The meeting was organized in Poland between 5th - 09th of September 2022. The aim of the LTTA meeting in Poland was to bring both teachers and students involved in this project together from 4 different countries in order to build a working team. During the process the team members discovered each other culture and specific habits making this a multicultural experience. The theme of C3 was “ WATER AS A LIFELINE FOR HUMANITY”. Before the meeting, the partners discussed and established the details in compliance with the communication plan of the project. The meeting programme was drawn up in such a way to find the meeting’s requirements and the project’s prerequisites. The participants built a deep understanding of the importance of the water and the way it is or can be used by humans. The produced material was uploaded on the gmail`s drive of the project.
