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 · Create your own original designs · A handy tray to store all gears and parts
