blood spatter

FSB01blo o d spatte rProgram overviewSession 3 – The relationship betweenheight and bloodstain diameter• Activity 1: FSB06, FSB07, FSB08• Conduct an experiment to find out howdrop size and shape changes with height.Session 4 – Influence of surface texture• Activity 3: FSB06, FSB07, FSB08• Conduct an experiment to find out howthe type of surface changes the sizeand appearance of a bloodstains.• (Compare surfaces such as glass, lino,carpet, wood, concrete and grass.)Session 5 - Determining the directionof travel from a blood droplet patternActivity 4: FSB06, FSB07, FSB08• Conduct an experiment to find out how youcan determine the direction a blood dropletcame from. and therefore the angle of impact.Session 9 – Determining the area of origin• Activity 7: FSB06, FSB07, FSB08• Students receive a pattern of bloodstainsthat has been created by a different group ofstudents. Using skills and techniques developedthroughout the program they attempt todetermine the area of origin of the bloodstains.Session 10 – Scenario• Activity 8: FSB07, FSB09, FSB11• Given a scenario and using the knowledgethey have gained over the last few lessonsstudents try to reconstruct a crime sceneusing blood splatter (need to keep recordsof each experiment piece togetherSession 11 – What happened?• Sharing reconstructions and re-enactingwhat they think happened.• Students present their evidence.Session 6 – How does the angle ofimpact affect blood droplets?• Activity 2: FSB06, FSB07, FSB08• Conduct an experiment to find out how theangle of impact affects blood droplet patterns.Session 7 – Calculate the angle of impact• Activity 5: FSB06, FSB07, FSB08• Use the results from Activity 4 to calculate theangle of impact of various blood droplets.Session 8 – The effect ofvelocity on bloodstains• Activity 6: FSB06, FSB07, FSB08• Do a demonstration or conduct an experimentto assess the effect that changing the amountof force has on the resulting bloodstains.
