Nine experiments and 17 activities are presented in this handbook. The experiments are related to the earth's size and orbit, Piton height, telescope operations, Mars and Mercury orbits, stepwise approximation, and models of comet orbits. Further naked-eye observations in astronomy are designed in connection with the sun, moon, and planet…

This study undertook to reconcile the views of cognitive and behavioral learning theorists on the issue whether learning without awareness (LWA) is possible, and if so, the circumstances under which it occurs. In Study One, two reinforcement procedures were compared in a structured verbal conditioning task. Study Two was a replication of Study…

Included are a wide spectrum of space science articles which were developed and classroom tested by junior high school teachers. Concepts are developed through the use of historical perspectives, representational models, demonstrations, and student activities. The major emphasis is on student activities. Frequent use is made of tables and graphs…

This handbook contains information that has been used in the high school laboratory by many teachers. Most of the experiments can be adapted for use as individual laboratory exercises or as teacher-student demonstrations. The resource material in this handbook should be helpful to all physics teachers as they continue to adapt their courses to…

Two concepts predominate in studies of spatial invasion: territoriality (personalization and defense of a fixed spatial area) and personal space (a portable area surrounding the individual, which is responsive to environmental change). Spatial invasions were carried out by occupying a marked seat (invade condition), and adjacent seat (adjacent…

This book presents an experimental approach to the teaching of biology in secondary schools. Starting with a unit on microscopy, the study centers on animals. The two particular examples taken are those of the rat and the rabbit. A number of experiments have been suggested on nutrition, circulation, respiration, sweat, excretion, skin, regulation…

The purpose of the study is to provide information concerning the self esteem of blacks and whites under conditions of integrative and segregative simulated work groups. Subjects were 96 undergraduate students, half black and half white, who performed three laboratory tasks. Ziller's self esteem scales were used to measure the self esteem of…

This publication, published quarterly by the American Institute of Biological Sciences, focuses on biology education in colleges and universities. Included in this issue are articles dealing with mini-investigative labs in microbiology for nonscience students, the effects of various components of the Keller system on student attitudes and…

Describes a number of undergraduate laboratory experiments that illustrate the science of alchemy as it was historically practiced. (MLH)

Describes a dry-lab experiment in which the student is provided with a set of fluorescence spectra of quinine for study and interpretation. (MLH)

Describes undergraduate experiments concerning three topics: oxygen carriers, nitrogen fixation, and metal activated enzymes. (MLH)

Describes a simple microwave interferometer capable of measuring small phase shifts. Proposes laboratory exercises involving the use of the interferometer in the determination of refractive indices of gases and the analysis of the reflection in a test chamber. (Author/CP)

Presents three activities: (1) the investigation of the purity and stability of nicotinamide and flavin coenzymes; (2) desk-computer fitting of a two-exponential function; and (3) an interesting and inexpensive solubility product experiment for introductory chemistry. (RH)

Describes an experiment in which a racemic mixture of a coordination compound is resolved. (MLH)

Describes an experiment which quantitatively determines glucose by a spectrophotometric measurement of the colored complex formed between glucose and an amine. (MLH)
