Motivation: There are many reasons to justify our interest in this project. We are the only school of the project located in a +1M inhabitants city, which is especially remarkable for these studies since more than 70% of the world population is estimated to live in cities by 2050. Madrid is a big city that is tackling deep problems and challenges related to mobility, consumption and lifestyle, and their consequences on environment, health and wealth. For example, every year we suffer traffic restrictions since high pollution levels are frequently reached. Political decisions to improve our quality of life will inevitably yield economical side effects that may stress vulnerable families like the ones that we assist. Our student’s profile document states that we work to achieve ‘citizens with ecological awareness committed to the care for our Common Home’. We believe that this project may be a call for, as Pope Francis says, ‘an inclusive dialogue about how we are shaping the future of our Planet’. Key people: English and Science teachers and board members, with experience in coordinating or participating in KA1/KA2 projects. In case of some of the key people leaving their post during the project, their replacement will also take over their role. Experience and expertise: The school has a great technical experience: most of our teachers have a highly developed ICT competence, using ICT as an everyday tool and it also counts on a team of Physics, Chemistry and Biology teachers that can be responsible for the explanation of the scientific aspects of this project. Our 3rd ESO students delve into the Encyclical, Laudato Si, on environment and ecology. In addition to this, we have succeeded in some economic contests, e.g. winning the 1st prize in an ESIC competition in June’18. Our school devotes a good amount of time and resources to helping our students understand the environmental and economic challenges we face. Proof of this are projects and activities such as the design of their ideal town from the point of view of sustainability; activities of identification and study of different ecosystems; knowledge of water and waste treatments. We collaborate with external agents in projects for the reuse and reduction of consumer goods, such as ‘Bikes for life’ of the Alberto Contador Foundation and in a charity project to recycle plastic lids. We promote a comprehensive school approach to European Projects. We have taken part in several E+ Projects since 2014: EDUrope, MINFEducation (both KA1), Welcoming Diversity at School (KA2), E+ Essen Conference. So we have a large European team that works cooperatively on achieving our goals.
