Analysis of Minerals & Soils 10-500
Target Grades: 9-14
Minerals and Soils Analysis teaches students to utilize physical and chemical techniques to thoroughly investigate crime scene samples. Soil, glass, dust, and specks of metal are just some of the trace evidence 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. Now includes Hands-On Soil Classification Activities for Determining Soil Texture by Sedimentation or by Using the Feel Method. Required not included: fume hood, UV light, balance, microscope, oven / lamp / or hot plate, glassware, and general lab supplies. Contains lead nitrate. Meets national standards for grades 9-12.
