On Oct 26 my class went to the Natural history museum. We looked at different planet when we
traveled around. We watched the big bang, and we watch another move with Whoopi Golgberg.
first we went to the Hall of metorite that landed in greenland. Also that Ahnighto is so massive that iron posts go at the bottom of the museum.
Then we went to see a movie called the big bang and the universe was hotter. then we went to
see jounry to the stars with whoopie goldberg. it was about how stars created the sun and it
gave facts about the sun.
The Q's i have was how many stars did it take to make the sun. also can people land on stars.
