Περίληψη

The friction is a physical phenomenon, which impedes the movement of an object on the surface of another one. In the case of an object moves on a horizontal level, the friction depends on two factors: the weight of the moving object and the nature of the surfaces in contact. If a child understands that the movement of an object on a horizontal level depends on these two factors, then in fact he handles in a functional way the parameters that the friction is related to. In this study, is presented an effort of teaching interaction with pre-school children, having as an object toe understanding of the factors that the friction depends on when it is performed on an object that freely moves on a horizontal surface.
