In Do Elephants Have Knees?, Charles R. Ault Jr. takes a unique approach, bringing together juvenile literature with a wide range of literature from science, history, education, and psychology. This is an important work for science education because the author weaves together scientific knowledge with the appropriate historical context. This book will find an audience not only among science educators but also among well-educated and curiosity-driven general readers who thrive on connections among disciplines."
