Students will learn how to document bloodstains using roadmapping equipment materials

Video based Learning Object showing passenger vehicle and light duty truck Event Data Recorders (Airbag Control modules and Powertrain COntrol Modules).

This learning object describes the equipment and supplies needed to document bloodstain patterns.

Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.
