Product Description

Grades 7-12.
During the investigation, police have turned their suspicion on a suspect who has questionable receipts on his desk. Your students must conclude whether these receipts are legitimate business documents or evidence in a crime. Students will engage in a thorough handwriting analysis using thin-layer ink chromatography to create an ink profile for the suspected forged documents. Includes a fully illustrated teacher’s manual, 12 TLC plates, six development chambers, six bottles of solvent with droppers, six protractors, 100 microcaps, and suspicious receipts with copies.
