Describes an oscillating electroscope, an apparatus to verify the time interval between successive events in nuclear decay, and electronic circuits that are the analog of consecutive reactions. (SL)

Describes an experiment studying the decay of moth balls to demonstrate diffusion phenomena. (SL)

Describes a freshman physics laboratory experiment for approximating the mean free path in high density gases by measuring the mean free path of hockey pucks on an air table. (SL)

Describes an undergraduate experiment which will permit students to analyze the rotational Raman spectra of hydrogen and carbon dioxide and determine the bond distances. (SL)

Describes an experiment for determining the amount of BHA in cooking oil in an undergraduate level chemical technology program. (SL)

Describes physics laboratory apparatus including devices to demonstrate projectile motion, glass cutting, and a pendulum clamp. (SL)

Section five lists main dealer locations and main branch offices by region and state. Canada and Puerto Rico are included in this section. Following each state or country, the listings are alphabetical by city. Addresses are given. (MA)

Describes demonstrations, some apparently paradoxical, which can be performed with commercially available magnetic stirrers. (SL)

Presents a triple pendulum used to demonstrate normal modes. Also discusses the mathematical similarity of the equations of three coupled quantum mechanical levels. (SL)

Describes an experiment for studying the dynamics of a soft spring. (SL)

Discusses the language laboratory within the context of various theories of second language learning and in relation to its value in language learning, specifically in terms of the pattern drill. (Text is in French.) (AM)

Describes a technique for isolating slime molds from tree bark and outlines projects for working with slime molds in the laboratory. Diagrams of 26 of the more common British species and a key to the Orders of Myxomcetes are given. (CS)

The hands-on science approach and lab classroom used by the Horace Mann School in the District of Columbia to teach blind, deaf, and emotionally disturbed children are described. (BT)

Explains the laboratory techniques and equipment necessary for the demonstrations. (CP)

Discusses the news programs of "Landesbildstelle Berlin," as providing dialog material useful for the language classroom. The dialogs deal with news, rather than simply providing examples of language structures. Discusses also difficulties of using dialogs in the laboratory. Examples and hints for application are given.
