My favorite activity during the week was the liquid nitrogen activity. During this week we have done and learned lots of things. We've launched rockets. We interviewed a technician and an astrophysicist. Dr. Joe Davila was the instructor who showed us some very interesting things about liquid nitrogen.
Liquid nitrogen can freeze things.
My week at NASA I learn that I am a very good interviewer. The people at NASA are very nice. The class interviewed many people. Two people at NASA came in and showed us if you put anything in liquid nitrogen it will freeze. We, the class, interviewed Dr. Steve Odenwald, Vanessa Harvey, Ms. Charlene Malloy, Dr. Carol Jo Crannell, David Carter, Dr. Joe Davila, Nelson Reginald, and Granville Priest.
