This article explores the integration of physics knowledge and science, technology, engineering, arts, and mathematics (STEAM) education in high schools through a unique project that connects traditional Vietnamese culture with the production of moon-shaped lutes. The moon-shaped lute, known as “Đàn Nguyệt” in Vietnamese, holds great cultural significance in Vietnam. By incorporating physics principles into the lute production process, students develop a deeper understanding of its construction, sound production, and structural stability. They explore concepts like material selection, sound propagation, and ergonomic design to enhance the instrument’s craftsmanship and playability. This interdisciplinary approach not only fosters scientific and technical skills but also preserves and promotes traditional Vietnamese culture. Engaging students in projects that combine art, science, and culture highlights the power of STEAM education in nurturing well-rounded individuals who have a strong connection to their heritage. The integration of physics knowledge and cultural elements in this project demonstrates the value of interdisciplinary learning and its impact on students’ appreciation for their cultural identity.
