Describes a laboratory designed to give students practical experiences with experimental phenomena discussed in lectures, focusing on laboratory organization and typical experiment. In addition to a list of experiments, three exercises are discussed: fluorescence/laser, ferromagnetic domains, and thermal population (which uses PET computer…

Traces the development of college physics laboratories. Discusses the motivating forces that produced these laboratories, sources of experiments and the first and most influential laboratory manual prepared by E. C. Pickering for use at the Massachusetts Institute of Technology. (JN)

Discusses how TOPS devices can be improved. New chemistry-physics devices are offered in hopes of encouraging teachers to invent other small devices for projection on a TOPS projector-adaptor. (HM)

Presents a simple, economical model of circulatory behavior that illustrates the effect of changes in cardiac output, peripheral resistance and compliance on arterial blood pressure. (CS)

Discusses some problem areas as they presently exist in many secondary school laboratories in Australia, and presents some views on how safety in science should be presented to the Australian students. (Author/HM)

Instructions for making a simple respirometer, to measure rates of oxygen consumption of organisms, are presented. The instrument incorporates most of the basic elements of commercial respirometers but can be made inexpensively by high school students. Operating instructions and applications are given. (Author/SA)

Introduces chemistry laboratories in which students have the opportunity to conduct laboratory projects in multiple sessions that promote planning, thinking, technical performance, and responsibility. Defines the process of experimentation and its applications to science laboratories and describes successful project applications. (YDS)

Examines the psychology of learning and its application to work in the laboratory. States that the working memory capacity of students is limited; therefore the amount of information they can process needs to be controlled and "recipe following" in the laboratory is perfectly reasonable. (RT)

Science educators are often among the first to use emerging technologies in the classroom and laboratory. For the technologically savvy science teacher, the handheld computer is a terrific tool. A handheld computer is a portable electronic device that helps organize (via calendars, contact lists, to-do lists) and integrate electronic data…

The purpose of this study was to survey the quantity and quality of laboratory work conducted by Grade 11 and 12 biology students in British Columbia High Schools, to analyze student performance on laboratory based questions on Provincial examinations, and to examine the curriculum for recommended laboratory work. Examination and curriculum data…

A MANUAL WAS PRODUCED CONTAINING LABORATORY PROCEDURES FOR A ONE-SEMESTER COURSE IN ELEMENTARY QUANTITATIVE CHEMISTRY ON A COLLEGE FRESHMAN LEVEL. MATERIALS AND TOPICS WERE EXAMINED AND CHOSEN AS TO DESIRABILITY, PRACTICALITY, AND EDUCATIONAL VALUE. OPTIONAL EXPERIMENTS WERE ALSO INCLUDED. THE LABORATORY PROCEDURES WERE TESTED ON SOPHOMORES AND ON…

Discussion of the botany lessons used at two schools points out the need for fifth and sixth grade students to be taught the principles of plant life through observations made at an experimental garden plot at the school. (ND)

This manometer is a modification of a design reported previously. It contains simplifications in the design of the manometer itself and in the associated electrical circuit. The apparatus is useful in the study of gas-phase reaction kinetics. (BB)

The goal of many colleges is to make the organic chemistry laboratory completely flameless by using electric heating equipment. Benefits of eliminating the Bunsen burner, electrical heating equipment and accessories, hazards remaining in flameless laboratories, and design standards related to laboratory liability are the major topic areas…

Presents specific techniques for lectures and demonstrations in acoustics for deaf students. (SK)
