In this experiment, students will use observation skills, senses, and chemical tests on a series of known substances as well as two unknown substances and then attempt to identify the mystery substances based on observations and recorded data.

Often times, when collecting evidence at a crime scene, investigators may recover substances they are unable to identify in the field. Along with evidence such as fingerprints, hair, fibers, etc., there may be traces of unknown chemicals or powders left behind by the perpetrator or perpetrators. Evidence of this nature is sent to the crime lab for identification.
