Fourier transform nuclear magnetic resonance (NMR) is a new spectroscopic technique that is often omitted from undergraduate curricula because of lack of instructional materials. Therefore, information is provided to introduce students to the technique of data collection and transformation into the frequency domain. (JN)

Discusses various software packages which help science and mathematics students make sense out of data (formulating hypotheses, interpreting graphs, analyzing possibilities, and collecting data with real-time graphing). Includes a list of commercially available programs for the areas, with program name, publisher, grade level(s), price, and…

Lists and describes representative software for Macintosh microcomputers. Included are Apple University Consortium software, word processing software, statistics packages, integrated packages, database management systems, and others. Source of software and costs (when available) are included. (JN)

Discusses various topics related to the interfacing of computers, focusing particularly on methods of data collection using instruments. Topics include serial digital connections (examining RS 232C and V.24, physical protocol, electrical protocol, and other areas) and parallel digital connections. (JN)

Graphs and charts are discussed in terms of levels of applications and skills necessary for effective use. Five activities, most appropriate for upper-elementary or junior high students, are suggested. (MK)

Discusses the use of an external analog-digital converter to use a computer as a storage oscilloscope. Provides program listings for use as a unipolar or bipolar voltmeter and storage oscilloscope. Schematics and component list are included. (JM)

Teaching mathematics as one would teach a science course (that is, as a field of intellectual inquiry) is advocated. Four illustrative activities, most appropriate for grades 5-8, are suggested. (MK)

Explains the typical design, operation, and calibration of a traditional psychrometer. Presents the method utilized for this class project with design considerations, calibration techniques, remote data sensing schematic, and specifics of the implementation process. (JJK)

Describes the electrical and material characteristics of a wide variety of sensors and switches, as well as methods for connecting them to computers that are equipped with a joystick interface. Includes a BASIC computer program that facilitates automation of science experiments and storage of data gathered with simple transducers and sensors.…

Uses a printed sheet of paper to represent a plant population in a given area. Quadrat sampling is simulated by dropping a square coverslip on the sheet and recording the symbols under the coverslip. Line-transect method is simulated by having a student randomly adjust the sheet under a string. (GS)

Reviews background of atomic absorption spectrometry techniques. Discusses problems encountered and precautions to be taken in determining trace elements in the parts-per-billion concentration range and below. Concentrates on determining chromium in biological samples by graphite furnace atomic absorption. Considers other elements, matrices, and…

Reviews three functions performed by modern computing integrators: (1) data acquisition; (2) data processing; and (3) communication. Also shows with examples how new electronic components enhance the functions of this popular analytical instrument in those areas. (JN)

Suggested activities for data collection and manipulation in the middle/junior high school are provided. The activities also help students to learn other process skills such as constructing graphs, describing relationships between variables, and analyzing their investigations. (JN)

Developed is a classroom activity that illustrates the scientific method. The importance of observation, interpretation, and prediction is discussed. The activity uses pictures of the surface of Mars. (KR)
