Abstract:
In this now days, the interest for the study of Physics decreases considerable. This is why the teacher must find the adequate methods in each case, in a way in which the Physics does not appear like an abstract discipline, hard of understanding. In this purpose we achieved with the students a device from the recyclable materials with can be observed the fact that the air tends to oppose the movement of the objects and that the force of resistance depends on the form of the object. can allow the determination of the Form Factor in turbulence system and evidence the force of friction between the object and the air. Also, there can be established the speed of the air jet produced by a hair dryer or by any other system of the air blower type. This experiment has determined the development of practical and intelectual abilities of students, the development of creativity, skills of individual and group work. Also, the students understood how they can realise a scientific step, that for creation you need work and tenaciously consciousness because the effort, the information stocking and the experience are decisive. Thomas Alva Edison said that: ”the genius represents only 1% inspiration, 99% being perspiration”. Also, the students observed that learning Physics they make a contribution at the development of the society, at the increase of life quality. They learned to value work and the effort deposited by our precursors and by our contemporaryes. The active implication in the realising of the experiment and the interpretation of results determined them to learn Physics with pleasure and with interest!
