Project Physics Teacher Guide 5, Models of the Atom.

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 about the background and development of each unit chapter, procedures used in demonstrations, apparatus operations, notes on the student handbook, and an explanation of film loops. Additional articles are concerned with relative atomic mass determination, spectroscopic experimentation, Rutherford scattering, angular momentum, and Nagaoka's theory of the "Saturnian" atom. A phototube unit and a Millikan setup are analyzed, and a bibliography of reference texts and periodicals is given. Solutions to the study guide are provided in detail, and answers to test items are suggested. The fifth unit of the text, with marginal notes on each section, is also compiled in the manual. The work of Harvard Project Physics has been financially supported by: the Carnegie Corporation of New York, the Ford Foundation, the National Science Foundation, the Alfred P. Sloan Foundation, the United States Office of Education, and Harvard University. (CC)
