Nowadays nobody can deny that our planet is going through an environment and climate change. We, as educational institutions (Bulgaria, Romania, Poland, Greece and Spain), are extremely concerned about our responsibility towards this situation and aim at raising our students’ awareness about it. Hence, we truly believe that our project will highly contribute to this purpose. The main objective of our project is to make our students conscious of the need to take care about our environment and its sustainability. This will be done through a common thread: a natural park research. This main task along with others will contribute to achieve these objectives: foster key competences for lifelong learning; raise awareness about environment and current climate emergency; improve linguistic and ICT skills; increase knowledge of environment and legal terminology; raise awareness of our natural heritage; highlight democratic participation; develop ability to take initiative, problem solving, collaborative work; boost European citizenship feeling; increase knowledge of European legislation on natural environments protection; foster critical thinking; showcase recycling and reusing.Our selected priorities are: Environmental and climate goals; Common values, civic engagement and participation; Social and educational value of European cultural heritage. Our objectives are directly linked to them as the main one is make our students conscious of the need to take care about our environment. We also mean to create common values by developing the feeling of European citizenship. Finally we aim at sharing our European heritage by getting to know our natural parks.Our project is mainly addressed to pupils (from 15 to 17) because its objectives mostly focus on them. Five students and two teachers from each country will participate in each mobility. However, the project is designed to involve a wider number of participants. As there will be activities before, during and after mobilities, a great number of participants will be able to participate, and most activities will be integrated in normal lessons. Besides, through eTwinning, the project will be accessible for all participants. The managerial staff will also be involved, supporting project management aspects, mainly. Concierges or administrative staff will also get involved in some stages of the project. Another important group of participants is the families. They will be informed and get involved from the very beginning, as they need to know all projects’ aspects deeply so that they are confident to let their children participate. Finally, we will count on other local participants: authorities, experts, media…There will be a leading activity for each mobility, along with minor tasks. For C1 a research about a natural park will be done. During each mobility we will hike in the natural park chosen by each country. For C2 we will investigate on the European legislation on natural parks and check whether it is applied in each country. To improve knowledge of environment and legal terminology, a multilingual glossary on this topic will be made. The next step will be to agree on a list of commandments for sensible behaviour regarding our natural surroundings and environment sustainability (C3). We will also focus on the importance of recycling and reusing our rubbish by making a piece of art of recycled material. For C4, we will have a meeting with the staff in charge of managing the natural park so as to find out what is done for its promotion and maintenance. For C5 we will record a short film to raise awareness about the need of sensitive behaviour towards our environment and the sustainability of our planet, and design a contest to check how much we have learnt.For project implementation active learning methods will be applied: collaborative work, task and challenge based learning, peer learning, critical thinking and problem solving tasks…All activities will end up in tangible and intangible results. There will be digital documents with the research of each natural park and photo album of the visits. We will record videos of the meetings. A digital multilingual glossary will be produced. We will keep record of each activity, which will be shared mainly in eTwinning. Regarding intangible results, our students will be more aware about our planet, more motivated to speak English…Considering the aims and planned activities of this project, a considerable beneficial impact is expected on all participants. At the end of the project the experiences and insight gained will continue to be used by all target groups. The institutions will use them in further projects. The schools will continue to use the products and benefit from them as part of our school routine. The project results will be active on dissemination platforms and developed with further experience. Pupils will broaden their mind as European citizens and grow as human beings with critical and conscious thinking.
