Experimental analysis of physical magnitudes through films and its application in the classroom

In this paper we show how our Secondary and High School students have been able to research phenomena or physical situation of their real lives closer to their interests in the last 10 years. The procedure is to make digital video recordings and then applying a computer program (Avimèca), which monitors the scene frame by frame and attaching numerical values to each selected point in order to analyze some physical magnitudes. Contrary to what may seem, the procedure is simple and relatively inexpensive elements are used. In any case, to make it easier for other teachers, a program guide is added which is free-access. In addition, the way in which we implemented this classroom activity is detailed, listing the difficulties encountered and the corresponding proposed solutions.
