new chemistry building being built at the University of Akron. (SL)

Describes the Science Olympiad conducted yearly by St. Andrews Presbyterian College as a method of recruiting science oriented students. (SL)

Describes a simple chemistry laboratory experiment which allows students to calculate thermodynamic values. (SL)

Describes a laboratory kinetic experiment which demonstrates the important phenomenon of general catalysis by bases and/or acids. (SL)

Compares results in organic chemistry during the first year in a polytechnic school with a separate survey of sixth-form achievement. The findings are discussed in terms of the implications for post-A-level chemistry, the debate on chemical nomenclature, and the application of Piagetian concepts to chemistry courses. (Author/CP)

Describes a 12 hour minicourse in Huckel molecular orbital (HMO) theory presented as part of a senior level chemical bonding course. (SL)

Describes chemistry games included in the PLATO computer-generated graphics system developed at the University of Illinois to give students problem solving practice. (SL)

Describes an experiment for determining the thermal neutron flux of the light-water nuclear reactor at the University of California, Irvine. The difficulty of the activity can be varied to match the student's level of proficiency. (SL)
