Our Shot in the Dark Bullet Striations Forensics Kit challenges students to analyze how striations, or striae, are created upon bullets when they are fired. Students will examine fired bullets and perform a web quest to learn about various features of bullets in Lab 1. They will measure detailed photos of evidence bullets, gather data, and form a hypothesis about the origin of the bullet. Lastly, they will conduct a mock trial to hold a suspect accountable for his or her actions.

Bullet Striations challenges students to think critically and to solve a crime using gathered evidence and analysis. Students will evaluate striations on provided bullets, in a web quest, and using pictures. They will collect data and calculations for comparisons on:

  1. Diameter
  2. Length
  3. Weight
  4. Number of Grooves
  5. Number of Lands
  6. Width of Lands
  7. Rifling Twist
  8. Color Variations

Students will also draw a detailed model of the crime scene bullet, answer thought-provoking questions, and prepare for a trial!

This kit provides students with a hands-on, collaborative learning experience using methods currently used by professionals in the forensics field.  Link to kit below!
