Today, we went to Natural History of Museum. I was very happy because my favorite subject is science and I really like dinosaurs. When we pass the entrance we can see a hugh dinosaurs fossil. Its name is Acrocanthosaurus. They were easily frightening and ate meat. Teacher says that their most important feature is the long saw-like projecting that developed from their neck to their tailbone. After that, we went to see short 3D movie showing the birth of Earth. As you know, the universe means is the whole of space and all the stars, planets, and other forms of matter and energy in it. The universe was born about 15billion years ago while big bang. However, Earth, the planet where we live right now was formed about 4.6 billion years ago. The process of birth of earth was really hard to memorize. Anyway, we learned the solar system next. Outer space has numerous stars. There are 9 planets starting with the planet from sun to Neptune. When these planets turns on its axis, it is called rotation. For me, my favorite planet is jupiter. Jupiter is the planet which symbolize the king of god, Jeus. When I see jupiter, I can feel jeus power and dignity. And then we learn about Horoscope too. After drinking water on third floor, we go down to second floor to see mystery of sharks. I saw Megalodons teeth and it was as big as my friend Jaggers head. long-awaited, we went to see history of living things. There were Precambrian Era, Paleozoic Era, Mesozoic Era and Cenozoic Era. Cyanobacteria which produce oxygen through Photosynthesis. Dinosaurs lived in Mesozoin Era. They can divided to two. Herbivorous and carnivorous. Herbivorous eat vegetables so they have flat teeth and horn to protect their body from enemies. In fact, carnivorous eat meats so they have sharp teeth and eyes are in front to see well. Most of people's favorite is T-Rex but for me, it is stegosaurs. They have really long tail and horn at the back of tail to protect themselves from dangerous dinosaurs. Specially, they have big horns in back because it makes to be bigger than dangerous dinosaurs. I think they are really......... Cool!!!!!

Today was very interesting day for me and I think it really helps me. If I have chance to come here again I hope I can explain this museum to foreigners. Today was the best day of Mari story.~~ ^-^
