Four science education fact sheets are presented and focus on: (1) creationism vs. evolution; (2) science careers; (3) science activities for special students; and (4) the role of the laboratory in science teaching. The first fact sheet was prepared to assist teachers, curriculum coordinators, and others in dealing with the teaching of evolution…

Summarizes the advantages in using the Daedalon Air Table, which supplies compressed air to the pucks instead of the table surface itself. Describes methods for constructing an electronic null detector using a Weston type galvanometer and an integrated circuit operational amplifier. Also describes a redesigned and improved sound-level meter. (CS)

Lists equipment and materials needed and procedures for analyzing soil, in which secondary school students experience practical applications to acid-base reactions, pH, oxidation-reduction, precipitation and solubility. (CS)

A bibliography and short historical background are provided within this description of the integrated science thrust in science education. Detailed are the philosophy and methodology as outlined by FUSE, the Federation for Unified Science Education. (CS)

Outlines a variety of laboratory procedures, techniques, and materials including construction of a survey frame for field biology, a simple tidal system, isolation and applications of plant protoplasts, tropisms, teaching lung structure, and a key to statistical methods for biologists. (DS)

Outlines several laboratory procedures and demonstrations including electric fields using sawdust, experiments with capacitors, particle spacing in a vapor and a liquid, metrology, momentum, Moire patterns and interference fringes, equipping for practical electronics, and using programmable calculators for rapid plotting of graphs. (DS)

Offers suggestions for activities that demonstrate the principles of osmosis. Explains how decalcified chicken eggs can be used to give students practice with measurement, experimental procedures, and science principles. (ML)

The Nevada Science Standards represent a common core for curriculum throughout Nevada's schools. The Nevada Science Standards are intended to provide Nevada students with a rich, thorough, and varied science education to prepare them for the challenges, discoveries, and demands of life in the 21st century. The two main sections of the document…

Describes a physical chemistry experiment that introduces undergraduate students to the entities of polyelectrolytes. (CS)

Written for classroom teachers as well as preservice teachers, this book provides information, methodologies, and discussion intended to help educators develop and modify their own philosophy of science and science teaching. Part I examines reasons for teaching science, the intellectual and emotional development of children and their implications…

People have gazed up at the cosmos for thousands of years and wondered about the wanderers of the heavens: the planets. The past 20 years have been the golden age of planetary exploration because of many expeditions, most notably the Voyager and other unmanned space craft. This document is a summary of the information known about the planets of…

Provides an alternative derivation of the Boltzmann distribution based on the minimization of the Helmholtz free energy. (CS)

Provides information concerning the Boltzmann distribution mentioning partition functions, spectroscopy, basic mathematics, and its relation to temperature distribution. (CS)

Presents and discusses a procedure for estimating the dissociation energies of diatomic molecules by taking into account experimentally observable parameters. (CS)

Summarizes two research studies on: (1) suitability of science reading materials at CSE and O levels, and (2) effects of single sex and coeducation on science subject (N=1200) preferences and choices at 14+. Discusses spider diagrams, what is science, and problems and solutions in chemistry teaching in post-16 institutions. (DS)
