Archimedes' Principle - Internet Accessible Remote Experiment

摘要

The development of new information technologies enables remote experimentation which is a commonly used method in university education at present time. To disseminate this method for secondary and primary school science education we choose one of the fundamental laws of physics used most in real life applications a€“ The Archimedes?′ principle. The contribution describes the procedure of developing of the remote experiment The Archimedes?′ principle using Internet School Experimental System (ISES) for hands on experiment and Easy Remote ISES software for transformation of this experiment to remote one, applied for the first time. The experiment consists of the mobile platform with the controlled and measured displacement, on which are placed three vessels with liquids. The bodies are suspended from the ISES dynamometers, measuring the resulting suspension force when they are dipped into liquid. The simultaneous measurement of the suspension force enables either 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).
