May Forensic Science Lesson Plans Date 5/3, 5/4 Tues/Wed Objectives Analyze bloodstains to determine sequence of events at a crime scene. Discuss methods used to search for traces of blood. Activities 5/5, 5/6 Thurs/Fri 5/9, 5/10 Mon/Tues Establish the relationship between dropping height and blood drop diameter. Recognize patterns around the drop, such as satellite spatter or spines. Develop an understanding of the common types of bloodstain patterns found at a crime scene. Create and examine vertical blood drop patterns on various textured surfaces.
