During my third day at goddard girls summer program, we went to the umass stem labratory and I had lots of fun. In the morning, I did an experiment on body fluids and leg circumference. I learned that on Earth your body fluid is below heart level, but on the moon the water or H2o in your body is the same in all parts of the body. It is because of this that astronauts do not feel thirsty. In the afternoon, I really enjoyed designing, building, and demonstrating my cev. I learned that CEV is an acronym that stands for crew explorartion vehicle. The most fun part of today was talking with Mrs. Abby about DNA which stands for Deoxyribo Nucleus Acid. I learned from her that there is a nucleus in your brain cell and that one eighth of that is DNA. ALso, I gained knowledge on four types of DNA and tthat the combination of them makes each person unique and different. Today, was my favorite day so far.
