The Future of Education
Sound Installations: Exploring Physics and Sustainability through STEAM-Based Learning
Slavica Bernatović, Tehnička škola Slavonski Brod (Croatia)
Abstract
This educational project integrates physics, sustainability, and creative expression through student-designed sound installations in a STEAM-based learning environment. The main objective is to develop students’ understanding of fundamental sound concepts, including frequency, amplitude, resonance, and vibration, through hands-on, inquiry-based activities.
Students designed and constructed small harp-like musical instruments to explore how sound is produced and modified through different materials and structural designs. They used recycled or locally available materials, applied string art (ArtString) techniques, and also created harp frames using 3D printing technology, enabling a comparison between traditional craftsmanship and modern digital fabrication methods.
The project integrates science, technology, engineering, arts, and mathematics by investigating how material properties, tension, and structural design influence sound production and acoustic behavior. Through this process, students developed critical thinking, collaboration skills, creativity, and the ability to apply physics concepts in real-world contexts.
In addition, the project promotes inclusive participation in STEAM education and raises awareness of sustainable design practices aligned with the Sustainable Development Goals (SDG 4, 5, 9, and 12). The outcomes include improved understanding of sound physics, interdisciplinary competencies, and the creation of functional harp-based sound installations documented through visual and digital evidence within an eTwinning educational environment.
