Archimedes' Principle - Internet Accessible Remote Experiment

Abstract

Abstract-The development of new informationtechnologies is enabling remote experimentation, a common practice in university education. This contribution describes the procedure of developing the remote experiment-the Archimedes´ Principle-using the Internet School Experimental System (ISES) for hands on experimentation and Easy Remote ISES software for transformation of this experiment to a remote one, applied for the first time. The experiment consists of the mobile platform with controlled and measured displacement, on which were placed three vessels with liquids. The bodies were suspended from the ISES dynamometers, measuring the resulting suspension force when they were dipped into liquid. The simultaneous measurement of the suspension force enabled recording of the weight, total force or buoyancy force alone. The experiment is available on http://remotelab9.truni.sk as a part of e-laboratory in Trnava, Slovakia (http://kf.truni.sk/remotelab).

Archimedes’ principle experimental apparatus for remote physics laboratory

“…The stepper motor is computerized and controlled to immerse the object into the liquid. Meanwhile, compared to research [7], the difference is in the type of sensor used and the data collection process. The Dual-Range Force Sensor from Vernier Technology was used in this study, and the event collected data by entering.…”

“…A similar apparatus was also developed by Ozvoldová et al [7], who developed an experimental apparatus based on Archimedes' principle for remote experiments. They reported that the object was hung on a dynamometer connected to a computer.…”

“…This software control allows full control of the data acquisition process to support remote experimentation. In research [7], software control was carried out in a container with liquid. Shocks may occur in the liquid, interfering in the data obtained.…”
