Anno XLVI - n.4 - ottobre/dicembre 2013 Articolo Città della Scienza – appendice
A short story of the first Science Centre in Italy and its historical collections that were destroyed by fire and a description of the strategies used to stimulate school students’ or visitors’ interest in ancient scientific instruments, which are very different from modern ones. […]
Anno XXVI - n.4 - ottobre/dicembre 1993 Assorbimento di calore e aumento di temperatura sono sempre sinonimi?
There are many misconceptions about physics which cause learning problems. In this article – the first of a series devoted to dismantle these misconceptions – we’ll try to show how heat absorption and temperature rise are not always the same thing. […]
Anno XXXI - n.2 - aprile/giugno 1998 Attività didattiche nel laboratorio multimediale in linea. Integrazioni disciplinari, apprendimento e insegnamento collaborativi: l’esperienza dell’IPIA Medi di Palermo
A project aimed at decreasing the number of students who quit before ending the first school year is described in detail The target students are low achieving pupils of a vocational school, the project involves not only physics but also mathematics, […]
Anno XXXI - n.4 - ottobre/dicembre 1998 Blu del cielo e realtà degli atomi
After having worked on the evolution of the theories regarding why the sky is blue, a series of experiments is presented in order to make the phenomenon of light scattering easily understandable to students and to provide a possible teaching sequence on the topic. […]
Anno XXXI - n.1 - gennaio/marzo 1998 Campi, energia e lavoro. Motivazioni di una proposta
We enphasize here the educational reasons lying behind a reversal of the traditional approach to the introduction of work, energy, potential, and fields at high school level. The details of this approach have been fully described elsewhere. […]
Anno XXVIII - n.1 - gennaio/marzo 1995 Capire la Time-Resolved Reflectivity: una tecnica di analisi basata sull’interferenza da lamina sottile
Thin film interference is the basis of Time-Resolved Reflectivity (TRR), a technique used in condensed matter physics to study phase transformations. Two series of simple experiments are proposed: one employing microwaves, and the other visible and infrared laser light. By the microwave experiments we show the role played by the thickness and the refraction index of the film. […]
Anno XXXI - n.3 - luglio/settembre 1998 Che cosa ci insegnano i fenomeni di luce ed ombra sulla luna
Already in ancient times the observation of lunar phases and eclipses allowed to speculate on the distances of sun and moon and to estimate the moon’s dimensions. The article, based on the writings of Aristarchus, shows how the phenom-enological observations can lead to a comprehensible general atronomical view of the Earth, […]
Anno XLVI - n.4 - ottobre/dicembre 2013 Città della Scienza: una storia dei nostri tempi
A short story of the first Science Centre in Italy and its historical collections that were destroyed by fire and a description of the strategies used to stimulate school students’ or visitors’ interest in ancient scientific instruments, which are very different from modern ones. […]
Anno XXXI - n.2 - aprile/giugno 1998 Come valorizzare un antico esperimento didattico con la tecnica MBL: la macchina di Atwood per condurre una ricerca sperimentale sul moto
Atwood’s machine is a device born in the XVIII century as an aid for teaching mechanics; a reduced and simplified version of such device still appears in physics textbooks, as an application of Newton’s second law. An Atwood’s machine interfaced to a PC by means of position and force sensors becomes a device for a detailed investigation on the motion of bodies subject to forces that change with position. […]
