  In the last years it is becoming more and more evident the importance in
providing to the students, and people in general, a more realistic view on the
scientific research world. In this framework many initiatives are beeing
carried out to put students closer to scientists. The Astrophysics Masterclass,
held in our Department, is an example of such activities, consisting in a
one-day outreach event during which high school students experience the
research methods in the astrophysics field. In this paper we describe this
activity, which allows the participants to work on real research data in a real
research center.
