The project involves very young students and focuses on the change of climate due to sea pollution. Through different activities and including all Primary subjects students will learn more about the topic moving from a study of sea environments to the issues caused by pollution and their consequences . The transnational collaboration will add value to the activities through effective collaboration that will lead to share experiences, to practice new activities such as comparing the sea environments in the different partner countries, giving the pupils the opportunity to know other seas of Europe through the eyes of students who live there. At the end students, teachers and parents will be more aware of the rules to follow to protect the environment and that “will allow the present generation to satisfy their needs without compromising the ability of future generations to satisfy their own”. The partnership will determine a list of rules to help reduce sea pollution.
