Module 6 Lesson 3 Student Notes DocumentForensic Science, NCVPSComplete the following prompts as you move through the notespresentation.You will submit these notes to your teacher in the course.Introduction:In your own words describe what this lesson is about.This lesson is about analyzing bloodstains to reconstruct a crime scene at a 90%accuracy rateStandards… What are the standards that you will cover in this module?1.00- Understand and apply appropriate forensic science techniques for crime sceneinvestigation, focusing on the recognition, documentation, collection, andpreservation of evidence.1.00 - C Determine and use appropriate techniques to search crime scenes.1.00 - D Find, collect, and document evidence2.00 - Use scientific knowledge and standard scientific techniques to analyzeforensic evidenceKey Terms… For each of the key terms, roll over the term to see the definition.Write the term that matches each definition below: (Terms are not in the same orderas the key terms in the lesson.)Patent dropA drop of blood from which a wave, cast-off, or satellite spatter originated from.SpatterThat blood which has been dispersed as a result of force applied to a source of blood. Patterns producedare often characteristic of the nature of the forces which created themAngle of impactThe acute angle formed between the direction of a blood drop and the plane of the surface it strikes.Projected bloodspatterA bloodstain pattern that is produced by blood released under pressure as opposed to an impact, such asarterial spurting.Origin/sourceThe common point (area) in a three dimensional space to which the trajectories of several blood drops canbe retraced.Passive bloodstainsEvidence that liquid blood has come into contact with a surface.Bloodstain drop(s) created or formed by the force of gravity acting on an injured body.Blood spinesThe pointed or elongated stains which radiate away from the central area of a bloodstainContact/transferblood stainsA bloodstain pattern created when a wet, bloody surface comes in contact with a second surface. Arecognizable image of all or portion of the original surface may be observed in the pattern. Results fromobjects coming in contact with existing bloodstains and leaving wipes, swipes, or pattern transfers behindsuch as a bloody shoe print or a smear from a body being dragged.
