Described are three chemistry demonstrations: (1) a simple qualitative technique for taste pattern recognition in structure-activity relationships; (2) a microscale study of gaseous diffusion using bleach, HCl, ammonia, and phenolphthalein; and (3) the rotation of polarized light by stereoisomers of limonene. (MVL)

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 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,…

Methods use to reconstruct traffic accidents provide settings for real life applications for students in precalculus, mathematical analysis, or trigonometry. Described is the investigation of an accident in conjunction with the local Highway Patrol Academy integrating physics, vector, and trigonometry. Class findings were compared with those of…

Describes a computer simulation of the Compton effect designed to lead students to discover (1) the relationship of the electron's final kinetic energy to its angle of scattering and (2) the relationship between the scattering angles of the outgoing electron and photon. (MDH)

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,…

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…

Describes an extra credit science project in which students compete to see who can build the most efficient water rocket out of a two-liter pop bottle. Provides instructions on how to build a demonstration rocket and launching pad. (MDH)

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…

Proposes engaging low achievers in science activities that appeal to their interests. Describes an example involving fishing that explores scientific concepts related to the search for bait, the fishing equipment, the use of solunar tables to determine the best time to go, processing the catch, and survival tips for the trip. (MDH)

Presents an annotated bibliography listed under the following categories: (1) Animals; (2) Archaeology, Anthropology, and Paleontology; (3) Biography; (4) Environment and Conservation; (5) Nature and Life; (6) Physics, Technology, and Engineering; and (7) Underwater and Outer Space. Selection criteria are given. (MDH)

Addresses problems with mathematics and science curricula at both elementary and secondary levels, and calls for helping more students succeed at the physics level of the science curriculum. (PVD)

Describes some adaptations made in a university physics laboratory course to accommodate a student with total visual impairment. (WRM)

Used the lesson preparation method and interviews to investigate preservice physics teachers' pedagogical content knowledge, focusing on their knowledge of pupils' conceptual difficulties with temperature and heat. Results found a relationship between conceptual difficulties preservice teachers expected their pupils to have and conceptual…

This instructional design blends a structured learning environment (the physics lesson) with an engaging, playful, simulated environment (roller coaster construction), putting into operation ideas from both cognitive and constructivist theories. Two instructional models are used: a general design model for creating instruction and a lesson design…
