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.…

This document provides abstracts of 116 laboratory experiments/demonstrations currently being utilized in all areas of engineering education at 52 universities across the United States. (SL)

Presented is a short discussion of factors causing color changes in animals. Also described is an activity which may be used to demonstrate the response of amphibian skin to a melanophore stimulating hormone in high school or college biology classes. (PEB)

Presents descriptions of three experimental procedures for physics classes: forced oscillations, measuring the refractive index of perspex, and measuring the critical potentials of helium. (SA)

Basic knowledge about Skylab experiments is presented in this book for the purpose of informing high school teachers about scientific research performed in orbit and enabling the teachers to broaden their scope of material selection. The seventh volume deals with the ability of the Skylab crew to live and work effectively in space. The content is…

Reported is a method of producing artificial lightning in an ordinary clear lightbulb. The appearance of sparks produced is that of a miniature stroke of forked lightning seen in natural thunderstorms. The sparks also show the intricate branching patterns often seen in natural lightning. (JT)

Since the major causes of accidents are carelessness and a negative or apathetic attitude towards safety, this guide was developed to facilitate safe, stimulating science laboratory activities by providing both general and specific safety information presented in 12 sections. Subject areas considered in these sections include: 1)…

This paper describes the construction and use of a simple salinometer. The salinometer is composed, mainly, of a milliammeter and a battery and uses the measurement of current flow to determine the salinity of water. A complete list of materials is given, as are details of construction and operation of the equipment. The use of the salinometer in…

The importance of introducing various projects or activities as a motivation towards inquiry-based learning, also satisfies the need for first year chemistry students to transfer scientific theory into practice. This approach, combined with the traditionally written laboratory methods, develops creative skills, and the spirit of exploration…

Recommendations are made for handling and growth of Beneckea natriegens, a rapidly growing, nonpathogenic marine bacterium which can be used with advantage to replace Escherichia coli in many undergraduate microbiology experiments. Examples of experiments and the potential value of this organism as a subject for student research projects are…

An enzyme exercise to address the problem of students inability to visualize chemical reaction at the molecular level is described. This exercise is designed as a dry lab exercise but can be modified into a classroom activity then can be augmented by a wet lab procedure, thereby providing students with a practical exposure to enzyme function.

This booklet of experiments was compiled from various teachers' guides in response to the many requests from students for help in preparing smoking demonstrations and exhibits. The booklet is divided into three sections. Part 1 illustrates a number of experiments, most of which require some laboratory equipment. Part 2 includes a number of…

Describes urinalysis techniques for dry weight measurement, examination of urinary calculi (stones), and determination of the presence of blood and blood pigments. Also presented are directions for preparing required reagents. (WB)

An exciting laboratory environment is activated by the preparation and novel use of magnetic materials to decontaminate water through adsorption and magnetic removal of metals and organics. This uncomplicated technique is also adaptable to the possible application of adsorbents to numerous other environmental substances.

This document presents a series of physics experiments which allow students to determine the value of unknown electrical capacitors. The exercises include both parallel and series connected capacitors. (SL)
