Sinagua were a group of people who lived a long, long time ago in what is now known as Northern Arizona. They were called Sinagua which means "without water" because they lived in a place where there wasn't a lot of water, so they had to be very careful with the water they had.
The Sinagua were really good at farming and growing things like corn, beans, and squash. They also hunted and fished for food. They lived in homes made of a material called adobe, which is a mixture of mud and straw.
The Sinagua were known for their beautiful pottery and jewelry. They would make these things by hand and then decorate them with pictures of animals or patterns.
Unfortunately, we don't know a lot about the Sinagua because they lived so long ago, and many of their belongings have been lost or destroyed. However, we can still learn a lot from what they left behind, and they are an important part of Arizona's history.
