Presents 15 suggestions for planning successful science fairs with younger children. Includes a list of ways in which the library can help. (SK)

With increasing changes in the roles of men and women, it has become important to gain a clearer understanding of the factors that influence sex-role development. This article is directed to teachers and contains suggested activities that will assist students in gaining insight into the processes of sex-role development. (Author)

Discusses various aspects of sea water, including: (1) the properties of sea water, (2) the law of relative proportions, (3) the ocean as a buffer, (4) the oxygen in sea water, and (5) the promise of chemical harvest from sea water. (CS)

Presents listings of selected reference materials relevant to symmetry and group theory in college physics and chemistry. Entries are classified according to a scheme involving 34 subject areas divided into four major groups. Comments on these materials and suggestions for future topics will be welcomed. (Author/SK)

Key resource materials, background readings, and informative organizations are suggested to teachers planning units or courses on the Nazi Holocaust. (SJL)

Presents an experiment on the bending of light in a medium with a continuously varying index of refraction. Several theoretical approaches for the analysis of this experiment, designed for college physics students, are also presented. (HM)

Describes a laboratory scale reactor that determines the kinetics of a gas-solid catalytic reaction. The external recycle reactor construction is detailed with accompanying diagrams. Experimental details, application of the reactor to CO oxidation kinetics, interphase gradients, and intraphase gradients are discussed. (CS)

Includes annotations of articles from previous issues of this periodical on the following topics: balancing equations and nomenclature, the mole, the silver tree experiment, and history of the periodic table. (CS)

The use of a "constructivist approach" in introducing the concept of equation in algebra is promoted and presented. (MP)

The use of the hand-held calculator for introducing geometric growth is illustrated. The activity is designed for secondary school mathematics students. (MP)

Presents an annotated list of resource materials useful for developing programs and materials about aging for elementary and secondary students. The list is divided into five categories: curriculum development, films/filmstrips, resource guides, organizations, and children's books. (KC)

Describes various resources indexed in the ERIC system that promote multiethnic perspectives in English instruction and English education, including introductory guides to multicultural education and programs for reading and discussion. (AEA)

Describes an air track experiment which involves a massive particle incident on a fixed wall with a light particle trapped in between. An analysis for this experiment, which is intended for junior and senior college students, is also included. (HM)

Presents four notes that report new equipment and techniques of interest to physics teachers. These notes deal with collosions of atoms in solids, determining the viscosity of a liquid, measuring the speed of sound and demonstrating Doppler effect. (HM)

The author discusses practical considerations of teaching linoleum block printing in the elementary grades (tool use, materials, motivation) and outlines a sequence of design concepts in this area for the primary, intermediate and junior high grades. A short list of books and audiovisual aids is appended. (SJL)
