The use of computer spreadsheet programs in the physics laboratory is discussed. An example of this application with a conservation of energy laboratory is presented including the cases of a rolling sphere and a sliding sphere. (CW)

Two designs of undergraduate terrestrial ecology and behavior field courses are described and compared. These include using a variety of projects and using a single individual research project. The relative educational benefits of each are considered and the advantages of each type of course are discussed. (Author/CW)

Described is a field trip for high school and college students to the country of Belize to study tropical ecology. Discussed are planning and special considerations. Included are a sample schedule and a planning guide. (CW)

Presented is an overview of the status of robotics education with information about activities and curricula for several European institutions. Some thoughts concerning the structure of a separate robotics curriculum at the university level are included. (Author/YP)

Presented is an experiment which can be used in a first-year chemistry class to introduce the synthesis and analysis of compounds. Described are the experimental procedures, sample data, analysis, and discussion. (CW)

Proposed are preparation methods of the active and inactive forms of Cosalen. An experiment of heterogeneous kinetics that consists of following the time dependence of the oxygenation of the active solid and measuring the oxygenation capacity of the chelate is described. (CW)

Described is a case, a heterocyclic sulfoxide, which is useful for an introduction to first-order four-spin data analysis. Background of this technique for use with undergraduate students is given including a sample analysis, a list of supplementary materials, and experimental procedures. (CW)

Procedures for safely identifying, preparing and consuming edible plants in the outdoors are provided. Listed are edible plants, references, sources of recipes, nutrient content, and toxic plants. (CW)

The evolution of ideas about the concept of chaos is surveyed. Discussed are chaos in deterministic, dynamic systems; order in dissipative systems; and thermodynamics and irreversibility. Included are logistic and bifurcation maps to illustrate points made in the discussion. (CW)

Presents a review of research focusing on scattering, elution techniques, electrozone sensing, filtration, centrifugation, comparison of techniques, data analysis, and particle size standards. The review covers the period 1986-1988. (MVL)

This review is divided into the following analytical methods: ion spectroscopy, electron spectroscopy, scanning tunneling microscopy, atomic force microscopy, optical spectroscopy, desorption techniques, and X-ray techniques. (MVL)

Discusses the problem of symmetry avoidance using water as an historical example. Uses simple pi systems for the analysis. Provides methodology and examples. Investigates two naive arguments. (MVL)

Presents a laboratory experiment which illustrates the formation of tris(phenanthroline)cobalt complexes in the 2+ and 3+ oxidation states, the effect of coordination on reactions of the ligand, and the use of a ligand displacement reaction in recovering the transformed ligand. Uses IR, UV-VIS, conductivity, and NMR. (MVL)

Presents a short reaction sequence that allows the student to determine by spectroscopic methods the constitution and stereochemistry of the reaction products. Reports the interpretations needed to illustrate the usefulness of the spectroscopic method. Notes the products of the Michael-Aldol reaction have not been reported in the literature. (MVL)

Responses from six engineering professors to a previous article about teaching engineering ethics are presented. Programs at several schools are described. The need to teach ethics to engineering students is reinforced. (CW)
