Presents eight examples from two elementary school science textbook series of misleading suggestions related to what students should observe during science lessons. Levels and page numbers are given for each example. Questions whether textbook authors have tried and analyzed the experiments they describe. (Author/SK)

Outlines procedures for constructing an instrument which uses an electrode and calibration methods to measure the salinity of waters in environments close to and affected by a saline estuary. (Author/DC)

Discusses advantages of using an estuarine environment as a study area for A-level students and reviews organizational considerations. Details and references regarding a variety of suitable techniques are provided along with examples of results obtained by students at Waltham Forest College. (Author/DC)

Describes a collection of college chemistry demonstrations designed for self-paced classes. Some of these exercises stem from original ideas; others are adaptations of one or more published demonstrations. Two exercises, as examples, are also included. (HM)

Summarizes scientific findings resulting from the Apollo missions, including lunar rocks and soil, age determination, and the moon's interior, evolution, and origin. Indicates experiments for future lunar research. (SK)

Describes the use and handling of alkali metals in school laboratories and seeks to reexamine precautions which one may reasonably take before executing routine procedures since their use, even by skillful teachers, occasionally results in accidents in the form of violent explosions. (Author/SK)

Offers the opinion that the creative and imaginative dimension of chemistry can be added in chemistry instruction through the acknowledgement of ambiguity in experimentation and science history. (CS)

Describes experiments which can be completed in five four-hour laboratory sessions, including two synthesis (alpha-phenylbutyric and alpha-phenylbutyric acid anhydride) and determining the absolute stereochemistry of secondary alcohols using the synthetic products. (JN)

Describes an experiment as an alternative to undergraduate experiments limited to high temperature metal systems or lower temperature systems involving objectionable or unstable materials. Lists six advantages of the experiment. (Author/JN)

Describes a procedure for determining the coefficient of restitution using a microcomputer which collects and sends data to a large computer where analysis is done and graphical output is generated. The data collection hardware and software are described, and results are illustrated. (Author/SK)

Describes the phenomenological and microscopic aspects of solid-state diffusion in an electric field and presents a Monte Carlo method which is used to stimulate an atomistic model of diffusion in an electric field. The Nernst-Einstein relation is also discussed. (HM)

Describes an experiment in which acetaminophen is converted into phenacetin, that has been used at Shepherd College in an introductory chemistry course for nurses and in the organic chemistry laboratory. (BT)

The use of microcomputers in the undergraduate chemistry laboratory is presented. Examples are included which can be implemented in the PET 2001. (SA)

Describes various experiments which high school students are preparing, to be carried on NASA's 500 or more Space Shuttle flights in the 1980s. The project is intended to stimulate superior secondary school students. (SA)

Described is a one-week summer chemistry workshop held at Lebanon Valley College, Annville, Pennsylvania, for secondary school students. Experiments and evaluation results of the workshops are provided. (HM)
