Summarizes the efforts for developing guidelines for chemistry education, such as "Guidelines for Chemistry in the Two-Year Colleges" (1970); "Tomorrow" (1984); "Critical Issues in Two-Year College Chemistry" (1986); and "Guidelines for Chemistry and Chemical Technology Programs in Two-Year Colleges" (1988).…

Applies the concept of entropy to aging, evolving systems, inanimate systems such as corporations, and structural complexity for classroom teaching. Presents many mathematical expressions as well as explanations. Lists 37 references. (YP)

Discusses 27 chemical demonstrations involving inexpensive, readily available materials that illustrate the following concepts: acid/base properties, gas properties, characteristics of carbon dioxide, chemiluminescence, freezing point depression, heat of vaporization; density, polymers, surface tension, polarity/nonpolarity, UV absorption,…

The effect of equations in scientific proofs on readers' comprehension was studied. Forty college undergraduates solved unfamiliar physics problems with or without a traditional series of related equations. Verbal proofs produced better responses than did equation-based proofs. Equations in proofs cause readers to shift attention away from…

State geological surveys have a significant role in geologic education. They are the principal gatherers, evaluators, and distributors of geologic information within their states; and they are in daily contact with the public through state, government, industry, and educator contacts. Many surveys are attempting to disseminate information through…

Examined are ways in which beliefs and values arise in science education specifically, though not exclusively, involving Christian connections. The nature of science is discussed and one textbook's treatment of the Galileo Affair is considered. (Author/CW)

Extension activities involving the ballistic pendulum beyond its typical use in physics instruction are presented. The construction of apparatus, procedures, and probable results are discussed. (CW)

Describes the use of an inexpensive device consisting of a plastic soda bottle and a modified plastic cap in a range of demonstrations and experimental activities having to do with the behavior of gases. (Author/WRM)

Observes 16 students from five elementary science classes to examine how students use tools when constructing new knowledge during science instruction, how control of tools is actualized from pedagogical perspectives, how language and tool accessibility intersect, how gender intersects with tool use, and how competition for resources impacts…

To learn how e-prints are cited, used, and accepted in the literature of physics and astronomy, the philosophies, policies, and practices of approximately 50 top-tier physics and astronomy journals regarding e-prints from the Los Alamos e-print archive were examined. Results provide a sense of the current impact of the evolution of e-prints on the…

This study investigated preschool science environments in 20 preschool classrooms (N=20) in 13 midwestern child care centers. By operationalizing Neuman's concept of "sciencing," this study used The Preschool Classroom Science Materials/Equipment Checklist, the Preschool Classroom Science Activities Checklist, and the Preschool Teacher…

Project AIMS (Activities to Integrate Mathematics and Science) has as its purpose the integration of subject matter in grades K-9 on the premise that such integration enriches and makes learning meaningful and holistic. In fact, extensive field testing of the curriculum materials produced by AIMS has confirmed that integration produces the…

This book provides five instructional units on groundwater. Units included are: (1) "Where's the Groundwater?" (describing the concepts of a saturated zone, water table, hydrologic cycle, recharge and discharge, core of depression, subsidence, and saltwater intrusion); (2) "How Does It Travel?" (discussing porosity,…

This guide describes six bubble activities for developing a variety of process skills in grades 5-9. Activities included are: (1) "Bubble Technology"; (2) "Comparing Bubble Solutions"; (3) "The Chemistry of Bigger Bubbles"; (4) "Bernoulli's Bubbles"; (5) "Predict-a-Pop" for studying interference;…

This book is written for children 5 through 10. Part of a series designed to develop their curiosity, fascinate them and educate them, this volume introduces the habits of a variety of animals during the winter. Topics include: (1) surviving during winter, including concepts such as migration, hibernation, and skin color change; (2) changing…
