Ins Valèria Haliné is a Spanish secondary school located in the south of Barcelona and just 15 minutes walking distance to the sea. This great location led us to promote diferent activities related to water or the coastal environment throughout the years. Being aware of these diferent activities promoted by fiferent subjects and teachers we decided tot put them together as an interdisciplinary school project.
The project has a clear contact with different institutions and take students outside the school to undertake their a fieldwork. List of activities:
-Seawater: Students collect a seawater sample and measure its temperature, salinity, and pH to understand how these factors influence marine environments. Using thermometers, hydrometers, and pH meters, they record and compare results with freshwater data. This activity develops skills in accurate measurement, data recording, and analysis. Students learn to handle scientific equipment safely, interpret results, and discuss how environmental conditions affect the physical and chemical state of seawater. 3rd ESO (14 years old)
-Microplastics: Students collect and filter water samples to identify microplastics under a microscope. They record and analyze data, developing observation and analytical skills. The activity raises awareness of plastic pollution and encourages solutions like reducing plastic use and improving recycling practices. 3rd of ESO.
-Freshwater: Along with Associació Habitats (https://www.associaciohabitats.cat/) Students collect river water samples to measure temperature, pH, and turbidity. They analyze results to assess water quality and ecosystem health, developing skills in sampling, measurement, and data interpretation. (4th ESO (15 years old))
-Beach dunes conservation: Students work to remove invasive plant species from beach dunes and monitor vegetation recovery. They develop skills in observation, teamwork, and environmental stewardship. The activity teaches the importance of protecting native plants, preventing erosion, and maintaining dune ecosystems. (4th of ESO)
All results are shown around 22nd March World Water Day.
