What do archaeologists do?

I was reading the rest of our first chapter in our history book, Story of the World. This chapter is an introduction and it has two parts: What is History? and What is archaeology? Today I read the archaeology part and asked a couple of review questions. Julia was sitting on the couch beside me and Karley was eating her apple, off to the side. I asked the first question, "What do archaeologists do?". As Julia is pondering her response Karley chimes in with, "They eat!" Gotta love that girl!
