Yesterday, I went to the Museum of Natural History. I saw very many things in there. There was a movie about 'The Earth's Birth', dinosaur's bone, and there was my favorite, 'Universe'.    I could see 9planets like Sun, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. But the explane under the pluto's pictuer said,  'pluto is too small to call planet in solar system. I thought   'Oh, I think astronomer doing many things about universe.'   When I come there one more time, I will saw exhibits more carefully and know more about them. I was very good experience.
