IMBBC has implemented a series of Citizen Science campaigns targeting primary school kids in Crete during spring and summer 2022. Three primary schools, 9 classes and a total of 135 students were reached during the period of one month (10/5/2020 –8/6/2022). The events included lectures and presentations, field visits, beach cleaning campaigns, experiments in the class and hands-on experiences. All events were carried out within the framework of European Maritime Day – In My Country for the year 2022 and the activities of WP12 of the European project NAUTILOS.
