Yesterday was “Bloody Friday,” and goodness did we have fun with it.
We started off with a fake blood competition–students used this recipe (and added their own modifications) to make blood that looks the most real.
Then we looked at blood spatter patterns using this lab here in which we check out how the height the blood was dropped from, the surface that it’s dropped onto, the angle it’s dropped at, and the speed at which it was dropped affects how it looks. They got SO into it–I mean, who doesn’t love a mystery with a bit of blood in it?
We then ended the day with a Nobel Prize Winning Blood Typing Game and a Skype call with a Blood Analyst from the Medical Examiner’s Office in NYC.
