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 XLVI - n.3 - luglio/settembre 2013 Joseph Louis Lagrange a duecento anni dalla morte
The Piedmontese mathematician Joseph Louis Lagrange died in Paris 200 years ago. His interesting life and his scientific achievements are recalled and described […]
Anno XLVI - n.3 - luglio/settembre 2013 Un nuovo approccio all’ottica geometrica che mette in discussione la distinzione corrente tra immagine reale e virtuale
We here propose a new approach to the didactics of the so-called geometrical optics, an approach which is founded on an experimental basis and is useful in pointing out several common misconceptions. The main consequences of such a path are both the discovery of the real images formed by a plane mirror and the revision of the traditional notion of virtual image […]
Anno XLVI - n.3 - luglio/settembre 2013 Un esperimento per introdurre il caos deterministico nei licei
In this work it is shown how it is possible to build a simple device: the dripping faucet. This physical system exhibits an extremely interesting dynamic behaviour, useful to introduce the subject of deterministic chaos in high schools […]
Anno XLVI - n.2 - aprile/giugno 2013 La “Sala Giochi della Fisica” alla scuola “Cottolengo” di Torino
At the Cottolengo School in Torino (Italy) many pupils are foreigners and-or suffer a disability. We implemented a set of “play booths” with the purpose of motivating and encouraging the pupils’ interest in science and promoting aggregation and cultural integration […]
Anno XLVI - n.2 - aprile/giugno 2013 Acustica con una Bic e uno smartphone
A smartphone, with its integrated sensors and CPU, can aid experiments in many different areas of physics. We show how the resonant frequencies of a pipe can be measured using a smartphone and a Bic pen […]
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 […]
