Describes laboratory procedures, demonstrations, and classroom activities/materials, including chi-square tests on a microcomputer, an integrated biology game, microscope slides of leaf stomata, culturing soil nematodes, technique for watering locust egg-laying tubes, hazards of biological chemicals (such as benzene, benzidene, calchicine,…

Presents background information, laboratory procedures, classroom materials/activities, and chemistry experiments. Topics include sublimation, electronegativity, electrolysis, experimental aspects of strontianite, halide test, evaluation of present and future computer programs in chemistry, formula building, care of glass/saturated calomel…

The purpose of this study was to investigate the effects of scientific discussions based on student-constructed pre- and post-laboratory concept maps on students' attitudes toward chemistry laboratory in the university general chemistry. As part of instruction, during the first four laboratory sessions, students were taught how to construct and…

This high school chemistry resource is an on-screen chemistry lab. In the program, students can experiment with a huge range of chemicals, choosing the form, quantity and concentrations. Dangerous or difficult experiments can be investigated safely and easily. A vast range of equipment can be set up, and complex simulations can be put together and…

This document proposes that preservice teachers assess various learning philosophies to find methods that may be useful in teaching at the higher education level. In the first section of the paper ten broad principles of teaching are cited: developing and maintaining student interest; motivating learners; providing useful learning opportunities;…

This paper describes the Project for Integrating the University, the School, and Society (PIUES), developed as part of an effort to restructure the teaching of engineering at the Pontifical Catholic University in Rio de Janeiro, Brazil. New courses for high school teachers were developed that focused on the debates over basic concepts in…

In preparing this volume, every effort has been made to ensure accuracy, the most recent authorities have been consulted, and it is believed that a faithful view is presented of the various sciences embraced, as far as they are at present developed. It is the intention of the author to keep his book up to the times by constant revision, and to…

Discusses laboratory procedures, classroom materials, and demonstrations including: a model for metallic/ionic structures; Friedel-Crafts acylation reaction; aids to teaching crystal structure; a metal displacement project; silver recovery from fixer and silver residues; iodine sublimation; nature of acids; card models for teaching bonding; and…

Outlines methodology, demonstrations, and materials including: an inexpensive wave machine; speed of sound in carbon dioxide; diffraction grating method for measuring spectral line wavelength; linear electronic thermometer; analogy for bromine diffusion; direct reading refractice index meter; inexpensive integrated circuit spectrophotometer; and…

Outlines a variety of laboratory procedures, discussions, and demonstrations including polarizing power and chemical properties of copper and zinc, preparation of boron coordination complex, demonstration of amino-acid synthesis in the primordial environment, classification and reactions of carbohydrates, and four others.

Science activities with soap bubbles for primary school children are described in this article. Another activity involves children in determining the whereabouts of sugar as it dissolves in water. (SA)

Varying aspects of the study of psychology are discussed focusing on the shortcomings of the traditional definition of psychology as the study of behavior. Effects of cognitive, experimental, and applied psychology are examined, and a general concept of psychology as the study of the mind and mental processes is advanced. (BH)

Discusses the format of a semester course and provides details about grading, formative assessment, research papers, lecture activities, cooperative examinations, use of spreadsheets, and open-ended laboratory projects. Contains 15 references. (DDR)

Eight activities for use in the science classroom are presented. Included are insect collecting, laboratory procedures and safety, recycling, current events, variable manipulation, scientific method, electricity, and mechanics (Newton's Second Law of Motion). (KR)
