Hi my name is Irene.

Nice to meet you, and today I'll talk about Museum of natural history.

Now, let's go in my story.

Are you ready?

Let's go!

 We live in Earth.

Isn't it?

And the Earth is one planet of universes.

There are 9 planets they surround the sun.

They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

So, you can see the Earth is third of it.

 In night we can see a small horoscope.

Maybe, we can't because today's night was so bright.

But in the country side, we can see the horoscope.

I live in seoul, so I can't see horoscope, but whan I was in Pyeongchang, I can see horoscope well.

 There was four period in Earth.

That was Precambrian Era, Paleozoic Era, Mesozoic Era, and Cenozoic Era.

There is some living thing in this Era, I will talk about it.

 First, was a Precambrain Era.

In this Era, a cyanobacteria was lived in earth.

It was a living cells that produce oxygen through photosynthesis.

It was a first living cells in Earth.

 Next, was a Paleozoic Era.

In this era, amphibian and reptiles were lived.

Than I can think about the dinosaur's ancestor was reptile and amphibian.

 And there was a Mesozoic Era.

In this era, a dinosaurs lived in.

There was a three types of dinosaurs.

It was carnivore omnivore, and herbivor.

 Lastly, there are Cenozoic Era.

In that period, we lives in a Earth.

Thank you for watching in my essay.

Bye!
