Ink Chromatography and Forensics STEM Kit

Correlated to the Next Generation Science Standards 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 (see below). Covered concepts include: data analysis, chromatographs, inks and their composition-mixtures, compounds, mixtures, molecules, solubility, affinity, polar substances, Rf values, capillary action, light energy, fluorescence, and hypothesis testing. United's series of STEM based curriculum kits accent the scientific method and independent inquiry featuring hands-on learning materials and exciting interactive digital content that can be accessed on a computer, tablet or your mobile device. Kits contain structured, guided, and open investigations, at introductory, intermediate, and advanced levels, to make inquiry based learning affordable and fun. Requires additional household materials for independent investigations. For pennies per experiment, your students have access to digital PDF content such as: Independent Investigation Inquiry suggestions Background information including content tables and concept animations Powerpoint concept presentation (and video version) Comprehensive Glossary Student activity PDFs have a special Typewriter functionality allowing them to take notes, record experimental data, and answer analysis questions. They simply e-mail their worksheets back to you!
