When investigators discovered three deceased victims at a vehicle
crash site over the side of Backbone Mountain they retraced the
vehicle’s path and also discovered several pieces of broken glass lying
in the roadway.
In this lab students will examine the refractive
index of various glass fragments. They will learn the importance of
glass analysis in the forensic field and how this analysis is performed
by forensic scientists. In addition, students will learn to
microscopically determine the refractive indices of several known types
of glass, and then apply what they have learned in the comparison of
glass fragments collected from a crime scene to a potential source.
As in all Lyle and Louise modules, this kit is geared to high school
and undergraduate courses, and is matched to National Science Education
