Instructional strategies are described for a one-year program at the University of Washington which attempts to increase the number of minority students being admitted to health science professions. The strategies focus on the necessity of the laboratory, reasoning ability, examinations, and homework. (Author/SA)

Explains two approaches to the automatic arrest of a potentiometric titration. (SA)

Discusses safety matters in school and university chemistry laboratories and how to maintain clean, pollution-free air in the working areas in chemistry teaching and research laboratories. (HM)

Discusses the cognitive outcomes of physics laboratory exercises and suggests three types of experiments which should be added to those normally used in physics courses. (HM)

Describes a physics laboratory for college students, in which the students participate in a firsthand noninertial experience. The equipment and problems are described. (SA)

The hazards associated with recombinant DNA research are presented along with some social implications and the development of recombinant DNA research guidelines by the National Institutes of Health. (SA)

A programed, two-credit hour, experimental microbiology course for nonscience majors is described. (SA)

Catalysis is defined and discussed as the process relates to science history, chemical reactions, enzymes, industry, catalytic reactors, and catalyst preparation. (SA)

Presents a series of behavioral objectives for a 60 hour science unit designed to train laboratory technicians in safety, basic laboratory skills, laboratory service and fittings, and first aid. (SL)

Examines the benefits of the Z-shaped science lab classroom configuration as a means of learning enhancement. Each section of the classroom is illustrated and described. Also discusses construction and cost considerations. (GR)

Discusses the importance of laboratory safety in science classrooms. Urges middle school teachers to address class size in an effort to establish and maintain a safe working environment. Answers a teacher's question related to having newts and salamanders in the classroom. (SOE)

Describes portable scientific laboratories that allow students to go beyond the classroom to do field work. Presents examples of a curriculum that incorporates portable technology and discusses its advantages in inquiry-based science programs. Includes handheld probes and peripherals. (KHR)

Any overhead projector easily can be converted into a simple spectrometer by placing a piece of diffraction grating over the projecting lens. A detailed description of the apparatus and suggested spectroscopy experiments are included. Demonstrations can utilize solutions of cobalt chloride, potassium permanganate, potassium dichromate, or…

In this demonstration of the generation and combustion of acetylene, calcium carbide and water are allowed to react in a latex examination glove. Two student volunteers perform the demonstration with instructor guidance. This safe, popular demonstration, originally intended to illustrate the alkyne family of compounds, can be used with a variety…

Describes four models: The Authoring Cycle, a whole language approach that reflects the inquiry process; I-Search, an approach to research that uses the power of student interests; Cultural Celebration, using local heritage topics; and Science Lab Report, for the composition of a lab report. (LRW)
