"""In 2015, UN Member States joined forces to adopt a total of 17 ‘Sustainable Development Goals’ acting to end poverty, protect the planets and improve the lives of everyone all over the world. There is a dire need to get the word out, create awareness and encourage people to take action! With this in mind, educators all around the globe have the mission of raising conscious humans in order to ensure a livable world. We consider that this topic is of major importance for the wellbeing of people around the world and can only be achieved by educating both teachers and students towards the necessity of respecting these goals. Therefore, while the ‘Sustainable Development Goals’ established by the UN covers a wide range issues in need of urgent action, the current project will primarily focus on creating small scale clean affordable energy and establishing sustainable forms of agriculture that may be replicated in the partner schools’ communities. The main purpose of this project, titled “Act Responsible, Think Sustainable”, is to use education as a tool to generate awareness on two issues prevalent to the earth through the creation of a self-sustaining ecosystem within each school. In long term, the project aims to improve the students’ actions to support sustainability in the participating countries, in the local areas of the partner schools, and to have trained teachers who can continue and perfectionate the education of sustainability, by introducing the topic in the curriculum is each school.The project is carried out by six partners from Germany, Italy, Spain, Hungary, Portugal and Turkey. The partners are primary of middle schools and they all have a certain degree of experience on this topic as part of their curriculum or as extra curricular activities, which helped us to build on our previous knowledge and perfect this theme, through the exchanges of good practices. The exchanges were done both virtually and also through a number of six short-term exchanges of groups of students in each participating country. The project involves a total number of 650 students, aged between 11 to 14 years old, a number of 50 teachers. In addition to this number, many other teachers, councilors, local representatives, and institutions that support sustainability will work on the implementation of the activities and learn from our results. Parents will also directly involved in this project as they will participate in environmental activities organized in each school. The project focuses on several of the most prominent ‘Sustainability Goals’ declared by the UN. . The goals we are focusing on are: Affordable and Clean Energy, Sustainable Cities and Communities, Climate Action, Life Below Water, Life on Land and Clean Water and Sanitation. Each partner was responsible for one of these aims and created innovative methods to implement them on a school level, adapted to the students’ age and capacity. All the activities are based on an interdisciplinary approach, in order to support the teaching of these sustainability goals in the most effective way. We mainly used innovative and motivation methodologies to stimulate the students interest in this topic, such as STEM methodologies, collaborative and peer learning, learning by doing, learning through experiments, leraning in nonformal environments, and many ITC tools.The final product resulted from this project is a small scale sustainable ecosystem built in a greenhouse, which will not only be a real example of what sustainability mean, but also a legacy and a teaching aid for all the students in the partner schools even after the end of the project. The greenhouse will not only be used for this purpose, but also for other educational purposes, to teach the students the way food is produced, and limit the waste of consumerism.The main benefits resulted from this collaboration is learning and sharing innovative educational methods and approaches to teach sustainability in schools, engaging the cooperation of teachers and students from European schools, development of teacher’s and children’s digital skills and the use of ICT, development of teacher’s educational and language skills. Etinning platform played a great role in the development of the project, before during and afte its’ completion. All of the Erasmus partners worked on an eTwinning project together, called ""The Real Green Deal"" (211263). The eTwinning project was the space where the partners first got to work with each other as a team. The project was used to create student's background for our project. The eTwinning platform is also used for the dissemination of the project's results, for the project management meetings and as a safe place for the students to connect with each other virtually.As a conclusion, we believe that by implementing this project, we changed the students attitude towards the need of sustainability, and the results will be seen in their daily life actions in the near future."
