Today, I went to the museum of natural history. I learned about the solar system. There are 8 planets. Mercury,Venus,Earth,Mars,Jupiter, Saturn,Uranus,Neptune.

Actually, at first it  was 9 planets because of Pluto. But,now it doesn't exicts.

Earth is the planet that people and animals can live well becase, it has the right temperature. I also learned about the Earth's  birth.

About 14~15 billion years ago, the big bang happened and 4.6 billions years ago the Earth was borned. Lastly, I learned about the movemants of continents.

The continents were all connected in one land. It was called Pangea.

Later and later it got seperated by 6 continents. When I learned all of these things,

I felt very happy and excited. I got intrested at natural history.

If I have a chance I want to laern more about them.
