Adena culture is something that happened a very long time ago, before you, your parents, and even your grandparents were born. It started around 1000 BCE and lasted until 200 BCE. This is a long time to be around, right?
During this time, people from the Adena culture lived in what is now the United States of America, specifically in the Ohio River Valley. These people were very good at making things out of materials they found in nature, especially rocks, shells, and bones.
One of the most amazing things that Adena people made was called a burial mound. This is like a hill made out of dirt and stones. When someone from their community died, the Adena people would bury the person in the mound. Sometimes they would also put special items in the mound so that the person who died would have these things with them in the afterlife.
The Adena people also liked to make pottery. Pottery is like a bowl or a plate that you can eat food from. They made these bowls and plates by using clay from the earth and shaping it into different shapes. They would then bake it in a fire to make it hard.
In addition to making things, the Adena people were also good at farming. They would grow plants like corn, beans, and squash. They would use these plants to make food to eat.
So, in short, the Adena culture was a group of people who lived a very long time ago in what is now the United States of America. They were good at making things out of materials found in nature like stones, shells, and bones. They made burial mounds and pottery, and were good at farming to grow plants to eat.
