25th November was an important day for My Water Footprint eTwinning project. Since March 4 partners have been invited to share their experience while working in the project in various online sessions with other European teachers, students and education stakeholders. All that led to the First Education for Climate Day that took place on 25th November. On that day a lot of things happened, among them the Education for Climate’s collaborative online platform was launched. What’s more, Iva Naranđa, Stavroula Skiada and Justyna Plota, were chosen to be speakers during HACKATHON - First participatory community challenge and to present their challenges which they faced while conducting the project work. The problem that was chosen to be solved during the hackathon made all the meeting members brainstorm and share possible solutions they came up with. This way we could see that collaboration and cooperation are extremely powerful and if we do things together, there seems to be no limits.
