The Bl3u Water Club Edu kit is a collection of learning scenarios for ten teaching sessions implemented during the life cycle of the Probleu project at 3rd Primary School of Zografou, Athens, Greece. The lessons were delivered to a group of twelve pupils of 6th grade who were the members of the Bl3u Water School Club. The material produced during the implementation of the following plans were disseminated to partner schools and the experience lived by the teacher and pupils was discussed and exchanged within the framework of the collaborations established for this purpose. The reader is offered links to resources from various stages of our school’s engagement in a project which will be extended to the following scholastic years as the extensions and links to other school subjects are numerous.
