Discusses distillation of liquid mixtures with the emphasis on experimental work. A number of experiments, intended for chemistry secondary school teachers in the United Kingdom, are included. (HM)

Describes an experiment which makes use of a number of concepts from geometrical optics. The apparatus and method which is intended for students in elementary college physics classes are included. (HM)

Describes a student field project involving the estimation of a maximum rate of erosion for a local area. Identifies the factors influencing erosion and outlines the method of investigation. (GS)

Outlines steps to follow and recommends special features when selecting equipment for an engineering computer graphics laboratory. Expansion features are also discussed. Provides a systems checklist for software and hardware. (CS)

Provides information regarding spill control systems in chemical and biological laboratories. Various methods currently in use are described. Suggestions are made for the use of absorbents. (CS)

Describes a university-wide program directed at reducing the improper storage and disposal of toxic chemical wastes from laboratories. Specific information is included on the implementation of a waste pick-up service, safety equipment, materials and methods for packaging, and costs of the program. (CS)

Described is a "joke center" where elementary school students not only learned about various kinds of humor and practiced language skills but had a terrific week of laughter as they shared favorite jokes and made up new ones. (Author/KC)

Reviews materials from the ERIC database describing the variety of functions a high school reading lab can perform and suggesting ways to evaluate student improvement in the reading lab situation. (MKM)

Described is an apparatus for determining the Curie temperature of a Ferromagnetic material which enables large specimens to be heated up to a maximum of 1100K in 20 minutes. Included is the theory, magnetic circuit apparatus, electrical circuit, and results using this apparatus. (DS)

Presents and explains analytical procedures for the detection and quantitative enumeration of bacteria which constitute or are indicators of fecal contamination of aquatic environments. Tests are given for Escherichia coli, fecal Streptococci, Clostridium perfringens, and Salmonella. (WB)

Describes urinalysis techniques for dry weight measurement, examination of urinary calculi (stones), and determination of the presence of blood and blood pigments. Also presented are directions for preparing required reagents. (WB)

To determine if an association exists between research methods and findings in attitude-behavior research, a review of the literature was conducted. More laboratory studies reported a positive relationship between attitudes and behavior, while more field studies found no such relationship. Extensive bibliography included. (Author)

Describes a prelab activity, the chemistry report, that acquaints college students with the nature of the chemical(s) they are using in the laboratory. Methodology, experimental procedures and safety rules are emphasized, with particular emphasis on potential hazards, safety requirements and emergency procedures. (CS)

Outlines a procedure where chromatographic separation can be easily done and provides an introduction to column chromatography. (CS)

Presents a checklist developed to help chemistry teachers assess conditions in the storeroom. The checklist format facilitates a systematic assessment of storage conditions and serves as a record of where improvements are needed. Also lists classes of chemicals requiring special storage precautions. (Author/SK)
