Today, I went to the Natural Museum of History. At first, I learnt about the Universe and the Solar system. The Universe was formed by a Big Bang. The solar system has 8 planets, they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. I want to visit Saturn because there is a ring around it. The solar system is named by Greek mythology. Next, we learned about volcanos. In Korea Baekdu and Halla mountains are dormant volcanoes. Third, we learned about living things. Cyanobacteria produces oxygen by photosynthesis it was from the Mesozoic era. Carnivorous dinosaurs ate meat. Herbivorous dinosaurs ate plants. My favorite dinosaur is the T-rex because it was very scary. In the Cenozoic era there were mammoths and the first humans. There are six basic types of living things animals; fish, amphibians, reptiles, mammals, birds, and insects. I learned many thing about science. I want to visit again.

Great work, excellent writing -just so you know there are many, many types of living things, and there are many more types of animals like arachnids(spiders) crustaceans(like crabs) etc...
