No Dumping

Figure from experiment 8 from Forensics with Vernier

Introduction

Early Saturday morning, two local teenagers called police after observing a large, dark blue pickup truck dumping toxic materials in City Park. Due to the dim morning light, the boys were unable to see a license plate number. They did, however, recognize the make and model of the pickup truck. Police quickly apprehended four suspects who drive trucks of this make and model.

Although tire tracks were found at the scene, the tread patterns were smudged. No toxic residue was found in the payloads of any of the trucks, but police were able to collect soil samples from underneath the bumpers.

Objectives

  • Identify characteristics of different soils to demonstrate that a suspect has been at a scene.
  • Use characteristic properties to identify a sample.
  • Measure the pH of soils.
  • Measure the water absorbency of soils.
  • Measure the conductivity of soils.
