When an apple falls on his head, Newton the squirrel begins to wonder how the world works. After perching on a branch outside a classroom window and listening in on a lesson about the force of gravity, he decides to try his own experiments with the help of his sister, Curie. Learning to make simple machines, they discover that science is for everyone—even squirrels. And when a birds’ nest falls out of a nearby tree, only Newton and Curie, using their inventions and quick scientific thinking, can save the day! This latest from bestselling author Daniel Kirk is a light introduction to the principles of STEAM (science, technology, engineering, art, and math), which is taught in schools. Applying what they learn in class, this always inquisitive and resourceful pair solves reallife problems and has fun along the way. Together, they’re always hungry for knowledge—and nuts!
