The development of the "Science Career Predictor Scale" instrument using samples of middle school, high school and college students is discussed. Investigations of attitudes toward science, critical thinking ability, and participation in college science programs are highlighted. A list of 128 references is included. (CW)

Presented is an analysis of think-aloud protocols of graduate students solving several different tasks in organic chemistry. The systems used by these subjects were classified. It was reported that the methodological system was most often used. (CW)

Described is a survey of firms which hire biologists. Summarized are required knowledge, skills, qualifications, and attributes required of candidates; types of jobs being filled; and methods of finding qualified candidates. Careers in biotechnology areas are highlighted. (CW)

Discussed are the uses of sea urchins in research and their usefulness and advantages in the classroom investigation of embryology. Ideas for classroom activities and student research are presented. Lists 25 references. (CW)

Described is an activity in which the transmission of disease is simulated by the students in the classroom using common solutions. Discussed are materials, preparation, procedures, and questions for classroom discussion. (CW)

Presented are two demonstrations including a variation of the iodine clock reaction, and a simple demonstration of refractive index. The materials, procedures, and a discussion of probable results are given for each. (CW)

Described is an experiment which illustrates valence isomerization, the trapping of a reactive intermediate and retrosynthetic analysis applied to the Diels-Alder reaction. Included is a background discussion, experimental procedures, and a discussion of the analysis. (CW)

A laboratory experiment designed as a model for studying enzyme activity with a basic spectrometer is presented. Included are background information, experimental procedures, and a discussion of probable results. Stressed is the value of the use of Nuclear Magnetic Resonance in biochemistry. (CW)

Claims scientific literacy is important for all college students, including nonscience majors. Discusses issues related to scientific literacy and courses that include scientific literacy. (YP)

Presented is a strategy which uses creationism and other pseudosciences as examples of non-scientific approaches to critical thinking to teach students the nature of science and the scientific method. Examples of the illogic of non-scientific approaches are given along with an explanation of how they can be used in teaching critical thinking to…

Described is an apparatus which can be made for student use in performing organic qualitative analysis. The flask replaces the need for more expensive equipment. Discussed are reagents, equipment preparation, experimental procedures, and sample preparation. (CW)

Two exercises on the dispersal of tree seeds by the wind are presented. Procedures, equipment, and analysis for the still air and wind dispersal activities are described. Nineteen references are listed. (CW)

The construction of a wooden model of the musculoskeletal system which can be used to investigate the physical properties of muscles without sacrificing laboratory animals is presented. Six activities are included with answers. Additional activities are suggested. (CW)

Described is a procedure by which the performance of chemical hoods can be tested. This procedure uses a mixture of dry ice and water to create a "smoke" for use in the test. Implications for sash design, performance evaluations and testing under standard and nonstandard conditions are discussed. (CW)

Discussed is a technique used by Alfred Werner to resolve inorganic coordination compounds. The materials, procedures and analysis necessary for undergraduates to repeat this procedure are described. (CW)
