The scientific discoveries gained over the last 70 years now allow us to build a unitary history of the universe that gathers the contributions of many disciplines. These new vision assigns to the Earth Sciences a new and important role to promote the convergence of many disciplines in order to build a unified history of the universe and of man in it. An example of this new role can be found in the Alternanza Scuola-Lavoro ASL (combined experience of study and work). For the Liceo the ASL, is a challenge. It risks becoming another activity that is added to citizenship education, assessment by skills, university orientation. The teachers see this set of activities as an already inadequate subtraction of time. Interesting opportunities are created by engaging students and the whole class council in activities of contextualization of knowledge. Students, with a precise responsibility in a working group, experience some of the typical dynamics of a work situation. From the observation, guided by indicators, and from the evaluation of the products, the teachers can obtain useful indications for inserting the students in the business realities. The Big History Project in Earth\u2019s Science context can be the solution. The students, in groups, study the history of the Universe according, they will have the task of creating a product of their choice. \u201cAvogadro Institute\u201d of Biella has produced videos with Sony Vegas Pro.
One has engaged in a History of the Universe in 8 minutes, the other has presented the geological history of Biella. This job could be preparatory to a subsequent ASL in a geopark. In the \u201cA. Banfi\u201d Liceo in Vimercate (MI) it was decided to let the whole class work in the realization of a single product as 30-minute documentary that obtained almost 1500 views on Youtube. An educational trip to the Geological Observatory of Coldigioco has introduced students to the complexity of the geological history of Italy and the international interest it raises. A subsequent inspection in Val d\u2019Ossola, led by the Department of Earth Sciences of the University of Milan, provided the necessary information to relate the remote history of the valley with the recent one.
The online attendance of a coding course allowed students to design and implement an application for mobile phones with App Inventor. From the set of evaluative elements such as group work observation tables, the daily report of the progress of the activities on a dedicated platform and the evaluation of the realized products, a profile of the student\u2019s skills can emerge, useful for a subsequent ASL insertion in a company real and also for orientation at the end of high school studies
