Forensic Palynology as Classroom Inquiry

This activity introduces the science of forensic palynology: the use of microscopic pollen and spores (also called palynomorphs) to solve criminal cases. Plants produce large amounts of pollen or spores during reproductive cycles. Because of their chemical resistance, small size, and morphology, pollen and spores can be used to link individuals or objects to specific locations where the parent plants grow. Students will use a digital pollen database and Google Earth to link pollen trace evidence to a specific crime scene. The methods presented are based on those used in criminal cases and palynological techniques used by forensic scientists. Step-by-step instructions for a hands-on investigation and a case simulation are presented.
