A National Research Council report has recommended practices for safe handling and disposal of hazardous chemicals in laboratories. They are a practical alternative to detailed regulations on individual chemicals. Topics discussed include physical hazards, chemical hazards, chronic hazards, laboratory ventalation, protective equipment,…

Summarizes a theoretical approach using nonbonding MO's and perturbation theory to correlate properties of saturated hydrocarbons. Discussion is limited to correctly predicted using this method. Suggests calculations can be carried out quickly in organic chemistry. (Author/SA)

Describes the status of teaching physics at Xaverian High School, Brooklyn, New York. The enrollment of students in physics, instructional materials, laboratory activities, and coordination between physics and mathematics are described. (HM)

Opportunities for high school students and adults to take courses in aviation education as part of the science curriculum in Wichita, Kansas, are described. (Author/SA)

Describes laboratory experiments of a chemistry course on advanced process control. The equipment for the process around which these experiments were developed by the University of Louisville was constructed from data provided by Exxon Oil Company. (HM)

Investigated were the science attitudes of preservice elementary teachers when "professionally related activities" were incorporated into a science laboratory course for elementary education majors. (Author/SA)

The results of testing a theoretical model for laboratory psychomotor skill development are described. Research implications for fine motor learning in the chemistry laboratory are given. (Author/SA)

Ideas related to including ethology in high school biology programs are given. The methods of ethology and tips on how to communicate observations are briefly explained. (SA)

This paper, presented at the conference on the role of the laboratory in physics education which was held in Oxford, England in July 1978, describes how a Malaysian University has presented electronics and the laboratory work as a forced component in physics curriculum. (HM)

A description of an apparatus for demonstrating the trajectory of a charged particle, is given. A photograph of the equipment used in the demonstrations accompanies the text. (SA)

The heating, ventilating, and air conditioning (HVAC) systems in older buildings often do not adequately handle air-borne contaminants. Outlines a three-stage Indoor Air Quality (IAQ) assessment and describes a case in point at a Pittsburgh, Pennsylvania, school. (MLF)

Discussed are the deficiencies of teaching laboratories in science education and the feasibility study and development of the Institute for Teaching Experimental Chemistry at Carnegie Mellon University. The primary goals of the program and its significant elements are presented. (CW)

Discusses a high school advanced placement physics course cooperating with neighboring college. Describes the background, titles of experiments, report format, and discussion. (YP)

Provides information on the parts, materials, prices, dimensions, and tools needed for the construction of a telescope that can be used in high school science laboratories. Includes step-by-step directions and a diagram for assembly. (RT)

Presents an overview of coatings along with paint preparation labs. Provides students with information about and methods for preparing a product that is an integral part of daily life. Gives methodology which can be used to prepare oil based and water based paints. (MVL)
