An experiment seated in an industrial context can provide an engaging framework and unique learning opportunity for an upper-division physical chemistry laboratory. An experiment that teaches NMR/MRI through a problem-based quality control of citrus products was developed. In this experiment, using a problem-based learning (PBL) approach, students construct knowledge about the physical properties that make NMR and MRI possible, apply them to make decisions about experimental conditions, and write a final report in the form of a technical report for a fictional company. Implementation in a laboratory course demonstrated that the majority of students met the desired learning outcomes.
