Kemtec™ Analysis of Minerals & Soils Classroom Kit

Minerals and Soils Analysis teaches students to utilize physical and chemical techniques to thoroughly investigate crime scene samples. Soil, glass, dust and metal traces are just some types of materials which are analyzed in this kit to link a suspect to the scene of the crime.  Analyses include comparison of acidity; comparison of particle sizes using sieves; comparison of particle densities using density gradient tubes; and comparison of minerals present through the use of wet chemistry. Required, but not included: fume hood, UV light, balance, microscope, oven/lamp/or hot plate, glassware, and general lab supplies. Contains lead nitrate. Designed for 24 students working in six groups of four. Meets national standards for grades 9-12.
