Anno L - n.1 - gennaio/marzo 2017 Alcuni strumenti utili per esperimenti interessanti
Some simple, low cost and useful apparatuses are described which are easy to be made, even as homework by students. Their usefulness will be found in a number of experiments which normally require expensive and not commonly available instruments in the school laboratory. […]
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 XLV - n.2 - aprile/giugno 2012 Alla ricerca delle cause del recente riscaldamento globale
2012 is the ‘International Year of Sustainable Energy for all’ but most of the energy we use comes from fossil fuels. We know that increasing the amount of CO2 in the lower atmosphere can trap infrared radiation, increasing its temperature. Climate change has always been a result of natural causes, […]
Anno XXV - n.4 - ottobre/dicembre 1992 Allestimento di una piccola stazione meteorologica dotata di psicrometro on-line
A simple meteorological station, connected on-line to a personal computer, was used by first-year students of physics at the University of Bologna. It gave the students the opportunity to: (i) work with an example of a technologically up-to-date system for data acquisition, […]
Anno XXIX - n.2 - aprile/giugno 1996 Amplificatore di condizionamento per Universal Lab Interface
The cheap circuit here described makes possible to process signals in an arbitrary range (e.g. ± 10V) without an external supply, using the positive supply (+5V) available on the U.L.I. interface connector. […]
Anno XXV - n.1 (Inserto: Il laser nella didattica) - gennaio/marzo 1992
Anno XXXIV - n.1 - gennaio/marzo 2001 Analisi del funzionamento di un orologio ad acqua
In this paper the author presents a discussion of the characteristics of a simple water clock built with a tin. Starting from experimental measurements, the emptying of the tin is theoretically described as a simple exercise. The theoretical result is tested on the experimental data and then used as model for the discussion. […]
Anno XXXVIII - n.3 - luglio/settembre 2005 Analisi del vento rilevato da una centralina meteo
The students of a vocational school installed a meteorological station and measured and studied the pattern of the winds. The activity proved to be a valid didactic experience with a scientific fallout because these were the first known data about the wind in the surroundings. […]
Anno XXVIII - n.1 - gennaio/marzo 1995 Analisi della velocità di propagazione di un impulso termico trasmesso per conduzione in un metallo
In this paper we are dealing with the phenomenon of propagation of a thermal pulse in solid metals. We are comparing results drawn from a mathematical model with data measured by connecting temperature probes to a computer on-line. […]
