Identification of Unknown Substances I—
Forensic Laboratory Kit
By: The Flinn Staff
The FBI Crime Laboratory works closely with pharmaceutical compa- nies to produce tests for drugs they develop. The “standards” are critical for the proper identification of “unknown” drugs at a later time. Accurate drug identification has many crime scene implications. In this activity, students will assume the role of a crime lab chemist and create a set of standards for the identification of four simulated drugs. Once the set of standards has been established, students will perform chemical tests on an “unknown” simulated drug found at a crime scene. This laboratory, set in a crime scene scenario, will create enormous interest and motivate students to learn numerous chemistry procedures. All simulated drugs and chemical test materials are provided as well as detailed instructor and student materials.
Complete for 30 students working in pairs.
Identification of Unknown Substances II—
Forensic Laboratory Kit
By: The Flinn Staff
Drug-related crimes are extremely common. Just like crime scene investigators, your students will use thin-layer chromatography to sepa- rate and identify unknown drugs. Over-the-counter drugs to be tested are aspirin, acetaminophen, caffeine and a mystery substance. Students will enjoy using thin-layer chromatography and will marvel at the precision that can be achieved with this chemical separation technique. Kit includes TLC plates, development jars, microcapillary tubes, test solutions, and developing chemicals.
Complete for 30 students working in pairs. A short-wave UV light source is required and available separately.
Forensics—Entomology
Of Maggots and Murder—Forensic
Entomology Laboratory Kit

Washington State University, Pullman WA
Delve deeper into the world of forensic science with this student-capti- vating activity. Students will investigate a possible homicide using unusual clues that may break the case—maggots! Determining the living conditions and growth habitats of maggots helps forensic scien- tists calculate an approximate time of death. Was it murder? Students learn how to collect evidence and relevant data and use the informa- tion to solve the case. Simulated maggots will be used to determine the time and cause of death for four different simulated crime scenes. Materials may be saved and reused for future use. A must have forensic science activity!
Complete for 30 students working pairs.
