Today, we went to the Museum of Natural History. I was very happy because my favorite subject is science, and I really like dinosaurs. When we passed the entrance, we saw a huge dinosaur fossil. Its name is Acrocanthosaurus. This type of dinosaur was easily frightened/was frightening (?), and ate meat. My teacher said that its most important feature was the long, saw-like thing that projected from its neck to its tailbone. After that, we went to see a short 3D movie that showed the birth of Earth. As you know, the 'universe' refers to all of space and all of the stars, planets, and other forms of matter and energy in it. The universe was born about 15 billion years ago during the Big Bang. However, Earth, the planet where we live right now, was formed about 4.6 billion years ago. The process of the birth of earth was really hard to memorize. Anyways, we learned about the solar system next. Outer space has numerous stars. There are 9 planets, starting with the planet next to the sun to Neptune. When a planet turns on its axis, it is called rotation. For me, my favorite planet is Jupiter. Jupiter is the planet which symbolizes the king of the gods, Zeus. When I see Jupiter, I can feel Zeus' power and dignity. We learned about horoscopes, too. After drinking water on the third floor, we went down to the second floor to see the mystery of sharks. I saw Megalodon's teeth, and they were as big as my friend Jagger's head. Finally, we went to see the exhibit about the history of living things. We learned about the Precambrian Era, the Paleozoic Era, the Mesozoic Era and the Cenozoic Era. Cyanobacteria produce oxygen through photosynthesis. Dinosaurs lived during the Mesozoin Era. They can be divided into two groups: herbivores and carnivores. Herbivorous dinosaurs ate vegetables, and they had flat teeth and horns to protect their bodies from enemies. Carnivorous dinosaurs ate meat, and they had sharp teeth and eyes in front to see well. Most people's favorite dinosaur is the T-Rex, but for me, mine is the Stegosaurus. It has a really long tail and a horn at the back of its tail to protect itself from dangerous dinosaurs. What's really special is that it has big horns on its back. The horns make it bigger than dangerous dinosaurs. I think it is really......... Cool!!!!!

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