While collecting evidence at a crime scene, investigators may recover substances they can't identify in the field. With the Forensic Chemistry of Unknown Substances Kit, students carry out mock crime lab testing.
Along with evidence such as fingerprints, hair, and fibers, crime scenes may display traces of unknown chemicals or powders. This type of evidence heads to the crime lab for identification.
With this kit, use observation skills, senses, and chemical tests on a series of known substances and two unknown substances. Then try to identify the mystery substances based on observations and recorded data.
From Innovating Science, the Forensic Chemistry of Unknown Substances Kit has enough material for 5 groups. Teacher’s Manual and Student Study Guide copymasters are included.
You provide lab scoop or spatula.
WARNING: This product can expose you to Respirable crystalline silica, which is known to the State of California to cause cancer.
