The problem of the uncooperative experiment arises with the use of human subjects. Evidence shows that typical volunteer subjects have the following characteristics: better education, higher paying jobs, greater need for approval, lower authoritarianism, higher I.Q. score, and better adjustment to personal questions than nonvolunteers. Data also…

The purpose of this study is to determine categories of learning styles based on research on the chemical and physiological correlates of learning, as well as the development of simple measures that would allow an investigator to place a subject within one or more of these categories. The data from eight experiments with rats suggests that there…

Provided are 45 experiments in chemistry which have been used successfully by students in secondary school chemistry classrooms. Additional investigations directed at further inquiry on the part of the student are included. The experiments are directed at the development of science process skills and many of the concepts and generalizations which…

The twenty experiments in this text have been designed to give the scientific glassblowing technician the opportunity to use scientific glass apparatus in the study of physical science. Primary emphasis of these experiments is on the practical application of the physical science program as a working tool for the scientific glassblowing technician.…

An innovative and effective laboratory experiment of chemical reference literature is reported. The objectives of the experiment are to acquaint the first term student of college chemistry with the vast source of chemical literature that is available to him; to raise the general level of scientific literacy of these first term college students;…

The indroduction of on-line data collection and data processing techniques into an intermediate physics laboratory is described. Using a minimum configuration PDP-8L and a Digital Equipment AD01 analog to digital converter, an interface is developed with two existing experiments. These are a microwave apparatus used to simulate Bragg diffraction…

This physics laboratory manual is the result of curriculum development begun at Aviation High School (New York City) in 1967. It represents a semester of advanced laboratory work for those students who have completed the usual course in physics. The 91 laboratory experiments included in the manual have been developed and modified through use for…

Describes a kinetics experiment that utilizes timed reactions and colored endpoints and is suitable for large laboratory sections. (MLH)

Describes an engineering course that stresses various philosophies and methodologies of experimentation, along with the techniques of experimental synthesis. (MLH)

Describes an experiment that utilizes spectrophotometric equipment to analyze the kinetics of a homogeneous reaction in batch. (MLH)

Describes a set of experiments that uses a low-power gas laser to demonstrate difficult physical and mathematical concepts. (MLH)

This article describes how a gas chromatograph may be used to determine the amount of carbon dioxide in exhaled air. The experiment has been used as part of a demonstration exercise at a local science fair and proved of interest to all age groups. (Author/BB)

A simple experiment is described to measure the diffusion coefficient of a solute in a fluid. Laboratory-made floats are used to monitor the density changes associated with diffusion behavior. The experiment is ideally suited for undergraduate project work. (BB)

The use of the earthworm as a laboratory animal for studying the effect of starvation on nitrogen metabolism is discussed. Simple techniques and methods are presented allowing in vivo physiological responses to be compared with changes in the enzyme potential of gut tissue. (Author/MA)

Explains what superheated liquids are and how they are prepared. (BB)
