Students lift fingerprints from slides, develop prints on paper using both the Ninhydrin method and the Lugol Iodine method, use the cyanoacrylate fuming method to visualize a fingerprint on a metal spoon, and learn to identify direct prints. Each investigative group prepares “fingerprint evidence" for another class group to analyze and with the aid of Modus Operandi sheets, the group identifies the fingerprints of the suspects with the aid of fingerprint standards developed by the FBI. Includes instructional manuals and student worksheets. Required, but not included: fume hood, (6) one-quart jars or one-liter beakers. Meets national standards for grade levels 10-12.
