Full Description

Now an updated and enhanced New GEMS edition. Challenged to determine which of several black pens was used to write a ransom note, students learn and use paper chromatography, as they explore the concepts of solubility, pigments, and separation of mixtures. New sessions provide students with multiple opportunities to visualize the molecular nature of matter as they create and revise their own models and consider the limitations of models.

For more forensic activities also see Fingerprinting and Mystery Festival.
