Una esperienza didattica con risultato incoraggiante

The high school introductory physics course is a particularly delicate moment. One must avoid giving the pupils the impression that physics is mainly related to text-book and school lab and not to real everyday life. This paper describes an experience in which the students were enabled to take a correct attitude towards physics from the start, while learning about heat, thermal conductivity and conductors, insulators, sources of heat and heating power. In textbooks, these concepts are usually covered in a few pages. This experience was developed over three months, but the results seem to be rather encouraging.
