The "Water day 2019 & Earth Day 2020” Erasmus+ project will involve six schools in five different countries. We chose the universal topics of Water and Earth to raise awareness about significant issues we face in the 21st century. These represent new challenges in education. At the end of each school year, their collaborative work will culminate in a big cultural event, as each of the six schools will organise Water Day in 2019 and Earth Day in 2020.
