Describes an experiment for advanced-level undergraduate students for extending student experiences involving recording and interpreting infrared (IR) and nuclear magnetic resonance (NMR) spectra from reactions of organometallic compounds. Experimental procedures, analyses and structural assignments, and suggestions for extension and modification…

Presents an activity for upper elementary students called "Soil Structure and Ground Water." Provides procedures, materials, key concepts, background, and extensions. (YP)

Reviews three videotapes for physics teachers: (1) "Determination of the Newtonian Constant of Gravitation" showing the Cavendish experiment; (2) "Preview Film for RAM-Tutor Media" introducing a series of seven videocassettes covering physics; and (3) "Determination of the Velocity of Light" using a rotating mirror. (YP)

Discusses some incorrect representations of electric fields in textbooks. Considers total charge or charge density and two- or three-dimensional diagrams. (YP)

Described are six multipulse experiments with an emphasis on their application to common problems in chemistry. Exercises in relaxation time measurement, spin echoes, and polarization transfer are proposed. (CW)

Directions for the construction of an electronic version of an electroscope are provided. Demonstration and operation of this apparatus is discussed. A list of components and a schematic diagram are provided. (CW)

Reviews three computer software packages: "Mystery Objects," a science inquiry series for grades one-four; "Physics," covering physics content for high school and introductory college level; and a tutorial program "Sensei Geometry." Required hardware, price, and addresses for each software package are listed. (YP)

This article analyzes how science classes carry ideological elements and how that has ethical and deontological consequences with respect to science teaching. Provided are some examples of ideologizing, presenting a worldview, biased contents, and biased image of science. (YP)

Discusses a wall chart, "The Standard Model of Fundamental Particles and Interactions," for use in introductory physics courses at either high school or college level. Describes the chart development process, introduction and terminology of particle physics, components of the chart, and suggestions for using the chart, booklet, and…

Evaluates seven courseware packages covering the topics of fluid dynamics, kinetic theory, and thermal properties. Discusses the price range, sub-topics, program type, interaction, time, calculus required, graphics, and comments of each courseware. Selects some packages based on the criteria. (YP)

This study examined the impact of a biology course emphasizing computer simulation on student achievement and student attitudes toward science. The students in the experimental group were placed in a class limited to 16 students to have 2 students to each computer. (YP)

Investigates whether enriching text with analogies, similes, and metaphors has an impact on student cognitive learning and attitudes. Reports no gain on achievement, negative gain on attitude, no gain on proposition recall test, and negative gain on student attention to the text. (YP)

Describes a course for discovering whether rapid technological development can be compatible with a set of traditional cultural values. Outlines the background, summary, assignments, and lessons used in the course. Provides a course syllabus, schedule of assignments, and sample essay examination questions. (YP)

Described are videotapes for elementary school teachers. Outlines seven examples of demonstrations from physical science. Provides information on how to obtain the tapes. (YP)
