Describes a laboratory experiment which demonstrates manipulation of highly reactive chemicals, use of a gas trap, and simple and reduced pressure distillation. Student must characterize starting material and product with nuclear magnetic resonance and infrared spectroscopy. (Author/SA)

Presents information intended to encourage students to become thoughtful consumers. Discusses the role of pepsin in splitting off amino acids from stomach proteins and the nature of the protein substrate in determining the ph at which pepsin operates. Directions for an experiment are included. (Author/SA)

The study investigated specific student behavior in introductory and advanced college laboratories in botany, chemistry, geology, physics, and zoology. Behaviors were observed, described, and classified with no effort made to induce change, detail underlying conditions, or identify correlates. (Author/RE)

The use of pesticides in the schools is discussed. Some potential hazards include seeds dressed with fungicide/insecticide mixtures, fumigation of animal houses and greenhouses, and storage and disposal of pesticides. (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)

A demonstration is described that encourages students to engage in inquiry in biology. Using chemicals and an overhead projector, the instructor can simulate a living organism projected onto a screen. The reaction can aid students in defining the characteristics of life. (SA)

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)

Described is an advanced undergraduate laboratory experiment in which radio-frequency transitions between molecular hyperfine structure states may be observed. Aspects of the quantum theory applied to the analysis of this physical system, are discussed. (Authors/BT)

This experiment is intended as a classroom demonstration. It describes the preparation of materials, the procedure, and a few remarks related to demonstrating travelling waves of chemical activity in the Zaikin-Zhabotinskii-Winfree Reagent. (SA)

Organizing, storing, and using materials for classroom games are discussed. Materials and directions are listed for three strategy games, three whole number games, three fraction games, and three geometry games. (DT)

Explains the nature of a course on the biology of women which is part of a minor in women's studies. Provides the course objectives and a listing of all the courses required for the minor in women's studies. (DDR)

Describes a basic introductory chemistry experiment for science majors which departs from synthesis and moves instead into the realm of formulation. As part of a project that reorganizes the introductory chemistry sequence according to subjects with which students are acquainted, this laboratory makes use of oxidation-reduction chemistry to make…

Laboratory portions of courses in pharmacy practice and pharmaceutical analysis at the Medical University of South Carolina are integrated and coordinated to provide feedback on student performance in compounding medications. Students analyze the products they prepare, with early exposure to compendia requirements and other references. Student…

Recommends a constructivist approach to physics laboratory activities to make laboratories a place for personal maturation and cognitive growth. Describes class design in which ideas and techniques are exchanged which allow students the opportunity to initiate investigations based on early conceptual assumptions, and extend the investigation…

States that the ethics of using animals in science should be debated; however, the history of medicine is so clear on the contribution of animal usage to our understanding of the causes, preventions, and cures of diseases that only the untutored or those with a hidden agenda could argue that animal research has not been fundamental to medical…
