| This case study was developed to promote student-active learning by engaging small groups of second semester organic students with a CSI style experience. All the techniques used in the laboratory have been presented in previous experiments. The goal of this study is to have the students apply these techniques to a “real-life” scenario, looking for inconsistencies and inferring possibilities. The students are provided with a selection of samples from a “body” retrieved from a lake (lake water, lung water, clothing, bottles from the scene, GC-MS data from blood and fingerprints). The apparent cause of death is drowning, but it is left to the small groups to determine evidence of foul play. Students use extraction, spectroscopy (FT-IR), and classical qualitative techniques to establish relationships among the water samples and cloth samples. Fingerprints are resolved using ninhydrin. The spectra from the blood samples leads to a literature search. The groups are required to hand in a report which includes labeled spectra and an analysis of their findings. |
