    Description: We present calculations of the early stages of the formation of Jupiter via core nucleated accretion and gas capture. The core begins as a seed body of about 350 kilometers in radius and orbits in a swarm of planetesimals whose initial radii range from 15 meters to 100 kilometers. We follow the evolution of the swarm by accounting for growth and fragmentation, viscous and gravitational stirring, and for drag-induced migration and velocity damping. Gas capture by the core substantially enhances the cross-section of the planet for accretion of small planetesimals. The dust opacity within the atmosphere surrounding the planetary core is computed self-consistently, accounting for coagulation and sedimentation of dust particles released in the envelope as passing planetesimals are ablated. The calculation is carried out at an orbital semi-major axis of 5.2 AU and an initial solids' surface density of 10/g/cm^2 at that distance. The results give a core mass of 7 Earth masses and an envelope mass of approximately 0.1 Earth mass after 500,000 years, at which point the envelope growth rate surpasses that of the core. The same calculation without the envelope gives a core mass of only 4 Earth masses.

    Description: Scientific exhibitions, hands-on laboratories for kids, meetings and seminars with researchers, guided tours to laboratories are the ingredients for the outreach week "ScienzAperta" at Istituto Nazionale di Geofisica e Vulcanologia (INGV). ScienzAperta, the Open Science Week, responds to the needs and the request of the society for more information on issues regarding our Planet. The common goal is to engage INGV researchers to be involved in a correct, straightforward and efficient communication to public about research and technological innovations they perform. In a world that request citizens to be more informed, aware and able to make crucial decisions about their own health and safety, the knowledge is crucial to handle doubts and to know how to choose with consciousness. Since 2011, ScienzAperta held once per year during spring; several INGV headquaters over the Italian territory open their doors to public. The goal is to help raise awareness about earth sciences, and research activities at INGV, as well as intrigue, interest, and stimulate audiences of all ages. Researchers and technicians involved in outreach activities conceive scientific programs to present research as the heritage of all. Some activities were organized in collaboration with other institutions and with transdisciplinary approaches. For example in 2011 edition, in collaboration with Istituto Nazionale di Ricerca per gli Alimenti (INRAN), geophysics and nutrition sciences were linked through geodynamic evolution and diet evolution of the Mediterranean. In all the past three editions music-based initiatives were designed to attract young people as well as generic public, such as the performances "seismic waves, sound waves, from earthquake to music", "musical journey of Italian earthquakes", "waves, sympathy and music", "landscapes, territory and wines". The ScienzAperta programs were designed giving special attention to pupils and teachers. Hand-on laboratories for kids on earthquakes, volcanoes, and also on INGV researches in Antarctica were organized, and achieved great participation and appreciation. Analysis of questionnaires distributed among adult visitors and children during an Open Saturday in 2013 in Rome provided hints to improve the outreach event format. Acquired pieces of information were perceived as useful to get more in depth with the topics by mostly all adult visitors; nothing was perceived as not clear, appreciation comments came as well as invitations to repeat such events more frequently; children perceived the games as very interesting, very useful and well organized, but in some cases the notions not so easy to be understood.

    Description: Italian primary schools participated with enthusiasm to the drawing competition “I'm a scientists too! Science and scientists from the children point of view” organized by the Laboratorio di Didattica e Divulgazione Scientifica of Istituto Nazionale di Geofisica e Vulcanologia in Rome, Italy. The best drawings were awarded and published in the 2011 school calendar. Children were asked to realize a drawing, choosing among three suggestions: 1) How do you imagine a scientist and how do you imagine the daily activities of a researcher? 2) What invention do you consider the most important among all those you know? 3) What would you invent? The topic “invention” (#3) was the most successful. In fact, among the collected 1,000 drawings, 400 drawings depict scientists, nearly 150 depict scientists with their inventions, and other 350 depict inventions alone. A classification scheme was designed in order to synthetically describe this set of images and analyze it. The Draw-A-Scientist scheme, known from literature, was mantained but modified in order to characterize both inventors and inventions. As regard scientists, a preliminary analysis reveals a persistent gender stereotype, since most of depicted persons were male and nearly half of girls draw men scientists. The image of “mad scientist” is still present but it is mainly related to men. Women scientists are drawn by girls; they are represented as young, not crazy, usually good-looking. There are no particular differences between boys and girls in assigning research fields to scientists. Women scientists are often depicted as assistants, but when alone they are self-confident enough to give their name to an invention or to aspire for Nobel Prize. In this work we present the preliminary analysis performed on drawings containing inventions. What do girls and boys 6 to 11 years old invent? Robots, helping in housekeeping or in doing homework; rockets, space vehicles and time machines, but also fictional machines and hybridized animals, devices helping in human caring or having impact on the environment for a better quality of life. In general, the preferred subjects refer to something useful with respect to things we do in everyday life but also fancy devices, for which imagination runs wild. Inventions can include something useful to individuals or to a community, being something totally new, or already existing, but improved, combined or transformed; being a device or part of the natural environment or of the human body; they can involve several dimensions of living, like eating, transporting, entertainment, work. Do girls and boys conceive different inventions? What do they invent with respect to the Earth Sciences and natural environment? Which are the relationships with the outreach programs organized and performed by INGV?

    Description: The Istituto Nazionale di Geofisica e Vulcanologia (INGV) is currently the largest European scientific institution dealing with Earth Sciences research and real-time surveillance, early warning, and forecast activities in geo- physics and volcanology. The Laboratorio Didattica e Divulgazione Scientifica of INGV organizes every year educational and outreach activities with schools of different levels and with general public to convey scientific knowledge and to promote the Research on Earth Science, focusing on volcanic and seismic hazard. Among the most successful initiatives is the creation of a calendar designed for the schools and realized based on a competition devoted to children of primary school. The intent is to provide a pleasant stimulus for discussion for teachers and students. Schools participate with enthusiasm by sending drawings made by children on a specified theme, different each year, chosen among geophysics and earth sciences arguments. For 2011, the theme was selected also with the aims to investigate on the image the young generations have of the Research and on its potential and future prospective. The title was “Scienziato anche io! La Scienza e gli scienziati visti dai bambini” (I’m a scientist too! Science and scientists from the children point of view), with the purpose of give a shape to the image children have of the world of science, its potential and the figure of the scientists. We asked the children to realized a draw suggesting some possible arguments between: 1. How do you imagine a scientist? How do you imagine the daily activities of a researcher? 2. What is the invention you consider the most important among all those you know? 3. What would you invent? The 986 drawings realized by 6 up to 10 years old boys and girls from 48 schools distributed throughout the Italian territory, report us a generally positive picture of the work of scientists and also highlight a great level of confidence in the potential of science, capable to respond to needs and problems of the humanity and of the environment in which we live. Moreover, the drawings provide us a direct and unconventional approach to point out how we convey the scientific research (a strategic topic for a suitable future of the humanity) to the players of the world of tomorrow.
