Household archaeology is like playing detective in your house! Just like how a detective looks for clues to solve a mystery, archaeologists look for clues about how people used to live in their homes.
To do this, they dig up the ground around old houses and carefully brush away dirt to find things like old pottery, tools, and even garbage. By looking at these things, they can figure out what kind of food people ate, what they did for work, and what kind of things they used in their everyday life.
It's like going on a treasure hunt and trying to put together a puzzle to learn more about how people used to live a long, long time ago. And who knows, someday someone might be digging up the ground to learn about how we lived today!
