Your students must determine if these receipts are legitimate business documents or evidence of a crime. To do this, students must determine objective criteria for hand writing analysis, and then apply these criteria when examining suspect receipts. After analyzing the handwriting, students will dissolve the ink from numbers on the suspect invoices. Then, using thin layer chromatography, they will create an ink profile for each of the samples taken from the reciept. From this information, students will determine if the same ink was used to fill out the entire form. Finally, by combining where different inks were used with what reciepts are suspected of forgery, students can develop a complete theory of the suspected forgery. As in all Lyle and Louise modules, this kit is geared to high school and undergraduate courses, and is matched to National Science Education Standards.
