United Scientific™ Ink Chromatography And Forensics Stem Kit

Unique Stem Teching Tool For Introducing Your Students To The Fascinating Chemistry And Physics Behind Invisible Inks, I.E. Colorless Substances Usable For Writing That Can Be Made To Run Color Using A Chemical Or Physical Process.
Use this kit to introduce your students to ink chromatography and its application in solving forensics cases. Students gain experience in creating ink databases, identifying ink tags to date various inks and then use them (as professional document examiners do) in solving two mysteries involving document inks - an apparent suicide note and a forgery case. Includes materials for three detailed activities (with model and inquiry investigational paths - a total of four investigational activities), which can accommodate up to 40 students. Also contains a DVD with PDF Teacher and Student Guides and other digital content.

Covered concepts include: data analysis, chromatographs, inks and their composition, mixtures, compounds, molecules, solubility, affinity, polar substances, Rf values, capillary action, light energy, fluorescence, and hypothesis testing.
