Motion and Design contains stories about how the structure of organisms helps them function in nature, and how scientists and inventors develop and refine the design of devices we use every day. The book is written for 4th and 5th graders. In the first section of the book, students will learn how birds and insects fly and how creatures as different as flying squirrels and dolphins have unique features that help them move swiftly and efficiently in search of food and safety. There are also stories on how scientists and inventors—from the innovations of Leonardo da Vinci to the technological spoofs of Rube Goldberg—have developed an array of machines to help us move around on earth and in space.
