Description of the Experience
I could not understand why at impurities the increase in temperature decreases conductance. I asked the teacher who told me that the electrical conductivity of metals is due to the degree of freedom of movement of electrons in the crystal lattice them. In the nodes of the crystal lattice metal ions are located, which oscillate continuously around which electrons move. By increasing the temperature the oscillation of the ions increases, and the presence of defects and impurities alter the structure of the lattice, and thus hampering the directional movement of the electrons, which reduces the electrical conductivity.


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.
