In most physics courses using multimedia, real experiments are represented as digital video demonstrations. These time-based media have the disadvantage that students are often in the state of passive learners. Also, traditional multimedia learning environments only allow for the selection of different digitized media, but the learning process is…

A common undergraduate chemical engineering experiment has been modified for on-line operation over the Internet. By adopting rapidly changing Internet and object component technologies, we developed a novel approach combining the Internet and regular laboratory equipment. The client-server applications use a Visual Basic and Labtech programming…

The main objective of this class experiment is to measure the activity of two metabolic enzymes in crude extract from bird pectoral muscle and to relate the differences to their mode of locomotion and ecology. The laboratory is adapted to stimulate the interest of wildlife management students to biochemistry. The enzymatic activities of cytochrome…

In this article we describe two simple experiments using an ion accelerator as an aid to the teaching of electromagnetism to high-school students. This is part of a programme developed by a Brazilian State funding agency (FAPERJ) which aims to help scientifically minded students take their first steps in research.

You can't see, smell or taste air - but here's an easy method for experimenting with it. (Editor)

Reports a qualitative experiment on the contraction of gases which has dramatic appeal to arouse student curiosity. (SL)

Points out the benefits of "sciencing"--helping children learn the methodology and processes of scientific investigation through the use of play experimentation. (SKC)

This book represents a "cookbook" for teachers of physics, a book of recipes for the preparation of demonstration experiments to illustrate the principles that make the subject of physics so fascinating. Illustrations and explanations of each demonstration are done in an easy-to-understand format. Each can be adapted to be used as a demonstration…

A History-of-Physics laboratory in which students can reproduce historically significant physics experiments is described. The methods and materials used in the experiments are essentially those used originally. The objective is to provide students with an opportunity to repeat the experiments and to appreciate the significance of each in its own…

The use of a logarithmic amplifier preceding an oscilloscope's vertical amplifier is described for physics teachers who want to demonstrate the exponential decay nature of some phenomena. (Author/SA)

Intended for the elementary teacher who lacks science teaching experience, this article presents tips for finding background information and for stocking a portable "science lab" with everyday materials. It also outlines 10 easy experiments. (SJL)

An activity is described that is designed to give students a chance to learn about speed by calculating their own running or walking speed and the speed of cars. (MP)

Describes an approach to incorporating cooperative learning into the anatomy laboratory without diminishing the quality of instruction of the subject matter. Discusses the background, organization of groups and group tasks, evaluation of the approach, and potential disadvantages of cooperative learning. Contains 11 references. (JRH)

Examines the relative effectiveness of the traditional lab method and the microcomputer-based laboratory (MBL) for improving student understanding. Examines three areas of achievement: graphing interpretation skills, and interpreting motion graphs and understanding of motion. Results indicate that MBL laboratories are more effective than…
