Today, we went to Amsa-prehistoric museum. I saw many comb-pattern potteries and other tools. And I learn many things about prehistory age and stone, bronze, and iron age. People call the period before written records is Prehistoric Age. Prehistoric age is divided into three parts; stone age, bronze age, and iron age. Our Korea's first country, Gojoseon is made in B.C 2333 in bronze age. This 3 ages use each material, the name of their age.

 First, in stone age, there are paleolithic age, and bronze age. Paleolithic age is also called old stone age. Neolithic age is called new stone age. Paleolithic use stone tools by crushing. They use hand zx and other tools to hunt. Neolithic people use polishing tools for hunt and farm. I was very surprise about old people's knowledge and wisdom.

 Next, there is a bronze age. Bronze age people use bronze. They use bronze tools for showing their position and making a war. In bronze age, people have laws and classes and their own money and food. So, people fight and get the food from other people.

 Finally, there is a iron age. In iron age, people use iron and for fighting. Like bronze age. Bronze and iron age, both made weapons like sword and arrows for fighting. Iron age's tools are more developed than bronze and stone ages.

 I think this experience help me learn many things about out humankind and our ancestors. Also, I learn about our first history well.
