“…The theory of relativity is currently part of the high school curricula in many countries [1][2][3][4][5][6][7][8][9][10][11][12][13]. Students are well aware that the Einstein's theory is based on the principle of relativity and on the fact that the speed of light in vacuum has the same value in all inertial frames of reference [14].…”

The special theory of relativity is currently included in the curricula of high school in many countries. For this reason, we often organize in-depth lessons on this topic and, in this paper, we summarize a lecture that we have given in some extra activities addressed to last year high school students stimulating pupils "to play" with Lorentz transformations. We found a simple relation that allows us to deduce the rest length of a relativistic train without knowing the relative velocity and without using the lorentz factor and spacetime distortions.

The so called modern physics is at present included in the curricula of high school. Therefore, we often organize in-depth lessons on quantum mechanics and on the special theory of relativity (SR). In the following sections, we want to show a lesson given by the first author of this paper. He proposes to students a proportion to deduce relativistic time dilation and length contraction without knowing the Lorentz transformations.

In recent years, the special theory of relativity (SR) has been included in high school curricula in almost all countries. In addition to the classic demonstrations of the relativity of time and lengths, another interesting relativistic phenomenon that is shown, is the transverse Doppler effect. Obviously it is not possible to rigorously prove, at the high school level, the final relation but, from it, we have analyzed some physical consequences using trigonometry. In this paper, which has a didactic aim, we summarize one of our lessons held during some of the in-depth lectures on relativity that we often organize for high school students in our area.
