A method has been developed to measure the swing period of a simple pendulum automatically. The pendulum position is converted into a signal frequency by employing a simple electronic circuit that detects the intensity of infrared light reflected by the pendulum. The signal produced by the electronic circuit is sent to the microphone port and…

We present a simple computer-based laboratory experiment for evaluating absolute zero in degrees Celsius, which can be performed in college and undergraduate physical sciences laboratory courses. With a computer, absolute zero apparatus can help demonstrators or students to observe the relationship between temperature and pressure and use…

Introduces three physics experiments for high school and college classes. Topics include measuring the ratio of heat capacities using a microcomputer and a glass syringe, producing large electric sparks using a variation of a Leyden bucket, and observing transmission line behavior using television signals. Includes descriptions of materials and…

Introduces three different techniques to facilitate the measurement of speed and the associated kinematics and dynamics using a computer. Discusses sensing techniques using optical or ultrasonic sensors, interfacing with a computer, software routines for the interfaces, and other applications. Provides circuit diagrams, pictures, and a program to…

Briefly describes hardware and software requirements for a computer based learning system. The methods used in various systems are reviewed briefly. (TS)

Describes a course entitled Computer Applications in Science," offered by the Physics Department at Queen Mary College, London. Lists topics included in the lectures and topics handled by means of computer projects assigned to students. (Author/TS)

Identifies problems students have learning physics and explains how microcomputer-based laboratory (MBL) tools can help the learner. Describes the possibilities for instruction with MBL instruments and stresses the pedagogical advantages it has in the sciences. (ML)

Identifies specific science skill activities and discusses how they can be enhanced using the microcomputer in a laboratory setting. Highlights the benefits, advantages, and applications of microcomputers in physics laboratories. (ML)
