Activity 6.1 Seeing red blood spatters
2. Deduce how the materials of the surface influence the shapes and boundaries of the blood spatters?
A non-porous smooth surface gives a blood spatter with smooth and regular boundary.
A porous rough surface gives a blood spatter with jagged and irregular boundary.
All of the blood spatters are nearly round-shaped. The materials of contact surface do not have a direct influence on the shape of the blood spatter.

Activity 6.1 Seeing red blood spatters
Conclusion:
Write a few sentences to conclude your findings in this experiment.
Free-falling blood drops tend to form circular blood spatters. The materials of contact surfaces do not influence the shape of the blood spatters.
A non-porous smooth surface gives a blood spatter with smooth and regular boundary.
A porous rough surface gives a blood spatter with jagged and irregular boundary.

Notes: Scallop pattern - bloodstain produced by a single blood droplet characterised by a wave-like, scalloped edge.
Satellite spatters - small droplets of blood projected around a drop of blood upon impact with a surface.
Spines – pointed edge characteristics that radiate away from the centre of a bloodstain; dependent on impact velocity and surface texture.

Activity 6.4 Case Reconstruction 1. Finding the Point of Origin
Part II. Stringing method-Step 10
Conclusion:The point of origin of a blood spatterhad been found by using stringing technique.The directionality and angle of impact of each blood spatter were determined. Then a string was suspended from each spatter according to the calculated information.The position where most strings were crossing each other indicated the position of the origin. In this experiment, two origins were found. The first origin was the primary source of impact. The second origin would be caused by swinging of hammer in air.
