Harnessing Open Data in Classroom: Fostering Water Literacy

This poster presents the integration of Open Data into secondary education through an innovative educational intervention focused on water quality monitoring in Greek rivers. It leverages real-time physicochemical data -such as pH, temperature, dissolved oxygen and conductivity- from the sensor network operated by the Hellenic Centre for Marine Research (HCMR), part of the national monitoring efforts.The worksheet engages students in analysing visualised time-series data from river stations, starting with parameter interpretation and progressing to correlation analysis.Implementing this educational activity in class enhances student’s data literacy and critical thinking by enabling analysis of authentic research datasets, bridging theoretical knowledge with real-world applications. In addition, cultivates environmental awareness and water literacy, empowering students to evaluate river health and advocate for sustainable practices using evidence-based reasoning.
