Lesson 1: Analyzing Evidence

Key Idea.

Section 1

Property Analysis

Key Idea

Forensic science relies on matching properties. A mysterious acid was used to dissolve glass during a robbery. Since very few substances can dissolve glass, this unique corrosive property identifies the substance as Hydrofluoric Acid.

Identifying the chemical weapon is the first step in narrowing down the list of potential suspects.

Section 2

The Supply List Evidence

Key Idea

Investigators examine the chemical supply lists of the suspects. This document serves as evidence. Scientists analyze these lists to see who had access to the raw materials needed to make the acid.

However, merely possessing chemicals isn't enough; the suspect must have the right chemicals to create a specific reaction that yields the dangerous acid.
