Described is a course which combines the usual instruction in technical subjects of industrial chemical operations with some of the business aspects that compose the total commercial enterprise. The two-hour-a-week semester course syllabus is provided. A business game to develop a plan for business expansion is included. (MVL)

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)

Describes how to make the following paper molecular models: trigonal prism; tetragonal pyramid; tetrahedral; and trigonal pyramid. Methodology is given for general paper model manipulation to make various shapes including a chain of tetrahedra and an icosahedron. (MVL)

Reviews three chemistry software programs at the high school and college general chemistry level for the Apple II family. Includes "Chemical Nomenclature and Balancing Equations,""Principles of Stoichiometry," and "Solubility." (MVL)

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)

Discussed are problems encountered when a gas absorption experiment with strong measurement error is used. Notes students either avoid the experiment or report it as defective. Provides ideas to make lab experiments more instructive. (MVL)

Reviews three computer software programs: (1) "Discovery! Experiences with Scientific Reasoning"--problem solving for grades 4-12 (Apple II); (2) "Organic Stereochemistry"--a tutorial for organic chemistry for advanced secondary/college level (Apple II); and (3) "SHOW PARTNER (2.01)"--a graphics utility tool for…

Presents a qualitative view of the science classes of a high school teacher that had been judged exemplary before the study. Reports on the nature of classroom learning and interactions, and contextual factors. Includes the teacher's reactions to observations of the classroom. Concludes that fundamental changes are necessary to improve science…

Discusses how, in two three-week sessions, the Terre Haute (Indiana) college offers selected students a hands-on approach to all aspects of engineering from design and lab work to technical writing. Describes a group project requiring students to study and experiment with simple research problems. Lists 20 project ideas. (MVL)

A national survey of 123 heads/coordinators of first-year chemistry in state colleges and universities reveals that what high school chemistry teachers think the college professor looks for in a first-year chemistry student may be inconsistent with professor's true expectations. The results are used to suggest that chemistry teachers and college…

A study in which nonscience professors and graduate students took introductory physics and chemistry courses and found that what makes science unappealing or difficult for some is not subject matter or lack of student preparedness but the way science is packaged. Problems with curriculum design, testing, grading, classroom climate, presentation,…

Presented are 25 science activities on colorations of prey, evolution, blood, physiology, nutrition, enzyme kinetics, leaf pigments, analytical chemistry, milk, proteins, fermentation, surface effects of liquids, magnetism, drug synthesis, solvents, wintergreen synthesis, chemical reactions, multicore cables, diffraction, air resistance,…

A study with 45 British undergraduate and graduate science students investigated the usefulness of a semistructured workshop interview to identify students' concept difficulties in chemistry, their understanding of the use of analog models, and other science education issues. Implications for use of the workshop interview technique are considered.…

In 1985, participants in the Second International Science Study developed and evaluated hands-on problem-solving activities and gave students the opportunity to demonstrate mastery of science process skills. Six evaluation stations for fifth and sixth graders are presented: Blowing in a Liquid, Compare and Contrast, Electrical Circuit, Hot and…

Twenty science experiments are presented. Topics include recombinant DNA, physiology, nucleophiles, reactivity series, molar volume of gases, spreadsheets in chemistry, hydrogen bonding, composite materials, radioactive decay, magnetism, speed, charged particles, compression waves, heat transfer, Ursa Major, balloons, current, and expansion of…
