The Chocolate Curriculum: A Gateway to Materials Science and Engineering and Python Programming

Most incoming college students have
little awareness
of materials
science and engineering (MSE) as a discipline, resulting in barriers
to entry for a field central to modern technology. To address this
gap, we designed a short course curriculum that introduced high school
students to MSE concepts through accessible, hands-on, and computationally
driven activities framed in the context of chocolate science. The
curriculum, rooted in the Context-Based Learning framework, aimed
to build scientific literacy and present an engineering perspective
by linking everyday observations to the underlying materials science
tetrahedron of “structure, process, properties, and performance”
relationships. Students engaged in low-cost activities that explicitly
connected to advanced laboratory techniques, such as differential
scanning calorimetry and polarized optical microscopy, introducing
them to tools that produce research-quality data but rely on the same
principles. Computational modules introducing Python for modeling,
quantitative analysis, and data visualization showed how computational
skills can aid broader research efforts and enabled students to produce
publication-quality figures and investigate hypotheses. This integrated
experimental–computational approach with the chocolate theme
lowered barriers to MSE, increased awareness of the field, and empowered
students to become citizen scientists.
