Description of the Experience
In physics we cannot know the exact measurement of a physical quantity, because of the imprecision of measuring instruments created by man.
I did not know this thing, as long as our professor of physics through an experience carried out in laboratory, showed it to me and my classmates. More specifically he showed how to know, or in some cases calculate the error of a measurement, in this case the side of a rectangle cardboard.
With this experience I managed to understand the topic and how it is possible to find the error a measurement that, as our professor told us “in most cases the error is caused by the uncertainty of the instrument used”.

Dissemination Seminar in Florence

31 October 2015 The seminar has been held in ITIS “A. Meucci” one of the schools involved within Goerudio project activities. Its main aim was to promote the results of the project toward a broad sample of stakeholders even overcrossing the number of people directly involved in the production of project outcomes. This purpose has been totally achieved especially thanks to the participation of students and teachers coming from different schools or from other classes instead of those ones directly involved within the project activities.
