Coming here to NASA was a very good learning experience.While I was here at NASA for the week I learned many things.One thing I learned was that scientist use a method to determine what type of meteorite that they find.I also learned what a comet is made out of which is really just a ball of dry ice.Here at NASA we made a comet out of dry ice,water,ammonia.and other kinds of ingredients.The dry ice is not water but frozen carbon dioxide.Frozen carbon dioxide goes through a process called sublimation which is that the carbon dioxide doesn't go into the liquid stage like when water freezes.We also interviewed many people who works here.Many people we met has very important jobs.I many new vocabulary words I never knewbefore I came here to NASA.Coming here to NASA was a great learning experience and hope to come another time.
This week at Goddard Space Flight Center I learned and experienced many things. The first day we arrived at Goddard Space Flight Center, for SUNBEAMS , we met Ms. Stokes and Dr. Jo SUNBEAMS' creater. We were given a tour of Goddard Space Flight Center. We saw where scientist and enginers build and test satellites. As well we learned binary code.
The second day we went to the Rec. Center at Goddard. We met two scientists Dr. Evans and Mrs. Solomon. They taked about asteroids and the Near Earth Asteroids Rendezvous mission NEAR. We made play-doh meteorites , using beeds to reprosent different atoms.
On day three Ms.Stokes made a comet ,not real, out of dry ice (frozen carbon- dioxide) , dirt, rocks, water, sand, ammonia, and molasses. It was cool. Pun intended. After that we dissected that we had made the day before. We cut them in halves and counted the beeds inside. It was simulatoin of what scientists do to real meteorites to find-out were they come from. We also looked at gas tubes using a difracting grating (it separated light from the tubes to show the emission lines. Then we took a group picture.
Today, day four we are doing this.
