Hello everyone, my name is Yu-Jin.Today I went to museum of natural history.First we saw a movie containing story about how earth was born. Earth was born by small gases and dust attached to each other and other and it exploded to make the earth's shape, this phenomena is called "Big bang". When many planets were made up, the arrangement was called "Solar System".The earth is 4.6 billion years now. All the planets will be similar age with earth.
Cyanobacteria made the earth fill with oxygen. Dinosaurs can be divided in to two parts. Herbivorous and Carnivores. Herbivores ate plants but Carnivores ate meats. To protect themselves from Carnivores, herbivores developed their protections. Also, in Korea, there were a lot of footprints of dinosaurs.
Elephant's trunk is made out of numerous muscles.they breathe with their trunk. The trunk helps eating, pulling out grass, and to water their body.
When I learned these, I felt I didn't study well about the history in the past. So, I will study more about the past.
