Abstract:

A wide range of teaching strategies have been employed to improve the effectiveness of STEM education. In some studies, music has been used as a tool to help memorizing scientific concepts (Crowther et al., 2016. Leveraging the power of music to improve science education. International Journal of Science Education 38: 73-95). However, music (without lyrics) can also be considered in itself as an interesting way to explore and explain the complexity of both natural and artificial structures, and to guide learners of every age towards the deep understanding of the difficult concept of molecular order. For this purpose, we developed a scientifically based “decryption” method to assign a given sound to single atoms within crystals. All sound parameters (pitch, duration, timbre, and dynamics) are based on physical and chemical properties of the atoms involved in the structure. The “crystal soundtrack” is accompanied by animations highlighting the position of each atom considered in its context. Possible applications of this novel educational approach range from chemistry (atomic structures, the periodic table, the octet rule), to Earth sciences (the structure of natural crystals), material sciences (artificial structures), and biology (macromolecules such as sugars and nucleic acids). Musical examples will be presented and discussed.
