Bluetooth devices use radio waves from a small computer chip to connect. When one Bluetooth device comes close to another Bluetooth device, they send radio signals to one another—with no wires, cables, or cords. This amazing technology allows you to take computers, game devices, and many other objects from room to room. This book will allow students to use tools and materials to design and build a device that uses light or sound to solve the problem of communicating over a distance.

Filled with full-color photographs and reading comprehension activities, this book effectively engages students and complements the research of how an important piece of technology works. Bluetooth allows students to make observations and gather information about a simple problem that can be solved through the development of a new or improved object or tool.

Each 24-book features a teacher-focused concept, before- and after-reading activities, a photo glossary, and more, for a well-rounded understanding of the topic. The How It Works series lets young readers explore and research the technology and design of important, everyday things and how they are engineered. With simple-to-follow text and full-color photographs, these books easily engage young learners to discover the inner workings of complex objects and concepts.
