An inorganic chemistry course at the Free University of Amsterdam is part of an integrated program involving practical work and theoretical study for chemistry students. Twelve experiments are required and 11 are performed by students in groups of fours. (Author/SA)

Describes the use of cassette tape recordings in preparing freshman chemistry students for experiments in laboratories. The tapes are said to have decreased student anxiety in the laboratory and increased laboratory skills. (SA)

Describes an elastic Foucault pendulum designed to demonstrate how the rotation of the plane of oscillation depends on geographical latitude, and shows that this rotation vanishes at the equator. (GA)

Describes how to measure Brewster's angle using Polaroid sunglasses and the reflection of the ceiling light on a polished floor. (GA)

In this experiment, the student duplicates the experiment reported by Wohler in 1828. (BB)

In this experiment, benzylic hydrogen reactivity is used to prepare dimers of a variety of alkyl benzenes, and the benzylic hydrogen reactivity of these compounds are compared. (BB)

This simple two-phase procedure for the oxidation of secondary alcohols to ketones is applicable to a wide variety of substrates and is also ideally suited for the undergraduate laboratory. (BB)

Describes a titration procedure done in glacial acetic acid. (BB)

Describes a college level introductory oceanography course that incorporates a hands-on laboratory component. The activities include the determination of density and buoyancy, light transmission in sea water, and wave refraction. (MA)

Describes use of tail muscles and spinal cord in the tadpole as an alternative source for muscle-and-nerve experiments. Includes explanation of simple dissection and preparation of tadpole; instructions for experiments such as threshold, strength of stimulus, frequency of stimulus, single twitch, tetanus, fatigue, effects of temperature on…

Pigeons learned discrimination rapidly and responded differentially to pictures seen for the first time. The essential feature of a natural discrimination--which is the ability to cope with natural ranges of variation--was approached and earlier experimental results were extended using other classes of stimuli. (Author/RK)

If a motive for cognitive consistency and the extravert's preference for the arousing and novel are opposing tendencies, one would predict that highly extraverted individuals will show less preference for states of cognitive consistency than those who are less extraverted. Two experiments test this prediction. (Author/RK)

Focuses on the effect of verbal and pictorial stimuli on paired associate learning. The discussion centers on the traditional finding that learning is easier with pictures than with words as stimuli. Hypothesizes that this effect is caused by differential coding and storing strategies for words and pictures. (Editor/RK)

Two experiments are presented in which lateralization of monaural, auditory input affected the evaluation of verbal passages. Discusses lateral differences in evaluating auditory stimuli in the framework of the left hemisphere's specialization for the holistic processing of objective information and the right hemisphere's specialization for the…

Several experiments investigated the effect of word length on recognition thresholds for both familiar English words and unfamiliar pseudowords, the thresholds measured both with and without a stimulus mask. (Editor)
