Hi, my name is Yuna. Last weekend, I went to a transportation museum with my grandma. Transportation is the way people and things get from place to place.
A guide told us that long ago, people walked to most places. They had to carry heavy loads on their backs, so trips took a long time. Later, people rode horses and sailed small boats on rivers. More than 5,000 years ago, someone made the first wheel. Carts with wheels could carry much bigger loads than one person could.
Next, we saw a huge black train engine. About 200 years ago, the first steam trains were built in England. They burned coal to boil water, and the steam pushed the wheels forward. Because trains were fast and strong, they could take many people and goods far away.
After that, cars and airplanes changed the way we travel. In 1903, the Wright brothers flew the first airplane with an engine. It stayed in the air for just 12 seconds, but it was a very big step. Today, huge airplanes carry hundreds of people across the sea each day.
Grandma smiled and said, "When I was young, the train from Seoul to Busan was much slower. Now the KTX can get there in less than three hours!"
In the future, more people will drive electric cars, because these cars help keep the air clean. On the way home, I wondered what kind of transportation my own children might use one day.
