Using a computer and thermistor probes, students analyze graphs of temperature versus time. The experiment demonstrates phase changes in water, which can lead to a broader interpretation of matter, its properties, and the laws of thermodynamics. (Author/AIM)

Describes the use of magnetic field probes interfaced to a microcomputer in measuring the magnetic field in and around a solenoidal "Slinky" spring toy carrying a current of a few amps. (JRH)

Describes a teaching method using computer probeware to enhance students' laboratory experiences. Discusses the role of computer probeware in the science classroom, how probeware affects learning, and how it affects efficiency. (KHR)

Describes simple inexpensive modifications to existing equipment that facilitate the computerization of interference and diffraction experiments done in introductory laboratory courses. (JRH)

Describes a course for science education majors that explores the uses of computer-interfaced experiments in a variety of interesting activities. Several examples of biology experiments are given. (ZWH)

Describes the use of microcomputers in physics experiments to extend powers of observation, increase the accuracy of measurements taken, and obtain large amounts of high quality information, especially continuous and rapidly changing/moving data. Discusses software for interfacing a microcomputer with mechanics experiments. (JRH)

Contains an illustration and text to aid in describing the DynaPulse 200M Education Edition microcomputer-based laboratory (MBL), which combines interactive software with curriculum and medical instruction to teach students about the cardiovascular system. Review includes key features of the software, cost, and ease of use. (ZWH)

ExCELS is a program that supports teachers interested in the use of computer interfacing at the secondary school level. This paper describes an ExCEL-based course developed for science education majors, presents an overview of interface apparatus and how it is used in schools, and gives examples of experiments performed.

Describes an experiment to study the motion of a rocket-propelled vehicle over the entire duration of the engine burn using a video system with a frame-by-frame playback and a Sonic Ranger for ultrasonic position movements. Enables students to study the impulse-momentum principle and the effects of a time-varying force. (JRH)

Describes the National ADC0804, an inexpensive and readily available integrated ADC converter that can convert an analog voltage to an 8-bit signal. Includes schematic drawings. (DDR)

Presents a distillation experiment that uses temperature sensors connected to a computer in place of thermometers, and enables the whole class to view the data on a monitor and interpret and discuss the data in real time. (JRH)

Describes the use of a computer-linked camera to demonstrate Coulomb's law. Suggests a way of reducing the difficulties in presenting Coulomb's law by teaching the inverse square law of gravity and the inverse square law of electricity in the same unit. (AIM)

Describes a simple computer-interfaced experiment for recording the response of an RC network to direct current and square input signals. Undertakes a systematic qualitative and quantitative analysis for the high- and low-pass configurations. Suggests some examples of open-ended problems to develop a feel for circuit behavior. (AIM)
