Anno XLIV - n.4 - ottobre/dicembre 2011 Un semplice spettroscopio
Measuring light spectra with a simple homemade grating spectroscope. […]
Anno XXXI - n.3 - luglio/settembre 1998 Una bambola che cambia colore
A simple to make but not so simple to explain experiment on polarized light is described and explained. […]
Anno XLVI - n.2 - aprile/giugno 2013 Una caccia al tesoro scientifica: dove sta l’accelerometro in uno smartphone?
Current smartphones are equipped with many sensors and that offer a wide choice of applications like measuring accelerations, sounds, distances, angles, etc. Smartphones are becoming increasingly widespread among students who could use them as “personal instruments” for physics measurements. The article describes a kind of scientific treasure hunt: finding the location of the smartphone’s accelerometers by applying the laws of physics of uniform circular motion […]
Anno XXXI - n.3 - luglio/settembre 1998 Una geometria alternativa per la definizione operativa del vettore induzione magnetica B
The article describes some experiments, with a new geometrical approach, on the relationship between the magnetic force on a conductor, electric current and length. […]
Anno XXXII - n.1 - gennaio/marzo 1999 Una lampada al sodio di basso costo
Low pressure discharge lamps, filled with mercury or sodium, are commonly used for highways and tunnels illumination, especially against fog. A simple, low cost, monochromatic light source may be obtained by means a sodium lamp of this type. […]
Anno XXV - n.2 - aprile/giugno 1992 Una misura della densità dell’aria
We describe, in this paper, a measurement of the density of air, using the equation of state for gases and Archimede’s law. […]
Anno XXVIII - n.4 - ottobre/dicembre 1995 Una misurazione elettrolitica della carica dell’elettrone
A simple electrolytic experiment suited to students’ practical work allows to find an approximate value for the charge of the electron in a relatively short time and without having to make sensitive direct measurements of mass with 1 mg scales, not easily found in school labs. […]
Anno XXVII - n.2 - aprile/giugno 1994 Una verifica della legge della circuitazione di Ampère. (traduzione da Am. J. Phys., vol. 58, n. 6, giugno 1990, a cura di Giacomo Torzo)
Using a Hall probe and a coil fed by a constant current, the line integral Ampere’s law can be measured. A simple method to approximate the integral by a finite sum is reported. […]
Anno XXIX - n.2 - aprile/giugno 1996 Una versione moderna dell’esperimento di Fourier sulla conduzione termica entro un anello di metallo
This work deals with a famous historical experiment, i.e. the experiment that allowed Fourier to establish his theorem about the series expansion of a periodic function. In our experiment, that deals also with many aspects of the theory of heat, we warmed up an aluminium ring by means of a flame pointed towards a single point of the ring. […]
Anno XLIV - n.3 - luglio/settembre 2011 Usare lo schermo di un computer portatile per modellizzare campi di forze
A highschool-oriented experimental activity enhances the students understanding of the structures of fields surrounding planar, line and point sources. […]
Anno L - n.1 - gennaio/marzo 2017 Utilizzo di Tracker per lo studio della cinematica: un’esperienza in un liceo sportivo
An application of the Tracker Video Analysis and Modeling Tool software for the study of kinematics is presented. The activity has been tailored to exploit the students’ interest in sports, in order to improve their participation. The software has been used to make it easier to understand the basic concepts of kinematics, […]
