Over the past 20 years 164 children and educators have been reported as injured in demonstrations using flammable solvents. The injuries were the result of flash fires, flame jets, and projectiles which occurred once control was lost by the presenter. "The rainbow demonstration" using methanol as the solvent has by far been the most…

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)

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)

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 book, intended to serve as a resource guide for teachers wishing to implement computer-based learning in their own classrooms, is a collection of 29 classroom tested instructional programs designed to supplement an introductory chemistry course, regardless of text or approach. The programs cover a wide range of topics, from metric units of…

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…
