This paper proposes a different experimental setup compared with the traditional ones, in order to determine the acceleration of gravity, which is carried out by using a fluid at a constant rotation. A computerized rotational system--by using a data acquisition system with specific software, a power amplifier and a rotary motion sensor--is…

The feasibility of using current software, such as PC-Duo, PCAnywhere or LabVIEW, in training students in instrumental analysis from a remote location is investigated. Findings show that creation of online features is crucial to the use and learning by students and the development of a suitable Web site, which provides an easy-to-use interface to…

Provides ideas for using the same port connection of personal computers to interface with laboratory instruments. Contains specific instructions on how to build transducers. Includes plans and diagrams for thermistors and light meters as well as computer programs for displaying instrument readings on monitors. (TW)

Presented are five ideas for A-level biology experiments using a laboratory computer interface. Topics investigated include photosynthesis, yeast growth, animal movements, pulse rates, and oxygen consumption and production by organisms. Includes instructions specific to the BBC computer system. (CW)

Discussed are various ways that microcomputers can be interfaced to laboratory equipment to control laboratory applications. A general overview is given including advantages and disadvantages of different interfaces. Different software tools currently available are examined. (CW)

Describes a chemistry lab experiment in which a microcomputer is used to graph data. In the experiment a catalyst is used to decompose a commercial bleach. The computer's game port is used with a potentiometer to plot the volume of oxygen gas produced versus elapsed time. Courseware information is included. (TW)

Described is a means of logging data from remote sensors in data files and then transferring the data to a spreadsheet for processing. The presentation of the data in tabular or graphical form is discussed. An example using temperature data from a model house is provided. (Author/CW)
