The project will stimulate the student's awareness of sustainable development through the use of renewable energy sources and conscientious energy use. It will also explore and familiarize the energy situation in the world, Europe and Croatia, provide an overview of energy resources, their use and their constraints.Nikola Tesla was a citizen of the world - so is a great contribution to humanity. He actually marked the beginning of global electrification of the planet. He was a great ecologist, very concerned about the fact that people are spending too much on the resources of our planet, which has been fueled by renewable sources of energy. Therefore, we decided to dedicate the project to the scientist Nikola Tesla, his life, work and inventions. It will be another way of linking the content of physics, energy, electrical engineering and ecology. The aim of the project is to acquire skills and key competences using digital technologies and tools, and is planned to be achieved through the processing of environmental and renewable energy sources. Through teaching and project activity students develop different types of functional literacy and build personal and national identity. This goal is to bring students closer to self-learning activities - collect, choose and process data, think, conclude, discuss and present the most impressive way of teaching, take care of the time that you have to be interesting and compelling. Project activities can be carried out within the teaching of physics, energy, ecology, electrical engineering, foreign language and information technology. The age of the students in project is 15 to 17 years.Education and co-operation will be realized through the search and creation of films on power plants and renewable energy sources, the development and exchange of digital content through web 2.0 tools (quizzes, presentations, online games, brochures). Through our transnational partnership, we will also cooperate with local associations and educational institutions. The project will enable the expansion of knowledge from the STEM area, and enhance motivation and interest. Through the use of IT tools, students will develop digital competencies, critical thinking, and problem-solving skills. Along with the development of communication skills and teamwork, they will have the opportunity to experience intercultural environments and to get to know different cultures, as well as to improve the knowledge of English in real-world situations. With the development of self-confidence, students will develop awareness of ecological problems and the importance of their solution.The workshops will make it possible to popularize the teaching of natural sciences through experiments and independent research, to encourage and develop the interest in studying science, to enable students to better understand the nature of natural and physical legacies. The research type of teaching will be popularized, the development of independent access to scientific content as well as the interest of research work. The project will boost the interest of young people in science and careers in science. It will increase the interest of students for the STEM and ICT group of subjects, increase their success at state maturity and increase the number of students enrolling STEM and ICT studies and hence their employability. With this project we want motivate students to access more difficult subjects (eg physics, electrical engineering, energy, foreign language). We want to design new learning patterns to facilitate the learning process and reduce the dropout rate. Through the project we will show a practical link between some theoretical themes and reality, develop skills such as teamwork, adaptability, mental agility, problem solving. We will implement communication skills starting from the basic understanding of all partner languages; promote education-oriented, student oriented and relevant to everyday life-based education. By project we make teaching of physics, science, electrical engineering, energy, business studies and foreign languages in secondary schools more accessible, more interesting and more applicable. We share our best practices, strengthening cooperation between high schools and institutions important for energy and ecology and exchange of good practice at European level. We expand the potentials of social networks (Facebook, Twitter ...) and platforms (eTtwinning, Google apps) for teaching, sharing and learning. Open educational resources as a result of our project will be available on the project website and can be used by other schools as well. The project will result in new extracurricular activities in the field of ecology and energy. The results of this project will be incorporated into the strategic and development documents of the institution.
