Anno XXXV - n.4 - ottobre/dicembre 2002 Algemeene Natuur Wetenschappen (ANW): un nuovo corso per la comprensione pubblica della scienza nelle scuole secondarie superiori a indirizzo generale in Olanda
Introducing another subject in the school curruculum is a delicate affair, especially so if the subject is totally new. This article describes the birth, first implementation and encountered difficulties of ANW (Public Understanding of Science), a new subject intended for all the students of the Dutch general upper secondary schools, […]
Anno XXXV - n.4 - ottobre/dicembre 2002 Il suono del moto
How could we listen to the sound of motion? We did it, during an evening at school devoted to Galileo, using easy-to-find materials, such as fishing-rod bells and a metal upright from a set of shelves as an inclined plane. […]
Anno XXXV - n.4 - ottobre/dicembre 2002 Anemometro per CBL
Modern portable data acquisition systems (RTL) allow easy performing didactical experiments on environmental sciences and metereology. This simple anemometer, added to exhisting thermometer, barometer, and hygrometer, offers the possibility of using a simple and cheap portable meteo-station. […]
Anno XXXV - n.4 - ottobre/dicembre 2002 Realizzazione di un anemometro a basso costo a scopo didattico e sua taratura con un pendolo fluidometrico
We propose here a simple realisation of an anemometer, using recycling materials (except for a small milliamperometer). The calibration of the instrument was obtained by means of a ‘fluidometric pendulum’, following the idea proposed by the great hydraulic engineer Domenico Guglielmini (1655-1710) at the end of the 17th century. […]
Anno XXXV - n.4 - ottobre/dicembre 2002 Un’esperienza interessante in 1ª C¹ ovvero le straordinarie virtù di una molla giocattolo
Several experiments with the Slinky lend themselves to an analysis in terms of energy that is rigorous and easily comprehensible at the highschool level. […]
Anno XXXV - n.4 - ottobre/dicembre 2002 Radiografie fatte con un orologio
Beta and gamma rays are able to penetrate into solid bodies. This property of radioactivity can be verified in a very simple and efficacious manner, making an experiment, even in a school laboratory, with poor matter. […]
Anno XXXV - n.3 - luglio/settembre 2002 Un modello fisico: il lago ghiacciato
We have created and studied a model of the cooling and freezing dynamics of a lake when outside temperatures are below 0 ºC. […]
