Scientific experiments performed by students - a benefit for the educational process

摘要

This paper describes how an aerodynamic experiment is performed andreveals the fact that using a device made out of ordinary materials found in households,it is possible to determine: the speed of an air jet, the geometric dimensions of theobjects used or the form factor. One can also determine the displacement of an objecttowards the equilibrium position at different temperatures and locations on the globe. Itis pointed out that although we are not in the position to achieve all the practicalconditions for the experiment, we can extrapolate the theoretical results. It is alsoemphasised the fact that in carrying out a scientific experiment one should take intoaccount all the variables, not only the one which is analyzed. The experimental resultsare important, as well as the benefits acquired by an educational process based on amodern didactic approach oriented towards this subject of study.
