Today was the third day of camp.
Today’s class was titled DNA Testing. So as you can guess we were
testing DNA. There are many different types of DNA, but we decided to
use the most obvious one! Blood. We used horse blood (donated by our
teacher Dr. Park) for obvious precautions.
What we did with the blood was we wanted to get the
only part that actually contains DNA which is the white cell. We learned
the different types of cells in our bodies, and learned how to tell what
you blood type is. Then we learned the definition of DNA: deoxyribose
(sugar), nitrogenous (a base), and phosphate. We also learned the
responsibilities of the cells in our body.
After experimenting with the blood, we began to learn
how to make a mold our of seaweed gelatin. The mold is used for DNA
testing. When we finished making the mold, we put it inside of our
homemade trays, and then filled it up with the DNA. Our group believes
that the funnest part of the day was when we were experimenting with the
blood. All of us got to see and feel a bloody clot, which we later
learned that the cells in your body create blood clots when there is a
open wound and the blood absorbs the air.
In conclusion, our days at Metro have been
interesting, exciting, and fun filled. This is a unforgettable
experience, I’m very grateful for the opportunity.

Today we learned a little bit
more about forensic anthropology. Professor McCormick gave us a very
thorough lecture about forensics and digging up dead people. She showed
us a lot of interesting pictures when she was out in the field digging
up dead bodies. We also learned a lot about bodies and their decaying
time. I think that everyone learned a lot about dead people and the
types of death.
After we were done with the
lecture, Professor Pinto then broke us up into groups and we went to
different station and did stuff with bones. We got to sex, age, and
ancestor bones from dead people.
A lot of the students were
getting tired during class, so some people feel asleep and dozed off in
outer space.
