Powder Room Lab

In this lab I learned and used the methods that forensic scientists use to identify foreign substances such as powders (drugs).  The substances we tested were: Brogaine, Speclate, Rotaran, Barrop, Lixonin, and Table Salt.  We tested these powders by observing with a hand lens, adding acetic acid, observing on a hot plate, adding water, adding sodium carbonate, and adding Lugol's solution.  Throughout these tests we noticed and recorded the results and differences of the powders.  This lab could be helpful in preparing us for the mission if we find unknown substances, powders especially on the mission.  This lab also helped to develop our skills of observation, which is helpful to any scientific thing.

Urinalysis

First of all, when do you find urine at a crime scene?

Anyway, me and my partner thought it was pretty obvious from the beginning which pee sample matched the sample from the cellar.  You could tell from just looking at it.  Then the absolute gravities were way different.  Then one pH was way different from the other two.  And one was cloud after heating and the other two weren't.  So, this would be very useful evidence since it clearly shows differences between samples and there are so many different tests for differences.  This will be helpful for the mission if we come across mysterious pee on the mission.
