Analyzing documents is an important aspect of forensic science. When a document, such as a will or a check, is used in a crime, it is important to determine its authenticity. Was the document altered? Was it forged? Careful analysis of documents might reveal obvious erasures, abnormal signatures, changes in handwriting or use of different inks, pencils or papers. Your students will experience five investigative techniques as they collect evidence and establish standards for analyzing crime scene documents. They will have fun as they try to copy signatures, conduct microscopic examinations of different papers and pencil markings and perform chromatography tests on various ink samples. Their analyses will establish the level of authenticity of crime scene documents. Pencils, pens, paper samples, chromatography paper and necessary chemicals are provided as well as detailed student and teacher materials.
