Description
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. Kits contain structured, guided, and open investigations, at introductory, intermediate, and advanced levels, to make inquiry-based learning affordable and fun.
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 digital content, including teacher and student guides.
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.
