Today, I went to Natural History Museum. At first, there was about Universe and Solar system. The Universe was formed by a BIG BANG. At solar system, there are Mercury, Venus,Earth, Mars,Jupiter, Saturn,Uranus, and Nepture. I want to visit Saturn because there is a ring around the saturn. The solar system is named by Greek myth. Next, we learned about volcano. In Korea Baekdu and Hala Mt. are dormant volcanoes. Third, we learned about living thing. Cyanobacteria produces oxygen by photosynthe and mesozoic area. Carnivore dinosaures ate meat. Herbivor dinosaures eat plant. My favorite dinosaures is T-rex because it was very scary. At cenozoic area there were Mammoth and firet humans. There war six types of livingthing. There are fish, amphibian, reptile, mammal, bird, and insect. I learned many thing about science. I want to visit again.
