Anno XLVIII - n.4 - ottobre/dicembre 2015 Il Sistema Solare con gli occhi di Galileo
This paper deals with a didactic activity on astronomy carried out with a class of 13 year old students, during 2014-15 school year. The topic is the “Solar System” and hypothesis about its shape made through the ages by scientists from Aristotle to Galileo. […]
Anno XLVIII - n.4 - ottobre/dicembre 2015 Molle ferme e molle in vibrazione: qualche sperimentazione su elasticità e risonanza
This article reports about some experiments on the physics of resonance and elasticity. Employing a simple setup it is possible to identify the longitudinal eigenmodes of a stretched massive spring and to study their behaviour under the conditions of forced and damped motion. […]
Anno XLVIII - n.4 - ottobre/dicembre 2015 Il laboratorio Elettricità-Luce al liceo “Quadri” di Vicenza
This article describes a laboratory activity undertaken by a group of students in the final year of a scientific high school. The main goals were to clarify the relationship between the microscopic models and macroscopic aspects of electrical properties of matter and to examine the effectiveness of teaching based on guided inquiry. […]
Anno XLVIII - n.4 - ottobre/dicembre 2015 Nuove tecniche di analisi dei moti
This article describes a new method for studying motion, with characteristics similar to those of photo strobes. This uses a mobile phone, some free PC programs and a printer and can therefore be used in the absence of a true laboratory. […]
Anno XLVIII - n.4 - ottobre/dicembre 2015 È possibile sparare un proiettile attorno alla Luna?
If you were on the moon and tried to shoot a gun, would the bullet fire? And if so, in absence of air could an appropriate bullet reach a speed fast enough to orbit the Moon? Making use of considerations about mechanics, […]
Anno XLVIII - n.3 - luglio/settembre 2015 Esperienza con i raggi cosmici
The aim of this work is to show the didactic and scientific potentialities of the AMD5 detectors used in the ADA project (Astroparticle Detector Array)[1] for the introduction of cosmic-ray physics in the last year of Liceo scientifico. The dependence of cosmic rays on solar activity and atmospheric parameters were observed and interpreted. […]
Anno XLVIII - n.3 - luglio/settembre 2015 Misurare pi-greco
This article describes an activity aimed at measuring the value of pi. Five methods, were used, all of them easy to perform. All results agree with the known value within 1%. The activity is suitable to introduce the concept of measurement uncertainty at the beginning of Physics Classes. […]
Anno XLVIII - n.2 - aprile/giugno 2015 Metrologia e Correlazioni Quantistiche
Noise is unavoidable in measurements and limits their final precision. In particular, when quantization of carriers is involved, as for photons in electromagnetic fields or electrons in electric currents, a minimal noise is present: the Shot noise. Recently INRiM researchers have experimentally demonstrated how Shot noise can be beaten, […]
