Presented is an activity that may be used to help students clarify the basics of graphing while allowing individuals to collect data and perform a simple experiment. A timetable, rules for graphing, materials, procedures, and suggestions for extension activities are provided. (CW)

Described are some of the considerations necessary in planning a field studies course in the tropics. Discussed are site selection; planning and preparation; course structure; the advantages of travel courses; and recommendations concerning liability, multiple instructors, hotels, sailboats, and tours. A list of 26 references is included. (CW)

A program was developed to ensure that teacher and institutional self-evaluation would become an integral part of staff development and curriculum development. A science curriculum module was taught to students with severe learning difficulties and videotaped for use in evaluation and inservice training. (JDD)

The integration of videodisc technology into the elementary school science classroom is discussed. Stressed are the restructuring of the classroom, creating a positive learning atmosphere, and extending the roles of the teacher and the student. A checklist for successfully integrating videodiscs into the classroom is provided. (CW)

The advantages of the use of videodiscs in elementary school science are stressed. A basic videodisc system is described. Questions to ask before investing in a videodisc system are suggested. Teaching techniques using the videodisc are discussed. (CW)

Presented are two lessons which illustrate acceleration for elementary school students. A poster for use in these activities is provided. Teaching methods used in these lessons are discussed. Student questions concerning automobile racing are presented with answers. (CW)

Data from the High School and Beyond study were used to investigate the comprehensiveness of programs in mathematics, science, and foreign language in large and small high schools. Large schools offered more comprehensive programs than did smaller schools, but there was substantial variation in comprehensiveness at any school size. (SLD)

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)

Described is a software package, "Trapeze," within which a routine called LinDis can be used. Discussed are teaching methods, the linear discriminant model and equations, the LinDis worksheet, and an example. The set up for this routine is included. (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)

Presents a picture of the curriculum at the Pullenvale Field Study Centre. The curriculum is based on a drama theme called "The Settlers," and relates to Year Five Social Studies. Describes the curriculum in its current form and its development. Also considers the cyclic process, involving planning, action, observation, and reflection.…
