How do archaeologists determine where to dig?

One of the questions that my students ask most is-"How do the archaeologists know where to dig?" That's a great question, and one I had myself. I asked one of the grid supervisors, Dr. Tracy Hoffman, to tell me how this is done. She let me know that archaeologists use the scientific method to not only find where their next dig site will be, but also what to uncover in the grid once they start digging. Listen to her tell more about it below.
