Lesson 5 and 6

Lesson 5 was a briefing on the CSI PT (group), along with a video (edited from a Japanese movie) showing a CSI case. I missed quite a bit of this lesson, only managing to catch the end of the video, due to a lengthy MSP phototaking. :(

In lesson 6, we were introduced to the idea of blood spatters! Using the shape and size of blood spatters, we can actually know more about the crime committed, for example, what kind of weapon was used and how the victim might have been injured/murdered. Another video was shown to better illustrate the workings of analysing blood splatters, and how it can be quite misleading at times.

A lesson learnt from this video is: do not jump to conclusions! Make unbiased observations first before inferrences. Keep an open mind at all times. I think this is really important for scientists and in this case, the CSI people, because the answers to a case might not be as expected.

Next up in lesson 7 would be hands-on experiments on blood splatters, investigating how the distance between the blood drop and the surface, as well as the latter's angle of elevation, affects the shape and size of blood splatters.
