Discusses and suggests some solutions for three problems related to chemistry laboratory management, including disappearance of teaching assistants, check in/out procedures, and slow students. (YP)

This handbook is based on a list of essential topics that should be mastered by the student who subsequently plans to pursue college chemistry. Chapters include: (1) "Introduction" (describing a position paper and the background of the handbook); (2) "Essential General Topics and Objectives"; (3) "Testing Students"…

Describes a semester-long project in which students designed, built, and operated an apparatus to separate particles by fluidization principles. Each laboratory group worked on a separate step of the design in a sequence selected by the instructor in a manner similar to the way a design team might function. (JN)

Describes a drying experiment useful in presenting the concept of simultaneous heat and mass transfer. Background information, equipment requirements, experimental procedures, and results are provided. The reasonably good agreement in the calculated rate of drying and that observed experimentally makes students feel confident in applying…

Describes an experiment demonstrating Lenz's law by measuring a magnet falling through a copper tube compared to a nonmagnet falling. Presents diagrams and pictures showing the apparatus. (YP)

Indicates that the most dangerous laboratory hazards are the least dramatic ones and that hazardous chemicals are often used in laboratories without proper precautions. Selected sources of information essential for secondary schools and recommendations for safe practices and chemical use statistics from a study of Ohio high schools are given. (DH)

Described is a demonstration science laboratory at the University of Florida. Discussed is laboratory design, including instructional space, lab stations, sink areas, safety areas, and a storage and distribution area. The impact of this type of design is cited. Diagrams and photographs are included. (CW)

Described is a laboratory procedure which uses the small intestines of mice as models for the transport of glucose and other solutes. Demonstrations are suitable for either introductory or advanced physiology courses. (RE)

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)

Discussed are the potential hazards associated with nitric acid, inorganic and organic nitrate salts, alkyl nitrates, acyl nitrates, aliphatic nitro compounds, aromatic nitro compounds, and nitration reactions. (CW)

Describes some experiments for investigating the speed of atomic gas beams and displaying their atomic character. Discusses the experimental apparatus and the time-of-flight method. (YP)

This manual was written as an aid to teaching assistants (TAs) who conduct the laboratory portions of life science courses at the University of Washington. In general, this manual does not present specific factual material. Rather, it offers suggestions on how to handle various teaching situations and provides a framework to use in many different…

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)

Provides the apparatus setup, experimental method, necessary formulas, and references for three measurement experiments: (1) "Determine the Magnetic Induction of a Coil with a Hall Element"; (2) "Measuring Magnetic Force and Magnetic Field of Small Permanent Magnets"; and (3) "Measurements of Sound Velocity by Means of PZT" (piezoelectric…

Discussed are accidents that occur in the laboratories of highly trained chemists. Four examples are provided to illustrate potential hazards that are often overlooked in chemistry laboratories, molten inorganic salt baths, the reaction of acetone and hydrogen peroxide, halogenated acetylene compounds, and the reaction of hydrogen peroxide and…
