Have you ever been to National Museum of Korea? On Tuesday, I went to National museum of Korea.

I learned mant periods.

First, there was Ice Age. Ice age was the first period that humans walked upright. On Ice Age, people lived in caves.

Second, there was Neolithic period. After the Ice Age, people began living in house and live together. They lived near the sea of fresh water. On Neolithic Period, they fish and farm to eat.

Third, there was Bronze Age. On Bronze Age, people became advanced. They mad bronze daggers. The blade and grip were made separately.

Thank you!
