Describes two experiments in physics, using the same inexpensive apparatus, that may be performed as projects by high ability secondary science students. (JR)

A compilation of essays deals with two vital ethical issues: (1) in such matters as genetic research, human subject research, and behavior modification, the conflict between freedom in scientific research and protection of the immediate public; and (2) the question of whether ethical guidelines have to be developed for teachers, or academic…

Ten experiments and 27 activities are presented in this handbook. The experiments are related to collisions, energy conservation, speed measurements, thermometry, calorimetry, gas properties, wave motions, and acoustic problems. The activities are concerned with stroboscopic photographs in collision, elastic impact, mass conservation, exchange of…

This freshman chemistry lab relates stoichiometric problems to real situations. It requires students to measure the Fe impurity in reagent grade calcium chloride. (BB)

This experiment provides an excellent practical application of computer-controlled spectrometers. (BB)

Explains a laboratory exercise where 2-methylpyrazinepentacyanoiron (II) is synthesized by thermal and photochemical pathways. (GA)

Presents an experiment in which students prepare salt-water taffy, and concrete props for teaching weak acids and bases. (SL)

Provides an overview of an experiment on reaction kinetics of the anthracene-hydrogen system. Includes a description of the laboratory equipment, procedures, and data analysis requirements. Points out the advantages of the recommended technique. (ML)

Contends that demonstration lecturing is a valuable science teaching approach. Highlights the benefits of this technique and identifies sources of information for teachers. Provides a listing of popular science lectures suitable for chemistry classes. Describes in detail the "Major of Chemistry" demonstration. (ML)

Described is an inexpensive wave tank used to study the amplitude of tsunamis travelling down a channel of decreasing depth. A detailed discussion to theory and computations is included. (SL)

Describes a method for performing a thermodynamic "ice bomb" demonstration which is faster, simpler, and cheaper than commercially available demonstration devices. (SL)

Describes a chemistry experiment appropriate for the day before Christmas vacation. Students prepare candy canes by following a recipe written in chemical terms. This illustrates that food is composed of chemicals and that the processes involved in cooking are chemical and physical changes. (JR)

Describes a number of activities and experiments designed to add interest and increase understanding in the secondary school physics laboratory. (JR)
