Describes construction of an inexpensive wind tunnel and a water manometer; experiments with model airplanes; and the calibration of the manometer and its use to measure wind velocity and lift on an airplane wing. Additional experiments with an electric fan are suggested. Diagrams are included. (GH)

A capacitor is discharged to generate an acoustical pulse and start a digital counter which is stopped by a microphone. Differences are accurately measured by positioning the sensing microphone on an optical bench. Results are discussed and extended experiments are suggested. The sources of some components are given.

Describes a cell that is free-standing and facilitates the collection of evolved gases in test-tubes. A similar cell is used to demonstrate the Kellner-Solvay electrolysis of brine. (GS)

This is the final report of the evaluation of Project CAUSE, a three year project to improve the laboratory portions of undergraduate physics courses at North Texas State University. The report is divided into six sections. Included in the overview are goals and purposes, the instructional format, and the evaluation plan. Demographic profiles…

Longitudinal and intervention laboratory studies were conducted to investigate the effects of viewing televised violence on the aggressive behavior of elementary school children. In the longitudinal study 505 children were studied over a 3-year period. The measures used included peer nominated aggression, aggression anxiety and popularity,…

This guide is designed to assist teachers in involving students in individual or small group laboratory investigative experiences in the life sciences. Each of the 22 experiments contains a prelab and postlab section for teachers and a detailed procedures section for students. (Author/CO)

This workbook contains laboratory exercises designed for use in a college introductory biology course. Each exercise helps the student develop a basic science skill. The exercises are arranged in a hierarchical sequence suggesting the scientific method. Each skill facilitates the development of succeeding ones. Activities include Use of the…

This paper discusses ways managers can motivate their employees to work and at the same time to increase their performance. Two theories of motivation--Vroom's theory and Atkinson's theory--focus on the use of extrinsic and intrinsic rewards respectively. A managerial strategy that combines the best of both intrinsic and extrinsic approaches to…

A SEARCH OF RECENT SCIENCE EDUCATION LITERATURE WAS MADE TO DETERMINE TOPICS IN PHYSICS AND CHEMISTRY THAT WOULD BE TESTED FOR SUITABILITY WITH PROSPECTIVE ELEMENTARY SCHOOL TEACHERS. EIGHT CRITERIA WERE SELECTED AND USED TO GUIDE THE WRITING OF LABORATORY ACTIVITIES. SIXTY-NINE PROSPECTIVE ELEMENTARY SCHOOL TEACHERS USED THE EXPERIMENTAL…

The purpose of this study was to develop and evaluate a series of simulation dialogs utilizing certain computer capabilities. The series of simulations produced in the study parallel the fundamental, inductive experiments developed by the Physical Science Study Committee (PSSC) through which students generalize Newton's Second Law. Students…

Ten experiments and 27 activities are presented in this handbook. The experiments are related to collisions, energy conservation, speed measurements, thermometry, calorimetry, gas properties, wave motions, and acoustic problems. The activities are concerned with stroboscopic photographs in collision, elastic impact, mass conservation, exchange of…

This is a National Trial Print of a unit on plants produced as a part of the Australian Science Education Project. The unit consists of an information booklet for students, a booklet for recording student data, and a teacher's guide. The material, designed for use with students in the upper elementary grades, takes from 15 to 20 forty-minute…

A review of some recent educational and research activities is presented in this publication. Major articles compiled in this review include: An Innovative Approach to Laboratory Instruction; An Evaluation of the Mastery Strategy for General Biology Students, Food Science as a General Education Course in Biological Science; The Phase Achievement…

A computer-based Statistical Program to Assist in Teaching Statistics (SPATS) has been successfully developed to aid the teaching of statistics to undergraduates with business and economics majors. SPATS simplifies the problem of experimentally creating and analyzing a variety of populations and of selecting and analyzing different kinds of random…

Included in this set are the teacher's guide and the four student laboratory manuals for the seventh grade science program, "A Search For Structure." The program has three phases, each consisting of student-centered, investigative activities. There are two subject area options in phase one: option A, Rocks and Minerals; and option B, Insects. The…
