Five experiments and 19 activities are presented in this Unit 5 handbook. The experiments are related to electrolysis, charge-to-mass ratio, elementary charge determination, photoelectric effects, and spectroscopic analyses. The activities are concerned with Dalton's theory, water electrolysis, periodic tables, single-electron plating, cloud…

Basic atomic theories are presented in this fifth unit of the Project Physics text for use by senior high students. Chemical basis of atomic models in the early years of the 18th Century is discussed n connection with Dalton's theory, atomic properties, and periodic tables. The discovery of electrons is described by using cathode rays, Millikan's…

Teaching procedures of Project Physics Unit 5 are presented to help teachers make effective use of learning materials. Unit contents are discussed in connection with teaching aid lists, multi-media schedules, schedule blocks, and resource charts. Brief summaries are made for transparencies, 16mm films, and reader articles. Included is information…

The purposes of this study were: (1) to identify and state those behaviors which, in the opinion of various scientists and science educators as expressed in their written statements, might foster an understanding of science and a positive attitude toward science; and (2) to determine which scientific behaviors as exhibited by students in selected…

In this study an experimental test was constructed requiring high school students in introductory physics to use graphic rather than verbal skills in identifying relational concepts of physics. The effectiveness of the test was examined using both traditional and contemporary-PSSC (Physical Science Study Committee) physics. Two hundred twenty-six…

The purpose of this study was to compare the level of concept attainment achieved by students enrolled in a Physical Science Study Committee (PSSC) physics course with that achieved by students enrolled in a traditional high school physics course. A sample of 265 PSSC students and 219 enrolled in the traditional course participated. The instrument…

This syllabus gives a day by day descriptive account of the activities and subjects covered during a two-week in-service program on astronomy, physics, and Florida geology for teachers of grades one through nine. The program for the astronomy and physics was designed to accommodate four levels of instruction: Grades 1 and 2; Grades 3 and 4; Grades…

Recommendations for radiation shielding, protection, and measurement are presented. This handbook is an extension of previous recommendations for protection against radiation from--(1) high energy and power electron accelerators, (2) food processing equipment, and (3) general sterilization equipment. The new recommendations are concerned with…

A discussion is presented of the importance of science in the school program, the objectives of science teaching, and facilities for science instruction. Descriptions are then presented regarding the size and facilities necessary for the general science room, the darkroom, the biology room, the physics room, and the chemistry room. Two diagrams…

This study attempted to ascertain if the elements perceived in the physics concepts of mass and weight differed for students of different cultural backgrounds. Responses of two matched groups of 19 students each, one from the United States and the other from Taiwan, were studied; students were given word association tests and a physics problem set…

This study describes the duties and responsibilities of the medical physicist and estimates the number of medical physicists needed in the next decade. A questionnaire, sent to members of the American Association of Physicists in Medicine, was designed to cover: characteristics of medical physicists, nature of work in medical physics, distribution…

Reported are the results of an eight-item questionnaire survey of 31 educators (high school teachers and others) representing a nationwide sample of individuals believed to be currently involved in a unified science program at the high school level (grades 9-12). This survey was designed to determine the relationship of unified science to…

The experiment was designed to study the effects of an instructional strategy on prospective elementary school teachers receiving a course in the modern concepts of physics. The study involved two classes, both of which were taught with the same teaching method. The concepts presented were different. Those considered as traditional content…

This report describes four individualized programs which simulate physical experiments in force and motion, graph and data collected by individual students, and provide feedback to each student relative to his generalizations. An overview of the unit is provided, descriptions of the unit and accessory materials are presented, sample runs of the…

Reported is a study to measure the degree to which children have developed an understanding of basic physics. The instruments contained items in a multiple choice format with a stem picture depicting an actual happening and three choice pictures, one of which was true in relationship to the stem. Items for the test were drawn from basic science…
