Anno XXXII - n.1 - gennaio/marzo 1999 Membrane saponose e loro tensione superficiale
Soap bubbles and soap films are interesting and amusing. This article describes an experiment on soap films which can be used at secondary school level that involves forming a film with the shape of a deformed quadrilateral in an area bounded by two rigid straws and two pieces of thread of equal length attached to their ends (Fig. […]
Anno XXVII - n.1 - gennaio/marzo 1994 Misura della circonferenza terrestre col metodo di Eratostene.
This article describes an experiment done by first-year secondary school pupils, who measured me radius of the Earth with the method of Erathosthenes. For this purpose, cooperation was sought for and put into effect on long European distances, ranging from the island of Pantelleria in the Mediterranean to Goteborg in Sweden. […]
Anno XLVII - n.2 - aprile/giugno 2014 Misura della componente orizzontale del campo magnetico terrestre mediante una bilancia elettromagnetica costruita in casa
We report an experiment for measuring the horizontal component of the Earth’s magnetic field using easily available material, explaining how some conditions that optimize the results were obtained using a rectangular coil. […]
Anno XXXI - n.3 - luglio/settembre 1998 Misura della costante h/e (costante di Planck/carica elementare) mediante diodi L.E.D.
By means of some LEDs (Light Emitting Diodes) used as quasi-monochromatic light sources at different wavelengths and measuring their forward voltage at a fixed value of the current one can obtain the ratio of Planck’s constant to elementary charge with an estimated error of the order of 6%. […]
Anno XXVIII - n.3 - luglio/settembre 1995 Misura della lunghezza d’onda della luce con un disco microsolco
This article describes how it is possible to measure the light wavelength using a phonograph microgroove disc. […]
Anno XLVII - n.3 - luglio/settembre 2014 Misura della velocità della luce con mezzi modici
A simple way of measuring the speed of light in an educational context using one or a couple of mirrors and some easily available common electronic equipment is described. […]
Anno XLVIII - n.3 - luglio/settembre 2015 Misurare pi-greco
This article describes an activity aimed at measuring the value of pi. Five methods, were used, all of them easy to perform. All results agree with the known value within 1%. The activity is suitable to introduce the concept of measurement uncertainty at the beginning of Physics Classes. […]
Anno XLVI - n.2 - aprile/giugno 2013 Misure elettriche svolte in Australia tramite un PC in provincia di Milano
By connecting to an Australian university lab ( http://netlab.unisa.edu.au) two Italian last-year highschool classes work with electric circuits in real time and in remote. The description of one of the activities shows the diverse interesting learning advantages offered by this kind of far away real time experimenting […]
Anno XLVII - n.1 - gennaio/marzo 2014 Modelli per l’agitazione termica
Models that can help to understand the mechanisms of some phenomena that occur in liquids, such as evaporation and distillation, and some aspects of the kinetic theory of gases are described […]
Anno XLVIII - n.4 - ottobre/dicembre 2015 Molle ferme e molle in vibrazione: qualche sperimentazione su elasticità e risonanza
This article reports about some experiments on the physics of resonance and elasticity. Employing a simple setup it is possible to identify the longitudinal eigenmodes of a stretched massive spring and to study their behaviour under the conditions of forced and damped motion. […]
