Abstract
The problem of impedance matching is not usually treated in Italian High School, though it is a central topic in every waves propagation phenomenon. Strictly related to the efficiency in energy transmission, a good impedance matching plays a key role in avoiding signal losses caused by undue reflections at the boundary between two different media. Impedance matching applies when dealing, as an example, with human physiology, medical diagnostic, musical instruments assembling, electronic transmission lines, seismic damage risk evaluation, etc. The PLS (Piano Lauree Scientifiche) UNIMI Team proposes to High School students and teachers, a laboratory discovery path that explores the consequences of impedance matching or not matching in everyday life. Being targeted to High School students, the discussion is not meant to be exhaustive. Instead the aim is that students will both learn how to recognize, in different physical phenomena, a common characteristic wave property, and develop citizenship awareness in situations like, as an example, the occurrence of a medical examination or the occurrence of risky natural events.
