Chinese proverb says: 'A butterfly that flutters its wings causes a hurricane on the other side of the world'. That vision of the chaos shows the cause-and-effect relationship, which is well-observed in all areas of our life. The project entitled 'The Butterfly Effect' aims at showing our students that the development of the world is influenced by different ideas, inventions, actions that arise from curiosity, the need to solve a problem . It also proves that every action taken up has a meaning, and staying passive is not a good solution. We will think about what every person in the world is able to do; not just the big names who influenced the development of the world. Today those people are among the pantheon of personalities and they belong to the European and world heritage. Some of them did not realize the importance of their past activities. We will take into account contemporary events, anti-crisis measures, the division of the world's wealth, to think about what we can do in the environment in which the entity has little potential. Thus, even the smallest of our action, our protest, can form the nucleus of a significant change. The fact of participating in a project with such a large scale, establishing relationships with partners of different nationalities, exchange of experiences and views on the world, makes the project's participants aware that we all are inhabitants of Europe, of the world, and that our little "flutter of wings" does not remain unanswered and unnoticed.
