Just before her 12th birthday, Calpurnia Tate, or Callie Vee, isn't quite ready to become a grown-up in her Texas town in 1899. Especially if it means doing housework instead of the scientific work she's been doing with her grandfather. At the book wrap, we will be joined by Jessica Shearer, an ornithological researcher at the American Museum of Natural History. We'll talk about what it meant to be a woman at the turn of the 20th century, the beginnings of evolutionary biology, and women in science today. Free with admission, ages 9-12 plus adults.
