The article describes a school activity in which two different explanations of why airplanes fly are compared and discussed. […]
Anno XXXIX - n.2 - aprile/giugno 2006 La proposta di riforma Boselli e l’insegnamento della fisica
A law involving science curricula, proposed about one century ago, is analysed and its modern and still valid interpretation of science teaching and of the relationship between school education and the productive world is highlighted. […]
Anno XXXIX - n.3 - luglio/settembre 2006 Indagine su competenze in ambito scientifico in uscita dalla scuola media
We tested the achievement in physics and mathematics for boys and girls leaving the lower secondary school (“scuola media”, now “scuola secondaria di primo grado”) aged 14. The test consisted of 12 multiple choice questions and 4 simple problems. It was given to 1089 students, […]
Anno XXXIX - n.3 - luglio/settembre 2006 La fisica del buco
The true and genuine holes, in physics as well, go rather unnoticed owing to their absence of matter except when their presence entails functional problems. In the following, starting from simple problems and looking at the hole rather than at its surroundings, […]
Anno XXXIX - n.3 - luglio/settembre 2006 La formazione di gocce nei liquidi in caduta libera
The narrowing of a falling stream of liquid is a well-known demonstration of the equation of continuity. We consider the behavior at the bottom of the stream where the stream swells and forms droplets. Drop formation is illustrated by detailed photos of experiments. […]
Anno XXXIX - n.3 - luglio/settembre 2006 Per laboratorio il cielo: la III legge di Keplero
The Physics Department of the University of Milano organizes science activities for young students every year, among which astronomical observation sessions. In one experience, 16 to 19 year olds apply Kepler’s 3rd Law to the satellites of Jupiter. We describe the structure of this activity, […]
Anno XXXIX - n.3 - luglio/settembre 2006 Effetto Seebeck
This paper reports a teaching approach to the Seebeck effect, with attention to the historical, theoretical and experimental aspects. […]
Anno XXXIX - n.1 - gennaio/marzo 2006 L’opera scientifica di Ettore Majorana: cenni
This article celebrates the 100th anniversary of the birth of the Italian theoretical physicist Ettore Majorana, probably the brightest Italian theoretician of the XX century. We outline the significance of some of his publications and we recall his life through letters, […]
Anno XXXIX - n.1 - gennaio/marzo 2006 Low Cost – High Tech: esperimenti con moderni dispositivi di uso comune
This article describes a project for a new approach in physics teaching. The use of technological tools, well known to the audience, is the key starting point. Easy to assemble, hands-on experiments allow to reach a new insight on physical processes. […]
