Secosky, James J. – Science Teacher, 1989
Discusses the missing water on Mars. Describes five experiments simulating conditions on Mars: (1) behavior of dry ice; (2) low-pressure vacuum; (3) freezing point depression; (4) water in hydrated minerals and clay; and (5) properties of carbon dioxide. (YP)

Snyder, Evan S. – Physics Teacher, 1985
Provides a method for correcting the photoemission from a collector when using the photoelectric effect experiment to determine Planck's constant. The problem results from a negative current through the cell and makes the measurement of the cutoff potential difficult. (DH)

Peer reviewed Peer reviewed
School Science Review, 1987
This section of the journal includes several short notes on science activities and materials for secondary schools. Activities and materials are included that relate to biology, microbiology, microcomputers, chemistry, and physics. (RH)
Descriptors: Biology, Chemistry, Microbiology, Microcomputers

Brody, Howard – Physics Teacher, 1985
Presents information on the moment of inertia of a tennis racket about its principal axes. This information (not available from conventional sources) is useful since it influences how the racket plays and how the racket feels when it is swung. In addition, measurements of motion can be easily made by undergraduate students. (JN)

Mooney, Robert J. – Physics Education, 1985
Presents a nonmathematical approach to help students understand that there are two types of coherence and to associate coherence as a property of the illumination at an object itself. The approach also lends itself to an introduction to the Fourier approach for analyzing imaging systems. (JN)
Descriptors: College Science, Higher Education, Light, Optics
Soltow, Willow – Humane Education, 1985
Surveys careers in working with animals and gives suggestions for use of this topic in the classroom. Activities involve identifying reasons for choosing any career, careers involving animals (traditional and nontraditional), community personnel, and pros and cons of animal careers. Two student activity sheets are included for duplicating. (DH)
Descriptors: Animal Caretakers, Animals, Career Awareness, Careers

Jones, Edwin R., Jr.; Childers, Richard L. – Physics Teacher, 1984
Discusses the development of the concept of atomicity and some of the many which can be used to establish its validity. Chemical evidence, evidence from crystals, Faraday's law of electrolysis, and Avogadro's number are among the areas which show how the concept originally developed from a purely philosophical idea. (JN)

Muller, Ernest H. – Journal of Geological Education, 1984
Materials as ordinary as glacial till often afford instructive resources for classroom demonstration, field study, and laboratory analysis, rewarding the investigator with information about provenance, glacial transport history, environment and mode of deposition, and possible postglacial diagenesis. (Author)
Descriptors: College Science, Geology, Higher Education, Literature Reviews

Hall, Donald E. – Physics Teacher, 1985
Reviews the basic properties and evidence for their existence. (The sequel will consider the consequences if a human being had opportunity to interact directly with a black hole.) (JN)
Descriptors: College Science, High Schools, Higher Education, Physics
Peer reviewed Peer reviewed
Chemical and Engineering News, 1985
Indicates that periodic table users will see changes in group notation as publishers and authors adopt revisions that already have been made or are being made. The revisions seek to remove ambiguities that have existed in that notation. A sample table is included which shows both old and new notations. (JN)
