The unit presented in this teacher's guide is the first of two developed for the fifth year in the Science Curriculum Improvement Study (SCIS) curriculum. Attention is focused on energy transfers involved in the interaction of matter in solid, liquid, and gaseous forms. The chapters are presented in six parts which include activities for reviewing…

The author views the primary purpose of the modern engineering laboratory as teaching the student how to experiment. An attempt is made to update the engineering laboratory and make it generally meaningful for all students, whether headed for graduate school or an industrial job. The intent is to broaden the experimental picture so that students…

The publication presents outlines of some of the difficult experiments suggested in the chemistry syllabus for the Certificate of Sixth Year Studies in Scotland. The experiments included in the publication form a small part of the total experiments suggested in the syllabus. Simple experiments, the details of which are available in textbooks, are…

This report attempts to cut through the rhetoric of both the opponents and the proponents of performance contracting and to bring the main issues into focus. The report (1) describes different kinds of contracts; (2) discusses testing problems; (3) gives a description of the Texarkana and Banneker elementary school projects; (4) provides sample…

Much of the current research in experimental plant biology requires highly uniform plants. To achieve this, many plants are grown under conditions in which the environment is carefully manipulated. This pamphlet has been prepared, therefore, to present and describe growth procedures which will produce vigorous, healthy, uniform plant material in…

This paper emphasizes the need for empirical research and objective discovery procedures in semantics, and illustrates a method by which these goals may be obtained. The aim of the methodology described is to provide a description of the internal structure of a semantic field by eliciting the description--in an objective, standardized manner--from…

This manual is designed for use in the laboratory phase of courses dealing with microbial aspects of pollution. It attempts to cover the subject area broadly in four major categories: (1) microorganisms in clean and polluted waters, (2) carbonaceous pollutants, (3) nitrogen, phosphorus, iron, and sulfur as pollutants, and (4) sanitary…

The investigations for topics 9-14 in the earth science course developed by The University of the State of New York for secondary schools are contained in this supplement to the syllabus (ED 046 749). The topics in this supplement include the erosional process, the depositional process, the formation of rocks, the dynamic crust, interpreting…

THE EFFECTS OF SEVERAL STYLES OF SUPERVISION UPON THE PERFORMANCE OF INDIVIDUALS WERE EXPLORED IN A LABORATORY SETTING IN WHICH SELECTED ASPECTS OF SUPERVISION WERE EXPERIMENTALLY MANIPULATED. PARALLELING THE WORK SITUATION, THE EXPERIMENTAL SETTING INVOLVED A CHOICE OF TWO ACTIVITIES, EACH OF WHICH WAS REINFORCED. THE ROLE OF SUPERVISION WAS TO…

This paper deals with two problems confronting the applied researcher using a behavior analysis approach. The first is concerned with the need for independence of behaviors, subjects and settings. The effectiveness with which the researcher can solve this type of problem depends on the researcher's emphasis on the examination of procedures, and…

Subjects (N=43) aged 50 and more were tested on a Sternberg recognition-memory task to explore the relative effects of depression and altered brain function on short-term memory in later life. Many performance differnces were best accounted for by the additive effects of depression and educational background, rather than by either variable…

Describes a heat transfer experiment that demonstrates kinetic behavior using measurements of the rates of cooling and warming of liquids. (MLH)

Describes a college-level course on winemaking and brewing offered to both the academic and the non-academic community. Discusses fermentation and the processing of wine and beer. (MLH)

Describes an experiment that demonstrates the following principles and reactions: amphoterism, oxidation-reduction, equilibrium dependence on pH, solubility, and polymerization. The experiment involves the oxidation of chromium and the precipitation of a chromate salt. (MLH)
