Observations and experiments with mice, developed and tested at the Pennsylvania Advancement School with underachieving boys in grades seven and eight, are described in this teachers' guide which includes copies of student worksheets for exercises needing them. In addition to lists of materials and procedural suggestions, ideas for guiding…

This method uses the cathodic deposition of silver from a cyanide solution in a non-partition cell with stainless steel electrodes. (BB)

This article describes the design, preparation, and initial evaluation of a set of computer-simulated chemistry experiments. The experiments entailed the use of an atomic emission spectroscope and a single-beam visible absorption spectrophometer. (Author/IRT)

Details a laboratory experiment designed to extend the calcium PVC matrix membrane ion-selective electrode studies to complex formation equilibria. (Author/MA)

The method involves the dissolution of a small piece of metallic lithium in a small quantity of tertiary alcohol followed by addition to a mixture of the isocyanate and the tertiary alcohol in ether. This should be useful in organic chemistry laboratory courses for the identification of tertiary alcohols. (Author/BB)

The preparation of "p"-carboxystyrene from carboxybenzyl bromide in aqueous media is described. This is an example of a Wittig procedure that can be performed by students in one afternoon. (BB)

The Meerwein reaction is often omitted from undergraduate organic chemistry laboratory books. This experiment, the preparation of "o"-chlorocinnamic acid from "o"-chloroanaline, illustrates this section. (BB)

This safe and efficient procedure for the synthesis of N-substituted amides and hydrazides is a modification of the Schotten-Bausmann procedure in which the amine or hydrazide is replaced by the corresponding hydrochloride salt, and the use of alkali is eliminated. (Author/BB)

Examines the phenomenon of water drops that float on water at room temperature. Describes experiments that have been done to study this phenomenon. (MA)

Discusses the origin and existence of sediment layers in the Atlantic Ocean. (CP)

Describes the general thrust of deep-sea microbiology research. Discusses the existence of deep-sea food chains. (CP)

Reports on scientific research with rats which has found that electrical stimulation in areas of the brain can trigger behavioral effects similar to those produced by narcotic drugs. (CP)

Two physics experiments are described, One, involving a laboratory cart accelerated along a level surface, examines the concept of inertial mass in translation and the other, using a solid cylinder, measures the moment of inertia of a wheel. Equations and illustrations are included. (MA)

Discusses how the fast Fourier transform can be used as a teaching tool to introduce spectral analysis of sampled data by interactive minicomputer experiments. (MLH)

Describes an experiment on Doppler effects using air cars on a linear air track and a homodyne Doppler radar system. (SL)
