This resource guide provides information for 13 laboratory experiments designed to be conducted in small schools with limited equipment and materials. For each experiment, the document outlines necessary equipment and materials, experiment procedures, and questions to be answered. The experiments are: (1) studying the properties of water; (2)…

This manual provides learning activities for use in two vocational agriculture courses--ornamental horticulture I and agricultural technology I. These activities are intended as aids in the teaching of application of science principles. An introductory chart gives a summary of how vocational agriculture objectives match objectives of specific…

The common links in language learning theory relating to school content areas are the notion of input comprehensible to the learner, the distinction between language usage and use, and the concept of cognitive/academic language proficiency in contrast with basic interpersonal communication skills. This suggests that a laboratory-based science…

This document presents a secondary level physics unit which introduces students to the Wheatstone Bridge, its use in determining the value of unknown resistors, and the effects of wiring resistors in series or in parallel. (SL)

Presented is a secondary level physics unit which introduces students to electrical resistance in series and parallel combinations, use of the voltmeter and ammeter, wiring simple circuits, and writing scientific reports. (SL)

Presented is a discussion of the events of the 20-year lapse between the invention of the pile in 1800 by Volta, and Hans Christian Oersted's famous definitive paper "Effects of a Current of Electricity on the Magnetic Needle." Students are thus enabled to appreciate the climate of the time and the manner and significance of Oersted's…

This paper focuses on the search for electromagnetic induction from 1820 to 1831 and the efforts by Augustin Fresnel's colleague, Andre Marie Ampere, in electric and magnetic induction. Faraday's work is discussed with excerpts from his diary on electromagnetism. A variety of different experiments by researchers including Francoise Jean Arago,…

This paper focuses on Michael Faraday's experimental research in electricity in the 1830's. Historical notes related to his work are included as well as experiments, his objectives, and illustrations of equipment for the experiments. Examples from his diary are given so that students can attempt to emulate his honest and systematic manner of…

This report describes National Institute of Health policies on animal welfare, the 1976 amendment to the Animal Welfare Act, and relevant portions of the Endangered Species Act of 1973. It is divided into four sections on the following topics: (1) laboratory animal management; (2) laboratory animal quality and health; (3) institutional policies;…

THE MERITS OF VISUAL AND AUDITORY STIMULI AT EACH STAGE OF THE LEARNING PROCESS WERE PRESENTED IN THIS WORKING PAPER. SPECIAL ATTENTION WAS GIVEN TO THE DIFFERENCES IN RESPONSES REQUIRED AT EACH STAGE AND THEIR CONTROL BY THE NATURE OF THE LEARNING TASK. THE PROBLEM WAS APPROACHED BY A CONSIDERATION OF THE BASIC PROPERTIES OF WORDS AND PICTURES…

Presented is a science activities in energy package which includes 16 activities relating to electrical energy. Activities are simple, concrete experiments for fourth, fifth and sixth grades which illustrate principles and problems relating to energy. Each activity is outlined in a single card which is introduced by a question. A teacher's…

Because of a reading difficulty resulting in inability to acquire new information and concepts from the textbook used in a technical Physics I course, the investigator felt it appropriate to find another way for presenting the material. Since these students were majoring in electronics technology, they require good technique in the laboratory. The…

Described are four demonstration/participation laboratories in which students analytically and experimentally evaluated various catheter-transducer blood pressure measurement systems. The activities were included in a graduate level course entitled "Theory and Techniques of Bioinstrumentation," taught by the Department of Electrical Engineering…

Topics dealing with biology teaching are presented in this quarterly review. Major entries include contributed articles on "Take-Home Laboratory Activities: One Answer to the Time and Space Problem,""Application of a Cooperative University/Middle School Model to Enhance Biology Education Accountability," and "A Report on Computers in Biological…

A total of 20 children, between 17 and 38 months old, were observed in their day care centers and in a standardized laboratory procedure. In both settings, preseparation, separation, and reunion situations were observed. Observers coded proximity-increasing and proximity-decreasing behaviors to mother and to other adults; in addition, distress,…
