Anno XXVII - n.2 - aprile/giugno 1994 Un esperimento sulla legge di Lenz. (Traduzione da The Physics Teacher, febbraio 1992, a cura di Giacomo Torzo)
The Lenz law is studied experimentally using a permanent magnet falling inside metal tube. A home made force sensor is used to measure the weight of the tube and steady magnet before the experiment, and then to weight the vertically suspended tube when the magnet is dropped. […]
Anno XLI - n.4 - ottobre/dicembre 2008 Un gioco di P. A. M. Dirac
An ingenious and amusing activity originally devised by Dirac illustrates a topological symmetry property of the three-dimensional rotation of solids. Some mathematical aspects of this property and its relevance to the quantum physics description of fermions are explained. […]
Anno XXIII - n.1 - gennaio/marzo 1990 Un’idea per un trasduttore di temperatura
This article shows how students can be taught the concept of using a transducer to measure the temperature with a very simple electronic circuit in which a NTC thermistor acts as sensor. Only a basic knowledge of the main properties of transistors and thermistors is required. […]
Anno XXVIII - n.3 - luglio/settembre 1995 Un’indagine sulle preconoscenze dei ragazzi in merito alla struttura della materia
This paper presents the results of an enquiry on the ideas about Structure of Matter initially held by secondary school students. […]
Anno XXXVIII - n.4 - ottobre/dicembre 2005 Un’intervista a Einstein
Two weeks before Einstein died he was visited by a historian of science. They sat in Einstein’s study and discussed some of his illustrious predecessors in the evolution of physics. […]
Anno XXVI - n.3 - luglio/settembre 1993 Un itinerario didattico introduttivo all’insegnamento dell’ottica
We present a recently developed project for teaching optics to 14-15 year old students. Pointing out some shortcomings of the traditional approaches, we take into account the students’ common sense “preconceptions” investigated in various inquiries. The teaching pattern we propose is rooted in everyday experience and the aim is to answer immediately questions such as: “how can we see what we see?”. […]
Anno XLII - n.1 - gennaio/marzo 2009 Un laboratorio all’aperto
The article suggests an easily reproducible statistical procedure for searching natural phenomena for regularities. […]
