The contextualization and experimentation, as well as use of case studies are educational resources that allow the learner to associate the content discussed in classroom of in significant way. That way a case study is structured involving Forensic Chemistry to be used for a practical activity. It was developed a fictional story which was simulated a fraud in signing a document. The ink pen used for the signature on the document was analyzed using Chromatography technique on Paper. Four blue pens of different brands were analyzed for that could be compared the result from the document signature analysis. In order to identify which pen was used in the signature on the document and its respective owner, thus uncovering who was responsible for signing rigged. The ink analysis was performed by Paper Chromatography, other practices involving Forensic Chemistry have also been suggested, such as digital analysis, DNA analysis and analysis of the content of alcohol in gasoline. Using these suggested practices can be developed several case studies. Experimentation, case study, Forensic Chemistry and contextualization used appropriately make learning very attractive, motivating students to absorb effectively content, ie, promoting meaningful learning.
