Outlines a variety of laboratory procedures, demonstrations, and classroom materials including a three dimensional, moveable cardboard model of the rib cage and diaphragm; a polyphenal oxidase experiment; ringing experiment using Impatiens; enzyme rummy game; and leaf impressions. (DS)

Suggestions are given for encouraging parents to participate in their children's science studies, at home and at school. Several sample lessons illustrate the kinds of experiments that require only inexpensive supplies which parents can provide. (SA)

A laboratory course designed to provide simulated practice experience for pharmacy students at Drake University College of Pharmacy was redesigned by restructuring laboratory schedules to provide more time, by establishing competencies to be attained, and by self-pacing. Student evaluations of the changes were highly supportive. (MSE)

Describes an experimental setup which allows the student to investigate the resonance characteristics of a vibrating plate using a small, circular steel plate clamped around its perpiphery. (HM)

Described are laboratory methods for enumerating microorganisms in food. These methods are utilized to determine if foods are potentially hazardous to the consumer due to high concentrations of microorganisms. Discussed are indicator organisms, including coliforms, interococci, yeasts, and molds; food poisoning organisms (staphylococci and…

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)

Reports on an experiment that sought to determine the change in attitudes of secondary school students toward Mexico and Mexicans following a five-week experience in Mexico. Attitudes were tested on a semantic differential. (AM)

The history of the curriculum, faculty, and facilities for veterinary anatomy at Auburn University is presented. Since its beginning in 1892, the program has expanded. A reduction in anatomical contact hours in the professional curriculum is viewed as a reflection of improved teaching methods and expansion of veterinary knowledge. (BH)

The use of a laboratory demonstration and discussion period in physiology and pharmacology instruction at the Univeristy of Tennessee College of Veterinary Medicine is described. The advantages for instruction include lower costs, fewer personnel and animals required, less time required in the curriculum, and increased student attention in class.…

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)

The use of live animals in the secondary school laboratory is discussed along with suggestions for increasing the use of live animals and challenges to those teachers who restrict this use. (SA)

Ball State University has developed a diverse offering of courses available by interactive television as one way to increase access to higher education and provide lifelong learning opportunities. Explains how to develop a general studies biology course for interactive television. Topics include course formats, course design, copyright issues, the…

Describes a primarily volunteer project that was developed with private industry to contribute to the research on space-grown vegetables and to promote science as a career. Focuses on the effects of microgravity and space travel on the germination and growth of plants. (DDR)

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…
