Places (sites) are chosen often because some evidence has been found by accident. Archaeologists look carefully at (survey) the site and mark on a map anything they notice. Sometimes they use special equipment to help them 'see' underground. They will also check if anything has already been found out about the site.
If the archaeologists decide to dig (excavate), they remove the soil, and look for evidence. All the evidence for houses and other finds is drawn on to a plan. Smaller objects like pottery, tools, and coins are taken away so that experts can look at them. They can often tell us how old an object is and how it was made. When all the investigations have been finished, the director of the excavation writes a report. The report says what was found, and what the evidence tells us about the people who lived on the site in the past.
