Archimedes' principle-internet accessible remote experiment

Abstract

The development of new information technologies 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).
