Today, I go to the Seodaemun museum of Natural History.

I saw a nine planet.

It is Marcury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

Marcury is smallest and Jupiter is  bigest.(Jupiter is king of the sky.)

We live in the earth .

Eaarth had oxygen, so we can breath and we can live.

Then I saw a dinosour, bacteria.

Bacteria is very small, so we can't see it. Cyanobacteria is one of them too.

Cyanobacteria is living cells that produce oxgen through photosynthesis.

And, I saw a dinosour.  Dinosour is very, very big!

But today, dinosour is died.

Because the big rocks fall to the earth and volcano, so many dinosours is died and few of them is safe.

Valcano is opening in the earth's crust through wich magma is ejected.

I saw many things and learn many things in museum of natural history.
