Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In…

Mass spectrometry is one of the few instrumental analysis techniques that can be relatively well-understood with physics/chemistry knowledge typical of an advanced high school or a beginning undergraduate student. This positions mass spectrometry well to be used as a bridge between abstract concepts typically set as learning goals in courses at…

Measuring voltage-current and voltage-power curves of a photovoltaic module is a nice experiment for high school and undergraduate students. In labs where real sunlight is not available this experiment requires a solar simulator. A prototype of a simulator using LED lamps has been manufactured and tested, and a comparison with classical halogen…

iSchlenk, a portable instructional cart with equipment for hands-on student experience in safe handling of air-sensitive, moisture-sensitive, toxic, pyrophoric, and/or radioactive chemical materials, is described. The cart, for use by =4 students, has compressed air and vacuum from a diaphragm vacuum pump supplied to 4 three-port Schlenk lines…

Physics teachers use experimental devices to show students how scientific concepts, principles, and laws are applied to understand the real world. This paper studies question generation of secondary and under-graduate university students when they are confronted with experimental devices in different but usual teaching situations: reading about…

Recently there have been newly launched ocean color satellites which target the coastlines at unprecedented scales. Science education curricula can benefit from the provision of small low-cost spectroradiometers and curriculum supplemental materials that can be incorporated in a "hands on" teaching approach to explain and demonstrate remote…

Discusses the advantages of using automated analytical procedures in providing rapid, inexpensive alternatives to traditional methods and in teaching skills used in many professions and industry. (CP)

Describes an apparatus designed for demonstrating electron and ion-optical principles. The apparatus consists of (1) a high-vacuum system and (2) electron-optical components. The teaching techniques used and the experiments conducted are reported. The apparatus won second prize in Demonstration Lecture Apparatus in the A.A.P.T. Apparatus…

This document describes the theory and mode of operation to be used with a cathode ray oscilloscope. Safety percautions to be taken, methods of calibration, and uses of the equipment in school operation are given. A brief "trouble-shooting" section and a bibliography of other reference is included.
