Experiments designed to help undergraduate students gain experience operating instruments and interpreting gas chromatography and mass spectrometry data are presented. Experimental reagents, procedures, analysis, and probable results are discussed. (CW)

Discussed are the procedures and results involved in this activity. Student results in undergraduate laboratories indicate high quality results and relative ease of the analysis. (CW)

The status and experiences of women in science and engineering are discussed. Specifically highlighted is the situation at Hood College, Maryland, a school with a majority of female students. Strategies for encouraging female students to enter and continue in science majors and careers are suggested. (CW)

Described is an extracurricular program for high school students in which they visited a college physics laboratory facility and participated in laboratory activities. Discussed are the planning, student experiences, and results. (CW)

Described are instructional experiences with the use of homemade videofilms. Two particular techniques that can be useful in the production of these films are discussed including the use of chromakey and split-screen. (CW)

Presented are three physics problems from the New Zealand Entrance Scholarship examinations which are generally attempted by more able students. Problem situations, illustrations, and solutions are detailed. (CW)

A demonstration which illustrates the concept of electric potential using electrophorous is presented. Equipment and procedures for the demonstration are discussed. (CW)

Reported is a study designed to improve problem-solving skills of high school chemistry students. Interpretations of the data are presented. Recommendations for improvement in teaching problem solving in chemistry are proposed. (CW)

Compared in this research was the performance of students on numerical versus conceptual chemistry problems at the introductory college level. Separate analyses were done to compare high and low achievers. It was shown that even the upper group of achievers had difficulty with concept questions. (CW)

Described is a technique for fiber identification for use by K-6 students. Follow-up activities for elementary and college students are suggested. (CW)

Described are the apparatus and procedures needed for a demonstration of variables which affect centripetal force. Discussed are materials, apparatus construction, calibration, and experimental results. (CW)

Findings from a survey of 20 liberal arts colleges which did not have graduate programs in chemistry are presented. Discussed are regulations, actions taken and costs of academic laboratories regarding the disposal of hazardous waste. (CW)

Proposed is a more didactic version of the electronic periodic table than is being used. The background and use of the numeric system is detailed and illustrated. (CW)

Reviewed are 15 methods for fast slide production. Methods are classified as in-hand methods and farmed-out methods of slide production. Slides are compared to transparencies as another fast presentation aid. (CW)

Three demonstrations (a mechanical model of chemical equilibrium, a demonstration of Raoult's Law, and a demonstration of permanganate reduction) are presented. Materials and procedures are detailed. (CW)
