A Burning Question™ Fire Debris Analysis

When investigators discover three deceased victims at a burned vehicle crash site over the side of Backbone Mountain, they question whether the burned vehicle was merely the result of the crash, or could have potentially been the result of foul play.

Description

With this kit, students must determine the circumstances under which the vehicle at a fatal crash scene caught fire.

Learning Objectives

  1. Learn how forensic scientists analyze fire debris for the presence of ignitable liquid residue in suspected arson cases.
  2. Test fire debris for the presence of specific ignitable liquids by first analyzing known reference samples.

In this lab students will examine fire debris from the interior of a burned vehicle at the site of an automobile crash. They will learn how forensic scientists analyze fire debris for the presence of ignitable liquid residue in suspected arson cases. In addition, students will learn to presumptively test fire debris for the presence of specific ignitable liquids by first analyzing known reference samples. Students will then apply what they have learned in the analysis of fire debris collected from the crime scene in attempt to determine if the fire was started under suspicious circumstances.

As in all Lyle and Louise modules, this kit is geared to high school and undergraduate courses, and is matched to National Science Education Standards. This kit is designed for 6 labs groups (up to 30 students).

Next Generation Science Standards

  • MS-PS1-4. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
  • MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved
