A tutorial, in which inertial and gravitational mass meanings were scanned according Newton and Mach, was made up in the summer school IDIFO3 (Udine, 2011, addressed to high-school skilled students). Quadrimomentum was defined through proper time and 4-displacement by analogy with classic momentum, relativistic kinetic energy was introduced passing for the Newtonian limit, mass was related to rest-energy. Ways of looking at mass as well as scientific meanings of mass emerged were analyzed. “Relativistic mass” was inquired separately. Data analysis enlightened pupils’ learning of mass-energy equivalence and allowed recognizing the physical representations of mass devised by Domenech et al.
