Climate change has become an important theme that will have consequences for present and future generations. Air pollution is an important theme that influences our lives. Antwerp and Turin are both historical cities dealing with the same sustainability-concerns and are confronted with a problematic quality of air caused by urbanisation, traffic, port or industry. In both cities the limit values set out by the WHO are exceeded. Air quality research is largely limited to specialised investigative bodies and universities. With this project we want to learn students to perform a scientific research using different methods of measuring of air quality. We want them first to investigate and then to draw conclusions about sustainable life choices concerning air quality. We want to raise their awareness of the issue. Sustainable living in current city life is a project that aims to make 2 groups of students acquire skills and European Key competences, more specific STEM, competence in science and citizenship, competence in citizenship, competence in language and personal, social and learning competence. The first group are 15 students of Liceo Galileo Ferraris. The liceo is a competitive school, with this project the school wants to give students who haven’t joined any project the opportunity to do so. The second group are 15 ASO and TSO students of Moretus Ekeren,. We want to use the unique opportunity to not limit our project to the ASO or CLIL-students only. Moretus Ekeren is more experienced in competence-oriented learning whereas Liceo Galileo is more experienced in STEM and lab-analysis. Both school teams are eager to learn from each other. The outcome on the level of teachers will be a guide on competence-based evaluation. To achieve these objectives selected students will work together via eTwinning during the whole project, but we also plan two mobilities, in Nov19 to Turin and in Apr20 to Belgium. These mobilities will enhance the student’s social skills, first they work in team all through the project, secondly they are divided in host families during the mobility. English as a lingua franca will be a vital tool to communicate with each other about their research results. During the mobilities we introduce them to reciprocal methods to measure air quality and possible ways to ameliorate the situation in both cities. In Turin the students, divided in small groups, will work on the design and implementation of a monitoring survey of air quality using both biological and chemical indicators. Chemical data will be collected through wearable devices (AirBeam and AirCasting) for the sampling of, respectively, NO2 and PM 2,5. These wearable devices will be programmed on an Arduino programmable board and built with a 3D printer by the Italian students. In Belgium the students will work with the methods of Airbezen (strawberry plants) and CurieuzeNeuzen. On the last day of the exchange the students will complete a city rally with a visit to the eco-house and observations of policy decisions will be made (sharing mobility, Park Spoor Noord, green roofs).The comparison between the two cities leads to a list of good practices to be communicated with the local council in a letter. Before, after and during the mobility the findings will be disseminated in both schools. In Sep19, and again in Sep20 students will investigate the impact of the project through Straatvinken@school, counting the mobility choices of the people at school and the visibility on bike. We will cooperate with civic movements such as Ringland Academy, Torino Respira, Cittadinanze per L’aria and governmental institutions such UA and VMM. They will provide us with guest speakers during the mobilities and the Scientific Symposium. The students will use what they have learned and investigated to ameliorate their answer to their research question. The result will be presented with a scientific poster and a presentation. In Turin on the Science Fair, in Belgium on the scientific symposium. The aim is to empower students to communicate accurately about the problem, to know possible solutions and to recognize suitable policy decisions. After the project the students will have enhanced their ability to act as responsible citizens and to participate in civic life based on the understanding of sustainability. They will understand science as a process for the investigation through specific methodologies including observation and controlled experiments. They will be able to express their ideas on the subject fluently in English, finally they will have learned about international group dynamic and taking their responsibility as a social being in an learning environment. After this year of student exchange we wish to continue cooperation between both schools, we would like to apply for student’s exchange partnerships KA229 that enables students to study in partnerschool for a longer period and eventually the teaching of training assignment.
