The Museum of Natural history

  Today, I went to museum of natural history. At there I learn about the Earth's Birth, living things of period, solar system, and dinosaurs. I will say to you this 5 things. First, it's about Earth's Birth. 46 billion years ago at Earth, there were no living things because Earth was very hot. 40billion years ago, Magma changed to crust and then 38 billion years ago, the ocean was on the Earth, so the Cyanobacteria is lived at Earth on Precambrian Eara. Cyanobacteria breathed with oxygen. On Paleozoic Era, there were some plants and insects. Mesozoic eara, dinosaurs were lived. Dinosaurs, there were two types of dinosaurs. One is carnivore and one is herbivorous. Herbivorous ate plants and carnivore ate herbivorous. Last it's solar system.

Solar means "sun". At solar system there are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. There are also have Pluto, but Pluto is too small and it goes out to solar system on 2007. There are 4 small planets and 4 big planets. I like Venus because it's beautiful planet.
