Often times, during a criminal investigation, police and crime scene investigators must use all available tools and pieces of evidence to work backwards and create the most likely scenario as to what might have occurred. Different types of evidence provide different pieces to the puzzle. Learn about the different chemical and physical characteristics and properties of glass. Find how forensic scientists use these differences to help provide evidence to solve crimes. This activity includes a teacher's manual, student guide, and analysis copy-masters. Includes one bottle of borosilicate glass beads, one bottle of flint glass beads, one bottle of soda-lime glass beads, one set of refractive index solutions, and 15 magnifiers. Materials needed: balance, 10 mL graduated cylinders, and test tubes. Enough material for 15 groups.
