I'm sure you've gotten the question at some point from a student or wondered aloud yourself: "What did the people who lived where I live eat 3000 years ago?"
Almost universally, it was taught that ancient Ohioans ate corn, beans, and squash as their main domesticated crops, known as the "Three Sisters." We now know that was wrong!
Over the last 30 years, scientists have discovered a bevy of plants once thought of as annual weeds that were domesticated by the people who lived in this land. Between about 2000 and 1000 BCE, communities in Ohio's river valleys domesticated sunflower, squash, goosefoot, and sumpweed, then folded in maygrass, erect knotweed, and little barley. This was the Eastern Agricultural Complex, a group of domesticated crops that were grown and harvested seasonally together. Corn and beans arrived late and spent centuries as a minor character. That makes Eastern North America one of roughly ten places on Earth where people invented agriculture from scratch. And the first farmers in what became Ohio bred their harvest out of the plants that now grow through the cracks in your school parking lot!
Botany calls them weeds today, but for 3000 years (from around 2000 BCE - 1000 CE), they were the main harvest of Ohioans. One rockshelter in the Hocking Hills held a goosefoot cache that Bruce Smith estimated at nine million seeds, the largest store of native domesticated grain ever found. In 1998, an Ohio University field school dug into a low rise where Sunday Creek meets the Hocking River and found the leftovers of a very large dinner from around 2000 BCE. There were five cooking pits, some big enough to feed 60 people in one sitting. Sifted out of the ash, by the thousand, were charred seeds of goosefoot, marshelder, maygrass, and squash.
This week's lesson puts your third, fourth, and fifth graders to work as chefs in Ohio's oldest restaurant. The will learn the real ingredients, real cooking methods, and a menu that predates the entire Bronze Age of European history. Along the way they will learn heredity (seeds change when you keep planting the big ones), geography (rivers make farmland), and a little humility about the word "weed.
