Describes an undergraduate research program for minority students. The program and eight objectives of the first course of the program, "Introduction to Research," are presented. Some strengths and weaknesses of the course are considered. (YP)

Describes several experiments using the techniques of thermal analysis and thermometric titrimetry. Defines thermal analysis and several recent branches of the technique. Notes most of the experiments use simple equipment and standard laboratory techniques. (MVL)

Reviews the current goals of a laboratory course and describes experiences in using laboratory time to cover several important topics related to industry and academia. Discusses several subjects and presents related experiments. Contains 184 references. (DDR)

Describes an experiment in which acetaminophen is converted into phenacetin, that has been used at Shepherd College in an introductory chemistry course for nurses and in the organic chemistry laboratory. (BT)

A discussion is given of the ways in which thermal conductivity, velocity, and viscosity of sound propagation of gases can be measured by freshmen college students. (Author/SA)

Presents a low cost system with easily replaced electrodes for use in general chemistry. Notes the accuracy and wide applicability permit easy use in physical or quantitative chemistry experiments. Provides schematic, theory, and helpful suggestions. (MVL)

Provides methodology for carrying out the synthesis of sec-butyltoluene by the Friedel-Crafts alkylation of toluene. Suggests using simple elemental aluminum as the catalyst in place of AlCl3 or amalgamated aluminum. Notes satisfactory results for both macro- and microscale operations. (MVL)

Notes that laboratory work should be more oriented towards puzzle solving rather than technique or illustration. Offers three organic laboratory puzzles which can be solved by melting point alone. Involves lab work at the 100-200-mg scale but still uses conventional glassware. (MVL)

Notes that this experiment takes safety and noncarcinogenic reactants into account. Demonstrates the use of diazonium salts for the replacement of an aromatic amine group by a phenolic hydroxyl. Involves two pleasant-smelling organic compounds, methyl anthranilate (grape) and methyl salicylate (oil of wintergreen). (MVL)

Reports an experimental procedure for studying Einstein's theory of Brownian movement using commercially available latex microspheres and a video camera. Describes how students can monitor sphere motions and determine Avogadro's number. Uses a black and white video camera, microscope, and TV. (ML)

Discusses role of computer simulation in complementing and extending conventional components of undergraduate engineering education process in United Kingdom universities and polytechnics. Aspects of computer-based learning are reviewed (laboratory simulation, lecture and tutorial support, inservice teacher education) with reference to programs in…

Provides a first experiment for college chemistry that provides insights into scientific procedures without presupposing any detailed knowledge of chemistry on the part of the student. Requires the student to measure successive masses and volumes and use these values to determine the density from the slope of the graph. (MVL)

Presents relevant statistics accumulated in a fall organic laboratory course. Discusses laboratory equipment setup to lower the amount of waste. Notes decreased solid wastes were produced compared to the previous semester. (MVL)

Describes an experimental procedure for determining trihalomethanes (THMs) in liquids by gas chromatography. Provides recommendations for reactants and supplies to obtain acceptable results. Discusses the analysis of water from various sources: pools, lakes, and drinking water; compares these to three cola drinks. (ML)

Describes a number of student-focused laboratory exercises that are inexpensive, yet show the scientific character of archaeology. Describes the environmental laboratory exercise which includes the following analysis topics: (1) pollen; (2) earth core; (3) microfaunal; and (4) microwear. Describes the ceramic laboratory which involves…
