The Banc de Sang i Teixits de Catalunya has conducted the project “Donació de Sang i educació per a la ciutadania” that aims to involve young children and minors in the task of spreading the need to donate blood. Thus, young people learn content related to blood donation and communication aspects, while promoting health in their environment. In addition, it is established a connection between school and outside school contexts that allows to work content though a real learning and service experience. Sant Andreu de Natzaret school has been one of the education centers that participated in this project.
