This section of the journal includes several short notes on science activities and materials for secondary schools. Activities and materials are included that relate to biology, microbiology, microcomputers, chemistry, and physics. (RH)

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.…

This note describes an inexpensive means for making high resolution analog voltage measurements using the parallel printer port of a standard IBM PC or compatible. (PR)

This curriculum guide presents 100 lessons for an advanced placement course on programming in Pascal. Some of the topics covered include arrays, sorting, strings, sets, records, computers in society, files, stacks, queues, linked lists, binary trees, searching, hashing, and chaining. Performance objectives, vocabulary, motivation, aim,…

The use of computers in classrooms to support and extend instruction is a topic which is being discussed in major educational forums across the United States. Until a few years ago, computer use in schools was the exclusive domain of the mathematics department. Other content areas have now found ways to use computers to enhance their instruction.…

Describes the state-of-the-art in computer interfacing in the biology laboratory. Discusses hardware and software. Enumerates the educational benefits from instrumentation such as cost effectiveness and increased student opportunity and motivation. Includes 14 references. (CW)

Described is how spreadsheet and problem solver microcomputer programs may assist students in performing mathematical calculations. Discussed is the application of the equation solver "MathCAD" to various areas in the undergraduate curriculum. (KR)

Describes the methods and materials used to obtain satellite pictures from weather satellites. Discusses possible physics lessons which can be done using this equipment including orbital mechanics, and how the satellite works. (CW)

Technology can support hands-on science as elementary students use computers to formulate field guides to nature surrounding their school. Students examine other field guides; open databases for recording information; collect, draw, and identify plants, insects, and animals; enter data into the database; then generate a computerized field guide.…

Described is the use of the microcomputer and interfacing equipment to obtain weather data from meteorological satellites. Equipment necessary for this type of remote sensing, including constructing and/or obtaining the necessary hardware and software is discussed. Ideas for the integration of this material into the curriculum are presented. (CW)

Described is an activity in which a computer is used to acquire temperature and humidity data useful in investigating transpiration in plants. Materials and procedures are discussed and examples of results are presented. Factors which influence the rate of transpiration are discussed. (CW)

Described is a simple electronic interface that can receive signals from up to four analog sensors and four event detectors and save the data on disk. Schematic diagrams, construction details, sample temperature plot and weather station logging programs, and a parts list are included. (KR)

Presents a technique that allows high school biology students to view materials not normally seen in the laboratory environment using a computer and videodisk technology. (MDH)

Presented are four activities which are designed to familiarize children with the multiple uses of computers and help them learn about heat and temperature using temperature probes. Included are the tempering effect of water, heat capacity, caloric content of foods, and weather. Hardware and software are discussed. (CW)
