The lack of bilingual instructional materials is acute for speakers of Asian and Pacific Island languages. Mathematics and science materials are virtually nonexistent. Social studies materials must be expanded from their present supplementary forms. Language materials must be revised to provide students a practical, working fluency in the non…

Presents an introduction to plankton, describing the various plants and animals that make up this group of living things. Suggests that plankton can be an important introduction to marine biology and an intriguing study to stimulate the curiosity of students. (BB)

The effects of varied concentrations of petroleum products on marine animals are tested. (CP)

The distribution, nesting and brooding habits, and migration patterns of the wood duck (aix sponsa) are described. (CP)

Reviews classroom teaching ideas including burning sugar cube experiments, science library reference materials, and growing salt crystals. (SL)

Provides a listing of sources of literature and teaching aids to improve course content in the fields of: weak interactions, beta decay, orbital electron capture, muon capture, semileptonic decay, nonleptonic processes, parity violation in nuclei, neutrino physics, and parity violation in atomic physics. (SL)

Describes apparatus utilized to demonstrate physics principle. Equipment described includes a low pressure chamber, a 360 degree loop ramp, a tilted table demonstrating motion principles, and a method for casting a three dimensional display of magnetic lines of force. (SL)

Science is an often ignored subject in the elementary grades. This article lists and briefly discusses ten suggestions for strengthening and enriching an elementary science curriculum. Among the ways given are science fairs, museums, outdoor learning centers, filmstrips clinics, and school weather stations. (MA)

Contains a partially annotated, nontechnical bibliography of recent materials about supernovae, including some about the discovery of a supernova in the Large Magellanic Cloud. Includes citations of general books and articles about supernovae, articles about Supernova 1987A, and a few science fiction stories using supernovae. (TW)

Reviews the usage of Genecon, a hand-operated generator, in science laboratory experiments, such as the relationship between motor and generator effects, the system's efficiency, Joule heating, and conversion of mechanical energy into electrical potential energy. Provides the address for purchasing the Genecon and accessories. (YP)

Describes a simple three-dimensional model of Halley's Comet orbit (which is much more informative than a two-dimensional drawing) to illustrate spatial relationships and visualize how the comet moves relative to the earth. Instructions for model assembly are given along with a template which can be photocopied and glued to cardboard. (JN)

Explains the use of an accelerometer in investigations confirming Newton's second law. Provides diagrams and descriptions of the apparatus. (ML)

Outlines steps for casting insects in permanent molds prepared from commercially available liquid plastic. Also describes dry mountings in glass, acrylic, and petri dishes. The rationale for specimen use, hints for producing quality results, purchasing information, and safety precautions are considered. (DH)

Illustrates a method by which individual students or small groups can make a compact, self-sufficient system supplying all the growth needs for bean sprouts. Outlines several activities that can be completed while the bean sprouts are growing. (DH)

Suggests how postage stamps can be incorporated into chemistry teaching. Categories considered include emergence of chemistry as a science, metric system, atoms (and molecules and ions), stoichiometry, energy relationships in chemical systems, chemical bonding, nuclear chemistry, biochemistry, geochemistry, matter (gases, liquids, and solids),…
