Hands-On Climate: Engaging the Public with 3D Geo-Data

Despite the abundance of data on climate change, there remains a significant gap in public awareness and action. Recent trends in data communication have introduced the concept of data physicalization, which transcends traditional written and visual methods by engaging multiple senses, including touch and hearing. This innovative approach has shown potential in reaching diverse audiences and enhancing public engagement.

Our project, "Tangible Statistics" at IIS Cavazzi (Liceo scientifico), involved students aged 16-18 and demonstrated the successful impact of data physicalization. A key method employed was the translation of geolocalized data into 3D models using QGis, followed by 3D printing. This technique was showcased at Science on Stage Italia in Naples (September 22-24, 2023) and has proved applicable also to younger students as it was immediately replicated in a junior secondary school.

The project utilizes freely available tools such as QGis, Blender, FreeCad, and Cura for slicing. Training students in these tools, specifically for model creation and printing, is efficient (approximately 4 hours of lab work plus home application). This investment enriches curriculum across diverse subjects, facilitating the study and dissemination of data related to geography, environment, and more together with fostering data literacy of future responsible citizens.

Environmental monitoring data, such as extreme temperatures, precipitation, and fire risk indices, are particularly suitable for this technique. Beyond presenting raw data, the focus is on narration– a critical factor in making data resonate with the public. The creation of physical artifacts for storytelling enhances public exhibitions, outreach, and awareness campaigns. These artifacts foster emotional engagement in an otherwise distracted or statistically unskilled population. The tactile experience of touching these models enables deeper understanding and accessibility of complex data.

Moreover, these models, either scanned from the artifact with a cell phone free app or directly produced in digital format, can be integrated with data journalism pieces through QR codes. This integration allows readers to engage with augmented reality models while reading, providing a hands-on experience of data manipulation.

The potential of data to bring people together to address societal issues is huge. By understanding and improving our communities through data, we can spark civic dialogue, hold institutions accountable, and foster effective communication. Our project is a contribution in demonstrating that through creative data physicalization, we can transform the abstract into the tangible, making climate data more accessible and impactful for the general public starting from Education.
