Seen the Croods with your kids in theaters this summer? Want to give them a more science-based view of our early ancestors? Jerry Caple's new workbook "Sticks, Stones, Fire and Bones" is just what you need. Based on fossil records and informed speculation, Caple creates engaging stories of how apes and hominids might have evolved---then he asks the reader to speculate and experiment along with him. Complete with original artwork to bring the stories alive, the workbook is bound to engage you and your child in fascinating discussions. Could be a great summer project for a budding scientist!
