Get in Gear, the first book in the groundbreaking Hands-On Science series, takes the concept of transferring motion through the use of gears and presents it in a kid-friendly way! Guided by Doc Sprocket, a robot who lives in a junkyard, kids can build wacky gear contraptions directly on the pages, using real gears that are stored in a special tray at the back of the book. Once the gears and parts are in place, switch on the built-in motor and watch the gears move. On the last page, kids can use their imagination and build endless contraptions of their own! Open Get in Gear and find: · A real electric motor with replaceable batteries

· 19 working gears and parts

· Loads of contraptions to build

· Color-coding for easy assembly

· Simple-to-read text

· Amazing facts about gears

· A Planetary Picture Producer to make spiral designs
