We describe an investigative based laboratory that is compatible with the organic chemistry I laboratory. The principles and concepts of chromatography, melting point, solid / liquid extraction, and liquid / liquid extraction techniques are targeted. This laboratory has been developed to replace the traditional extraction laboratory of an acid/base/neutral organic mixture. The targeted organic concepts and techniques are investigated in the context of a possible crime investigation. Students are required to extract, characterize, and identify a sample found at a possible crime scene.
