A description is given of a chemically-oriented curriculum on "Smoking and Cigarette Smoke" for science and nonscience oriented high school students. Laboratory activity is emphasized. (SA)

Describes six laboratory procedures for preparing polymers which have been used in a course for undergraduate industrial arts students, who have a concentration in plastics technology but have not taken more than one year of college chemistry. (BT)

Describes several science activities designed around the upcoming Winter Olympics ice skating events which demonstrate the scientific principles behind the sport. Students learn that increasing the pressure on ice will lead to the ice melting, the principle involved in the spinning swing, and the technology of skates and skating outfits. (PVD)

Argues that with the increase in hands-on approaches to science, teachers are using more hazardous science demonstrations with less conceptual understanding than they should have. Poses questions for discussion within the chemical education community regarding the presentation of demonstration-based sessions at conferences. Stresses the…

Discussed are the two sides to the question of laboratory dissections. Alternatives to dissection are proposed as well as the importance of incorporating dissections in a science curriculum. (KR)

Reported is a profile of nonmajor instruction determined through a nationwide survey of college and university professors who teach introductory courses to non-science majors. The purpose of the survey was to identify the critical issues and problems that exist related to this population of students. (KR)

Reports on the teaching of recombinant DNA technology in high school biology courses. Explains reactions of the public, students, and colleagues to the molecular genetics unit. Indicates equipment, curricular materials, training, workshops, and availability. (RT)

Presents techniques used for disinfestation of plant material, preparation of equipment and media, and laboratory procedures for tissue culture using cauliflower. Details methods for preparing solutions and plant propagation by cloning. (CW)

The harmful effects of smoking tobacco are discussed. Instructions, lists of materials, and discussion questions for three activities to investigate these effects are provided. A glossary of tobacco-use terms is given. (CW)

Tests in each science area were developed around six laboratory tasks. Students had to plan an investigation, collect and organize data, and formulate conclusions based on calculations and graphs. Over 1,000 students from 32 Ohio schools formed the sample for this study. Data are presented by skill and by task. An analysis for gender and school…

With thousands of activities available, how does a teacher select activities appropriate for the classroom? Describes the guidelines of the "Science Activity Filter," which provide a useful protocol for evaluating science activities for their value in the classroom, allowing the teacher to use resources effectively, minimize discipline and safety…

Outlines 39 physics demonstrations that utilize simple objects such as coffee and soda cans to illustrate scientific concepts. (12 references) (MDH)

Proposes the V-Scope as a teaching aid to measure, analyze, and display three-dimensional multibody motion. Describes experiment setup considerations, how measurements are calculated, graphic representation capabilities, and modes of operation of this microcomputer-based system. (MDH)

Proposes methods by which laboratory practical exams may be structured to assess outcomes from laboratory instruction. Presents eight general considerations for writing and using practical exams. Describes four example laboratory exams involving a box camera, circuit boxes, floating objects, and light. (MDH)

Presents a class activity in which students use trigonometry to calculate the height attained by a water rocket. Provides a lesson plan that includes a list of materials needed, procedures to carry out the experiment, suggestions to extend the activity, and a reproducible worksheet for the students to register their calculations.
