Discusses the generation, collection, and disposal of hazardous and other wastes in the chemistry laboratory. Offers suggestions related to these three areas to provide a safe teaching environment, including minimizing amounts of reagents used (and potentially wasted) by scaling down experiments. (JN)

Provides list of tests available for the 1983 American Chemical Society (ACE) testing program and tables of condensed norms for six ACE examinations. Also provides a listing of the subject matter content of General Chemistry Form 1983 and 1983B. The test contains 80 items in 15 major areas. (JN)

Discusses marine adaptations of seabirds, feeding/breeding methods, and their vulnerability to predators. Also considers dangers from new "predators," such as hunting, environmental factors (pollution/pesticides), and loss of natural environments. Future prospects for the survival of these organisms are considered. (JN)

United States scientists are being pressured by the government to cut back on scientific exchanges with the Soviet Union for both "natural security" and political reasons. Various aspects of the issue are discussed, suggesting that science itself will be the big loser in the government's shift of attitude toward science communication.…

Suggests stressing the humanistic dimensions of science as a way to bridge the gap between sciences and the humanities. Provides a rationale for focusing on the humanistic side of science and briefly describes a freshman seminar at Macalester College (St. Paul, Minn.) conducted by science, social science, and humanities faculty. (JN)

Describes computer grading system providing/storing scores and giving feedback to instructors on how students are performing on a day-to-day basis and how they are handling course concepts. Focuses on the hardware and software of this efficient computerized grading package, which can be used with classes of 250 students (or larger). (Author/JN)

A college level plasmolysis experiment, demonstrating principles of cell/water relations, has been modified to demonstrate the objective collection of data. Background information, laboratory procedures, results, and instructional strategies are provided. (Author/JN)

Highlights geological history activities during 1982. These include formation of The History of Earth Sciences Societies, publication of a new journal ("Earth Sciences History: The Journal of the History of Earth Sciences Societies"), and presentation of the first history of geology award. Comments on geological history publications are…

Mathematical techniques used to solve geological problems are briefly discussed (including comments on use of geostatistics). Highlights of conferences/meetings and conference papers in mathematical geology are also provided. (JN)

Provides a discussion of and instructions for preparing an efficient observation log to fit the personal interests and needs of the observer. A sample log for observing weather-related phenomena is included. (JN)

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)
