The Museum of Natural History

           Today, I went to the Museum of Natural History. I thought it was kind of fun but also scary because of the fake-dinosaur bones. But, it was also extremely fun because I got to know a lot about the universe and dinosaurs. First, I thought this was interesting, but do you know what Pangaea was? Pangaea was  when all of the continents, such as Earth, Uranus, and Neptune, Australia, the Americas, Asia, Africa, Antarctica and Europe were connected together as one land. Also, in the space, there are 9planets  8 planets in total, (starting closest from the sun,) 1.Sun (the sun isn't a planet :) 2.Mercury 3.Venus 4.Earth 5.Mars 6.Jupiter 7.Saturn 8.Uranus 9.Neptune, but Pluto, a planet which rotated from the Sun, suddenly did not rotate around the Sun, so it was not one of a Solar System anymore. Pluto is too small to be considered a planet-it still rotates around the sun as do many other "dwarf" planets.

           In our history from Earth was born, we had 4 eras until now, in the Precambrian Era, bacteria and cells lived, and one of the living cells were the Cyanobacteria which produced oxygen through photosynthesis. In the Paleozoic Era, only reptiles lived, and in the Mesozoic Era, dinosaurs lived eating lots and lots of interesting things. Also, the Cenozoic Era, which also means today, has lots of animals living, such as human and other mammals.  Good work, your sentences are almost all perfect but some of your information is wrong-did your teacher tell you this or did you just make a mistake?
