When archaeologists complete an excavation, work in the lab begins. This is where they analyze their findings by carefully measuring, weighing, drawing, and comparing. They try to answer questions about when it was made and how it was used. They can learn even more by looking at objects found together as a group.

Archaeologists publish what they've learned in books and articles. They might support or challenge other theories. Most importantly, they're bringing new ideas to the debate. And that's what science is all about!
