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)

Describes various procedures applicable to secondary school science classes, including: (1) constructing a centripetal accelerometer; (2) demonstrating weightlessness with a small scale apparatus employing a catapult; (3) teaching hexadecimal counting by using the fingers; (4) demonstrating oscillation and resonance in tuned circuits. (CS)

Presents a demonstration of wave behavior, and experiments of (1) the determination of the mechanical equivalent of heat, and (2) a "discovery" investigation based on the maximum-span staircase. (CS)

Since the major causes of accidents are carelessness and a negative or apathetic attitude towards safety, this guide was developed to facilitate safe, stimulating science laboratory activities by providing both general and specific safety information presented in 12 sections. Subject areas considered in these sections include: 1)…

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)

Describes 12 video films constituting the "What About" series of the Skills Essential to Learning project. Films begin with an introductory sequence showing a teenager using a particular science skill and concludes with a longer sequence showing a scientist using the same skill. Programs last 15 minutes and follow an identical format. (BC)

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)

This resource guide is designed to: (1) stimulate development of student energy research projects; (2) expose students to research problems important to Ohio's science- and engineering-related industries; (3) strengthen the working relationship between science, mathematics, and English teachers in promoting technical communication skills; (4)…

Outlines a variety of laboratory procedures, discussions, and demonstrations including polarizing power and chemical properties of copper and zinc, preparation of boron coordination complex, demonstration of amino-acid synthesis in the primordial environment, classification and reactions of carbohydrates, and four others. (DS)

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,…

Presents a variety of laboratory procedures, discussions, and demonstrations including centripedal force apparatus, model ear drum, hot air balloons, air as a real substance, centering a ball, simple test tube rack, demonstration fire extinguisher, pin-hole camera, and guidelines for early primary science education (5-10 years) concepts and lesson…

This 21-chapter methods textbook provides essential information, practical applications, and resource materials for prospective, beginning, and experienced science teachers, professional science educators, science coordinators, and science supervisors. Major topic areas addressed in the chapters include: the scientific enterprise and science…
