Describes a team game in which a force table is used to solve vector problems, including rules and materials needed for the game. Ideas for other games in which physics topics can be used are also discussed, including a contest focusing on Project Physics Experiment 11, "Prediction of Trajectories." (JN)

The camera presents an excellent way to illustrate principles of geometrical optics. Basic camera optics of the single-lens reflex camera are discussed, including interchangeable lenses and accessories available to most owners. Several experiments are described and results compared with theoretical predictions or manufacturer specifications.…

Describes an apparatus used to demonstrate effects observed with polarized light. The apparatus employs two pendulums attached to threads crossing orthogonally over an overhead projector. Several demonstrations using the apparatus are provided. (Author/JN)

Describes construction of a model for observing a "green flash" (phenomenon witnessed under certain conditions just as the last bit of sun disappears below the horizon). Also describes an easily constructed, simple, three-dimensional vector arrow for instructional use. (JN)

Describes advantages of using longer focal-length concave and convex cylindrical mirrors constructed from sheets of flexible, back-surfaced, mirrored acrylic plastic. Suggestions for several student experiments, along with typical experimental results, are also presented. (Author/JN)

Although Newton's laws of motion are well known, studies have shown that many people have misconceptions about the motions of objects. Subjects of these studies tend to follow a theory held in the three centuries before Newton (impetus theory). This theory and studies examining misconceptions about motion are discussed. (JN)

Discusses the importance of teaching students when to seek deterministic explanations and when to seek probabilistic ones, pointing out that there are situations in which each is appropriate and inappropriate. Several examples illustrating the appropriateness of these explanations are provided. (JN)

Describes a chemistry course designed to meet needs of students who score well on Advanced Placement Chemistry examinations but who might experience difficulty if placed directly into a second-term course. The one-semester course includes substantially all work in Chemistry 1 and 2 (Rensselaer Polytechnic Institute) and features a flexible,…

Presents "Undergraduate Faculty Development in Science: A Report to the Congress by the National Science Foundation," recommending low priority for this program. Although two years old, the issues in the report are of paramount concern to planners charged with improving undergraduate science education. (Author/JN)

Determined whether or not formative evaluation could facilitate goal attainment in a biochemistry course and produce desired learning outcomes consistently by altering course materials and/or instruction. Formative evaluation procedures included two tests administered to subjects (N=64) over a three-year period. Findings supported the formative…

Discusses sources which provide information on data relating to physical properties of materials. Includes a list of seven organizations (six in Great Britain and one in Germany) providing such data. Includes problems in searching for information, suggesting that computer searches may solve some of the problems. (JN)

Discusses advantages of using computer-assisted instruction in a college general chemistry course. Advantages include using programs which generate random equations with double arrows (equilibrium systems) or generate alkane structural formula, asking for the correct IUPAC name of the structure. (Author/JN)

Provides criteria for evaluating microcomputer software. Categories include: (1) features/intent; (2) ease of use (documentation, operation, error handling, flexibility); (3) subject matter content; (4) pedagogic value; (5) student reaction; (6) recommendations for improvement; and (7) a summary section. (Author/JN)

A significant amount of scientific work is done in laboratories with limited ventilation capabilities. To operate at "acceptable risk", an understanding is needed of what ventilation systems can/cannot do. A simple experiment is described which assesses conditions under which specific experiments should be performed and serves to introduce…

Discusses a formal course designed to acquaint students with major sources of chemical information and with procedures for their efficient use. In addition, the place that such a course has in the chemistry curriculum is considered. (Author/JN)
