Anno XLIX - n.3 - luglio/settembre 2016 “Vedere” il calore
The availability of low-cost thermal imaging cameras connected to smartphones opens up interesting opportunities in schools. It is now easy to take infrared images and explore phenomena where heating is involved; it is now possible to “see” heat. This article describes some activities carried out in the classroom with a “smart” […]
Anno XXXIII - n.3 - luglio/settembre 2000 Vedi alla voce quanto
A hundred years ago Max Planck introduced the quantum of action concept; the anniversary is celebrated in many ways all over the world. In the present paper we want to stress that the Planck constant h ‘initially introduced to account for some facts in a field of research which seemed a marginal one’ […]
Anno XXXV - n.2 - aprile/giugno 2002 Velocità del suono in aria
The article describes an easily performable and understandable measurement of the velocity of sound in the air. […]
Anno XXV - n.3 - luglio/settembre 1992 Venti anni di effetto fotoelettrico (1887-1905)
After a concise description of the experimental aspects of the photoelectric effect, this article gives an account of me history of its discovery and of the research that followed, and discusses its contribution to the radical changes in the conceptual framework of physics from the last decade of the past century to Einstein’s work of 1905. […]
Anno XXXV - n.1 - gennaio/marzo 2002 Verifica della legge di Ampère con materiale “povero”
I propose an articulated and complete experimental exploration of Ampère’s law which can be performed with ordinary lab instrumentation. […]
Anno XXVI - n.4 - ottobre/dicembre 1993 Verifica di un modello della fotoconduzione nei semiconduttori, basato sull’analisi della risposta alla luce, in regime statico e dinamico, di una fotoresistenza al CdS
Photoconductive CdS cells are cheap solid state devices, suitable for a first understanding of the optical properties of semiconductors. This work presents two experiments, concerned with static and dynamic behaviours of a CdS cell, which allows us to verify simplified model explaining semiconductors’ […]
Anno XLIV - n.2 - aprile/giugno 2011 Video ad uso degli studenti di fisica
Communication technologies allow teachers to keep in touch with their pupils in case of absence and after school hours. […]
Anno XXXII - n.2 - aprile/giugno 1999 Visita all’osservatorio astronomico
Visiting the astronomical observatory is the occasion of a cultural growth. This visit, to be effective and incisive, must be prepared, before and during the course of it, by dealing with some basic contents. These should be selected according to a triple reference: the pupils’ […]
