Anno XLIX - n.3 - luglio/settembre 2016 Ottica geometrica rivisitata
A simple and intuitive model of the functioning of mirrors and lenses is proposed. This model could profitably integrate the traditional way of teaching this topic. The purpose is to make it more effective by giving students a physical interpretation of the way these devices affect light beams. […]
Anno XXIX - n.1 - gennaio/marzo 1996 Ottica non lineare-ottica bistabile
We think it worthwhile to publish this examination for various reasons. Besides comparing content and difficulty degree of our national tests with those of other EEC countries, one can also deduce informations about different teaching strategies. Once more the test evidences the importance given, […]
Anno XLIII - n.1 - gennaio/marzo 2010 Paradossi del Geomag
Using iron filings and the well known GEOMAG magnetic toy we build and demonstrate unusual and interesting magnetic fields. […]
Anno XXXVI - n.2 - aprile/giugno 2003 Passaggio della luce attraverso un pacchetto di lastrine
The article describes an experiment on the absorption of light through a pile of sheets of Perspex or glass. The experiment, in itself simple to perform, lends itself to a rich conceptual analysis and introduces a discussion of some aspects of the scientific method and of the search for physical laws. […]
Anno XLI - n.2 - aprile/giugno 2008 Pendolo con piano di oscillazione inclinabile
This teacher-designed device was used by 14 year-old highschool pupils who already knew how the period of oscillation of a pendulum depends on its length, with the purpose of finding its dependence on the acceleration of gravity. The pupils processed the experimental data with the help of a worksheet on a PC. […]
Anno XXXI - n.1 - gennaio/marzo 1998 Pendolo di Foucault in miniatura da esposizione
A 3.5-meter long Foucault pendulum is realized for teaching and exhibition purposes. The pendulum operates continuously without need for maintenance or external control. The decay of the oscillation amplitude due to friction is compensated by the application of a pulsed central magnetic force, […]
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, […]
