Describes a physical chemistry experiment which uses spectroscopy to measure the heat of formation of Na2SiF6. Discusses the opportunities for students to see the use of a familiar instrument in an unfamiliar application, emphasizing that there are often many ways to attack problems in science. (TW)

Presented are reviews of two computer software packages for Apple II computers; "Organic Spectroscopy," and "Videodisc Display Program" for use with "The Periodic Table Videodisc." A sample spectrograph from "Organic Spectroscopy" is included. (CW)

The authors used the Fagan Test of Infant Intelligence (J. F. Fagan, L. T. Singer, J. E. Montie, & P. A. Shepherd, 1986) to examine preferences for novelty and to evaluate several indicators of attention (off- and on-task indexes and durations) in 6- and 9-month-old infants who had been prenatally exposed to cigarette smoke only or to cocaine plus…

This book is a collection of 66 "How Things Work" columns from the journal "The Physics Teacher," 1983-1991. All the devices and phenomena are ones that are met in everyday life, involve physics principles, and require explanations that are not immediately obvious. Topics include: touch panels in elevators, liquid crystal…

Describes a full day of chemistry fun and competition for high school chemistry students. Notes teams have five students from each high school. Lists five competitive events for each team: titration, qualitative analysis, balancing equations, general chemistry quiz, and quantitative analysis with atomic absorption spectroscopy. (MVL)

Examines a solubility laboratory experiment using silver acetate and spectrophotometers for an Advanced Placement chemistry course. Covers experimental procedure, analysis of saturated solutions, and a discussion of chemistry involved. Includes an absorbance curve for silver ions and solution preparation suggestions. (ML)

Discusses process analytical chemistry as a discipline designed to supply quantitative and qualitative information about a chemical process. Encourages academic institutions to examine this field for employment opportunities for students. Describes the five areas of process analytical chemistry, including off-line, at-line, on-line, in-line, and…

Describes a personalized method of instruction being used in junior-level physical chemistry classes which uses computer-aided instruction (CAI) and computer-managed instruction (CMI). Claims this results in more instructor-student interaction, better use of classroom time, and better scores on standardized examinations. (TW)

Presents five computer programs: (1) Accurate Numerical Solutions of the One-Dimensional Schrodinger Equation; (2) NMR Simulation and Interactive Drill/Interpretation; (3) A Simple Computer Program for the Calculation of 13C-NMR Chemical Shifts; (4) Constants of 1:1 Complexes from NMR or Spectrophotometric Measurements; and (5) Saturation…

This concept module on radiation is one of thirteen modules that provide a flexible, laboratory-based physics instructional package designed to meet the specialized needs of students in two-year, postsecondary technical schools. Each of the thirteen concept modules discusses a single physics concept and how it is applied to each energy system.…

Contains seven articles about computer applications to chemistry instruction. Includes descriptions of a three-dimensional animation of a potential energy surface, numerical solutions of kinetic equations, applications for spectroscopy courses, a computer-controlled experiment on the tin/lead solid/liquid phase diagram, an inexpensive thermistor…

Describes eight uses of the microcomputer in the chemistry classroom. Includes games, simulations, and graphics programs most of which are available from Project SERAPHIM. (MVL)

Thirty-two computer-based lesson modules in organic chemistry were developed at the University of Texas (Austin) over an 18-month period and evaluated in varying classroom situations for three semesters starting in the Fall of 1972. The modules were designed as supplements to the traditional organic chemistry course of the University. As such,…

For as long as people have walked the Earth, they have looked to the stars, have been inspired by their beauty and remoteness and have found their way over sea and deserts by their guidance. Since then, enormous progress has been made in the understanding of the stars, and today the expanding and fascinating world of high-energy astronomy awaits…

As part of the National Aeronautics and Space Administration Mission to Planet Earth, ATLAS 2 will help develop a thorough picture of the Sun's output, its interaction with the atmosphere, and the well-being of Earth's middle atmosphere. This middle school level guide probes the connection between the activities of scientists and the observable…
