Questions the percentage of science in the college curriculum and discusses the needs of science for progress. First published in 1957. (YDS)

Pinpoints common areas of neglect in considering science safety. Familiar hazards are discussed, with special consideration of improper chemical storage, old and unlabeled chemicals, and faulty circuits and equipment. An appendix lists basic safety rules and presents a checklist for general laboratory safety. (CS)

Presents a chemical instrumentation laboratory experiment that introduces the methodology of the fabrication and evaluation of an ion-selective electrode. (CS)

Presents methods by which undergraduate students gain practice in ESR spectroscopy. (CS)

This collection of articles, originally published in national and international journals, is fifth in a series devoted to trends in teaching chemistry. The volume is divided into nine sections, each with an introduction explaining why papers have been selected and outlining their particular interest. Section I provides a list of atomic masses,…

Describes a companion experiment to the experimental study of the di-iodide visible absorption spectrum. Experimental details, interpretation, and data analysis are provided for an analysis of the di-iodide fluorescence excited by a visible laser, using a Raman instrument. (CS)

An annotated list (books, magazines, and media) of sources of free and inexpensive science materials is provided, including addresses and costs (if any). (SK)

Describes a student project in analytical chemistry using sheet silicates. Provides specific information regarding the use of phlogopite in an experiment to analyze samples for silicon, aluminum, magnesium, iron, potassium, and fluoride. (CS)

Provides a brief history of electrets and describes how they can be made in a small laboratory. Also summarizes the uses of electrets and suggests projects and experiments with them. (CS)

Describes the construction of an apparatus that demonstrates that electrostatic forces can be large and also gives some idea of dependence of electrostatic forces between charged parallel discs on potential differences and separation. (CS)

This guide was developed for use by individuals with little or no botanical training who wish to identify native ferns of New York, New England, New Jersey, and Pennsylvania. A random access key, developed by the author, provides multiple pathways for identification of 60 species in 29 genera of ferns. (CS)

A description and short extract are given of a tabulated history of astronomy, in which particular emphasis is placed on the interaction of astronomy with various disciplines. (Author/SK)

Selected materials needed to teach an astronomy unit as well as suggested procedures, activities, ideas, and astronomy fact sheets published by the Manitoba Planetarium are provided. Subjects of the fact sheets include: publications and classroom picture sets available from the National Aeronautics and Space Administration and facts and statistics…

This book presents the facts, history, names, and dates behind 1,250 major accomplishments in science and technology. Each topic is covered in understandable paragraphs of 150 to 600 words and is intended for students, librarians, science instructors, and the general public. Four indexes provide access to the entries by year, name of discoverer or…

This information packet on quasars consists of an introductory paper, four articles from "Mercury," a journal of the Astronomical Society of the Pacific, and a bibliography. Methods used to measure distances in the universe and the nature of quasi-stellar objects (QSO's), the name preferred by many workers in the field, are discussed in…
