In 1995 two astronomers, Michael Mayor and Didier Queloz, detected around the star 51 Pegasi the first extrasolar planet, 51 Pegasi b. This is a giant gaseous planet, with dimensions similar to Jupiter, orbiting around a Sun-like star. Sofar, almost 4000 extrasolar planet have been discovered, and their number is costantly increasing. The refinement of observational methods and the development of space missions make the search for exoplanets – in particular of those which might have suitable conditions for hosting forms of life – one of the most exciting topics of astronomy. Most extrasolar planest weLEGGI TUTTO

Through this activity, you will be able to realize and light up your favourite constellation with Arduino. In order to reach this goal, we will use Arduino UNO, an hardware platform used to build up projects of robotics, electronic and automation, on which a software (in C language)  is installed, so as to allow us to check a series of sensors connected to the card itself, and interact with them. Over and beyond the Arduino card, we will need a series of leds of different colour – which will represent the stars ofLEGGI TUTTO

Through this activity, you will be able to discover how the variation of a magnetic field may produce an electric current, just as in the dynamo of a bycicle. To this aim, we shall use Arduino UNO, an hardware platform used in order to build projects of robotics, electronics and automation, on which we can upload a software (in C language), which will enable us to check a series of sensors connected to the card itself, and interact with them. In this project, Arduino will exclusively act as voltmeter o, allowing us to measureLEGGI TUTTO

Since many Italian schools are equipping themselves with 3D printers and the MIUR has financed these activities with dedicated calls, we thought it would be interesting to try to design and build a portable lunatario through digital fabrication. A lunatario is a large box, in our octagonal design, with eight holes to spy inside and a small moon hanging in the center. The boys observe this canned moon lit by a torch in one of the holes. The description of the possible explorations with the lunatic are described in thisLEGGI TUTTO

On clear nights with the new Moon, with the naked eye you can admire up to 3000 stars. The Ancients, in order to orient themselves in that myriad of bright dots, ideally connected the stars with imaginary lines, thus forming groups and giving life to fantasy characters and objects, around which they embroiered storied which were handed down from generation to generation. The sky areas identified by these star groupings are called constellations, which still help us understand the night sky, find interesting objects, and orient ourselves in space andLEGGI TUTTO

With this making lab, you will discover some aspects of light, while building a real scientific instrument – namely, a spectroscope. This is a basic astronomical tool, which allows us to study the chemical composition and the physical state of the celestial objects we observe. Obviously, the spectroscope you will build is not exactly like those used by astronomers in order to observe the stars, but it does work well, and will enable you to break down the light of surrounding sources into a rainbow of colours. You will discoverLEGGI TUTTO

Through this activity you will find out how much you weigh on the Moon and on the other Planets of the Solar System. During this activity we will use the Arduino UNO board. It is a hardware platform used to build robotics, electronics and automation projects, on which a software (in C language) is loaded that will allow you to control a series of sensors, connected to the board, and interact with them. In addition to the Arduino UNO board, we will use 9 buttons, one for each Planet of theLEGGI TUTTO
