Describes an experiment combining qualitative and quantitative information from hydrogen nuclear magnetic resonance spectra. Reviews theory, discusses the experimental approach, and provides sample results. (JM)

A general laboratory course should include projects that familiarize college students with the variety of methods available to the researcher. Described are four research projects that address questions about human behavior by means of experimental, observational, survey, and archival research methods. (RM)

Described is a diffusion apparatus to be used in an undergraduate physical chemistry laboratory experiment to determine the diffusion coefficients of aqueous solutions of sucrose and potassium dichromate. Included is the principle of the method, apparatus design and description, and experimental procedure. (Author/DS)

This paper describes the Scientific Tools and Techniques course for ninth grade students in the Dekalb County, Georgia, public high schools. The course is offered at the Fernbank Science Center, a magnet school owned by the Dekalb County Schools and Fernbank Incorporated and operated by the school system. Investigations are described in the…

Student-designed laboratory exercises have become an important part of the physics classes at Piedmont Virginia Community College. Rather than filling in the blanks of a laboratory workbook, students are required to design and carry out weekly experiments which relate to the physics concepts being studied. Using computers, standard laboratory…

Describes a method of flow injection analysis intended for calculation of complex-formation and redox reaction stoichiometries based on a closed-loop configuration. The technique is suitable for use in undergraduate laboratories. Information is provided for equipment, materials, procedures, and sample results. (JM)

Described is an experiment used in an undergraduate biochemistry laboratory involving inducing rickets in chicks and correlating the disease to a reduction in vitamin D-dependent calcium binding protein. Techniques involved are hormone induction, protein isolation, and radioisotope methodology. (Author/DS)

Described is an experiment designed to provide an experimental basis for a unifying point of view (utilizing theoretical framework and chemistry laboratory experiments) for physical chemistry students. Three experiments are described: phase equilibrium, chemical equilibrium, and a test of the third law of thermodynamics. (Author/DS)

Expresses concern over recent actions by coalitions of neighborhood activists and animal rightists in the San Francisco area that are seeking to block new biology laboratories. Argues that costly delays and disurption of research could result. (TW)

Addresses whether or not science laboratory activities should become a thing of the past. Discusses the impact of the curriculum reforms of the 1960s and 1970s, physical restraints which cause teacher overload, rationale, and objectives of laboratory work. (RT)

Describes a year long laboratory program for third, fourth, and fifth graders. States the goal of the program is to demonstrate what chemistry is, how it is done, and why it is fun and interesting. Provides a syllabus of the experiments and lists educational objectives. (MVL)

Examines some of the considerations involved in setting up a typical oxygen/organic reaction. These considerations (including protection for personnel/equipment, adequate ventilation, reactor design, maximum reactor charge, operating procedures, and others) influence how the reaction is to be conducted and what compromises the scientist must…

Smaller amounts of materials are used in organic chemistry experiments as a means of improving air quality in the laboratory. Presents a preliminary study of the emissions from selected processes and the mixing of these emissions within the laboratory atmosphere. (JN)

This selected collection of How-To-Do-It articles published in the American Biology Teacher during the past six years presents experiments that can be conducted safely under properly trained and responsible teacher supervision. Contents include: (1) "General Biology and the Nature of Science"; (2) "Cells and Molecules"; (3) "Microbes and Fungi";…
