Materials science is an essential cornerstone of multiple disciplines in the field of engineering. However, new engineering students often lack engagement and interest in learning materials science. To this end, we have developed the Multi-Material Marbles Game, an educational tool designed to introduce students to material properties and materials selection through tactile interaction and hands-on experimentation.
In the game, students measure key material properties - such as mechanical loss coefficient, thermal conductivity, electrical resistivity, and mass density - using spherical marbles made from different families of materials. They then apply these measurements to construct a Material Property Chart (Ashby plot). The tactile hands-on experience of the material marbles helps foster an understanding of how different materials behave. The game also illustrates the thought process behind materials selection, a critical aspect of engineering design. By engaging learners in this physically interactive experience, the game aligns with the principles of experiential learning, where knowledge is acquired through active participation rather than passive observation. This gamified approach not only makes materials science more accessible but also bridges the gap between theoretical concepts and practical applications in engineering design. The game incorporates a variety of Universal Design for Learning (UDL) principles that have been shown to improve learning outcomes for all people.
The Materials Marbles Game is adaptable for both classroom use and outreach initiatives, making it an effective tool for high school seniors, first-year engineering students, and public engagement events. Results from pilot studies show high levels of student engagement and an increased interest in exploring materials science further. All elements of the game (e.g., CAD design, game instructions, material information cards, materials/equipment list) are open source, allowing educators and outreach event organizers to download the information and implement the game in their classrooms.
