ABO blood typing test.
Swati and Sara pipetting out white cells.
Before we began
our lesson of the day we wrote on the white board about what we learned
about yesterday, today we talked about DNA and blood. We were given an
introduction to DNA. Then we were taught how to separate the white
blood cells in horse blood. During lunch we watched an episode of
CSI and then wrote reflections about the episode.

We then cleaned
off our footprints from the previous day. After that we were taught how
to make the gel for Agarose Submarine Gel Electrophoresis. This is a
method to examine someone’s DNA and even compare it to another person’s
DNA, which is very helpful in the forensics field. We then examined an
example of an Agarose Submarine Gel Electrophoresis that Dr. Park
brought. She then taught us how to use a micropipette to load the DNA
in the wells. We used the example gel to solve a crime. Then we started
watching the movie GATTACA, which talks a lot about genetics, and has
very good science in it.
