You go over to the construction site on your bike to ride through the dirt piles. When you get to the top of the biggest pile, you notice a sunken, round area in the soil. You've heard your mother talk about the fact that a house was on the property a long, long time ago, but you're too young to remember any house. You ride your bike home to get a shovel, since you want to see what might be left from the old house. You dig where the soil is a different color in the sunken area.
Artifacts begin to turn up a after a short while.
Even though you're tired, you keep digging, looking for more artifacts.
