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…

Describes techniques for studying hand specimens of polished rock slabs. (SL)

The laboratory approach to science and mathematics is described as a refreshing change for both teacher and students. Suggestions are given for planning a laboratory-based program. Guidelines for teachers of both handicapped and non handicapped are included. A school for handicapped children in Minneapolis is described. (EB)

Describes an attempt to develop and staff a new first-year laboratory course at the University of Jordan. A postgraduate course in chemical education is used as the development and training vehicle. (BT)

Describes a final year undergraduate course in which students use X-ray diffraction to identify clay minerals. (SL)

This inexpensive but informative experiment for undergraduate biochemistry students involves isolating phosphatidyl choline from spinach leaves. Emphasis is on introducing students to techniques of lipid extraction, separation of lipids, identification using thin layer chromatography, and identification of fatty acids. Three periods of three hours…

Presents some introductory experiments involving the reaction between EDTA and several metal ions using metallochromic indicators. The experiments represent familiar reactions and are followed by suggestions for extension into areas of discovery work by students. (Author/SA)

Describes a laboratory safety program at the University of Delaware. Includes a history of the program's development, along with standard safety training and inspections now being implemented. Outlines a two-day laboratory safety course given to all graduate students and staff in chemical engineering. (TW)
