• Engage students in hands-on activities with the same procedures used in real police and FBI investigations.
• Target observation, critical thinking skills, and teamwork; incorporate math extensions.

In this bundle, students try to figure out “who done it!” They use a laser pointer and the “string method” to visualize bullet trajectories. Two suspects of different heights will be investigated as potential shooters. Students will catalog detailed observations at the crime scene, including investigations of rifling impressions on bullets and comparisons of cartridge cases. Students will practice cross-referencing spent bullets with information in published databases to identify the gun type and manufacturer.

Items in the bundle include a large-scale class size bullet model, the forensic bullet comparison set, the forensic cartridge casing comparison set, and the trajectory kit.
