The Evolution of Calpurnia Tate

This is an okay book written by Jacqueline Kelly. The summer of 1899 is hot in Calpurnia's sleepy Texas town, and there aren't a lot of good ways to stay cool. Her mother has a new wind machine from town, but Callie might just have to resort to stealthily cutting off her hair, one sneaky inch at a time. She also spends a lot of time at the river with her notoriously cantankerous grandfather, an avid naturalist. It turns out that every drop of river water is teeming with life – all you have to do is look through the microscope! As Callie explores the natural world around her, she develops a close relationship with her grandfather, navigates the dangers of living with six brothers, and learns just what it means to be a girl at the turn of the century.
