The Van de Graaff (VDG) generator is ubiquitous in the physics laboratory, but the high-voltage discharges that emanate from it can cause user discomfort or damage to nearby electronics during experimentation. In this work, an augmented reality (AR) tool is developed to help students conduct the experiment safely. More specifically, it allows them…

This newsletter is composed of brief notes in the various areas of science. Biology Notes include hazards of tasting Phenylthiocarbamide in laboratory experiments, the use of Albustic and Clinistix test papers for protein and glucose determinations, the measurement of the respiratory quotient, and the construction of a simple respirometer. Physics…

Describes the construction and application of a device small enough to be worn on a worker's clothing that can monitor exposure to mercury. (MLH)

Experimental data, Federal and State regulations, and user data are presented to assess the safety factors of low-power lasers. General safety precautions, basic laser theory, the place of the laser in the classroom, and some introductory exercises are also presented. (Author/TS)

Describes the experimental arrangement for x-ray analysis of samples which involves the following: the radioisotopic x-ray disk source; a student-built fluorescence chamber; the energy dispersive x-ray detector, linear amplifier and bias supply; and a multichannel pulse height analyzer. (GS)

Describes the construction and operational procedures of a simple setup which enables undergraduate students to conduct experiments on critical phenomena in gases. Indicates that the experimental features are proved comparable to those of the Reamer and Sage apparatus. (CC)

This Physics Laboratory Project Book, assembled through a survey of science instructors in vocational-technical schools in Connecticut, is an extension of the Chemistry-Materials Laboratory Project Book (see note) and is intended to meet a variety of needs. It can serve as an idea book, with the instructor taking from it as needed and adding or…

THIS IS THE THIRD IN A SERIES OF GENERAL BIBLIOGRAPHIES WHICH ARE BEING DEVELOPED TO DISSEMINATE INFORMATION CONCERNING DOCUMENTS ANALYZED AT THE ERIC INFORMATION ANALYSIS CENTER FOR SCIENCE EDUCATION. REPORTED ARE OVER 200 CITATIONS TO SELECTED DOCUMENTS RELATED TO EQUIPMENT AND MATERIALS FOR TEACHING AND LEARNING SCIENCE. THE DOCUMENTS INCLUDED…

This teacher's guide was developed for use in junior and senior high schools in Duval County, Jacksonville, Florida, for the purpose of identifying those secondary science laboratory experiences which are essential to the development of science content knowledge and competency in handling science laboratory equipment and consumables. The guide…
