The school library’s computers have been stolen. Left behind was a ransom note demanding money. Help solve the crime using Thin-Layer Chromatography to separate the ink on the ransom note and ink found in markers tied to possible suspects. It may be possible to provide evidence as to whether or not the ransom note could have been written with a particular marker. This activity includes a teacher manual, student guide, analysis copy-masters, three different brands of felt tip markers, fifteen 30 ml chromatography solvents, 15 silica gel chromatography sheets, and capillary tubes. Materials needed: 15 chromatography chambers (500 ml beakers), 15 test tubes, and aluminum foil. Enough materials for 15 groups.
