EDUCATIONAL APPLICATIONS OF METALLURGY IN LABORATORY SETTINGS FOR EARLY CHEMISTRY, PHYSICS AND GEOSCIENCES CLASSROOMS
Elemental metals with low melting points such as bismuth, zinc and tin are melted down, mixed at various percent compositions, and allowed to solidify. The solidified composites are then broken open to examine the resulting internal structures. Changes in the physical properties of the new compositions are observed, with special attention paid to those with obvious changes.
The experimental results are the basis for a multi-tiered laboratory assignment for high school and early college chemistry and geoscience courses, whether it be in the form of an instructor demonstration or student performed laboratory exercise. These lab assignments will provide both a deeper appreciation of interdisciplinary science and an overall increased interest in STEM fields. From introductory, inquiry-based techniques in chemistry to more advanced concepts in petrology, each lab can be tuned to cover a wide spectrum of educational applications.
