Conducting experiments in physics using modern measuring techniques, and particularly those
utilizing computers, is often much more attractive to students than conducting experiments
conventionally. However, the cost of professional kits in the Czech Republic is still very expensive
for many schools. The basic equipment for one student workplace in the case of professional kits
such as Vernier, Pasco or Coach costs around 800 euros. In this paper some physics experiments in
which a computer, or a tablet with Microsoft Windows, is used as the measuring device, along with
available physical devices such as a laser pointer, a solar cell or an electret microphone, are
presented as suitable and alternative ways to carry out lab work. We show that it is possible to
perform very simple school experiments (both as a central demonstration and as individual
experimentation), in which high accuracy and clear final conclusions can be achieved at a very low
cost. Further information is publis…
