  This contribution shows that the main topics of Relativity can be discussed
at an elementary level and in a considerable extent - including the formal
results of "Time Dilation" and "Lorentz Contraction" - by a minor modification
of the usual mathematical formalism employed to describe uniform and
accelerated motion. The proposed strategy begins with a "free-fall" experiment,
followed by a discussion of the results in order to include deviations of the
experimental data with respect to the conventional kinematics model.
