This easy-to-follow book allows young learners to explore the inner workings of speakers.
Speakers have only one job: to deliver sound! Whether its your iPod®, radio, or television, without speakers, you wouldn't be able to hear anything. From currents to magnets, coils, cones, amplification and volume, all of the intricate parts of a speaker are addressed in this book. This title will allow students to plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate.
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. Speakers 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-page 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.
A solid overview of the mechanics behind each machine. By including such high-interest topics as roller coasters, wave pools, and drones, this latest installment will undoubtedly inspire inquisitive minds to seek out other titles in the series. Advanced scientific concepts, including centrifugal force (Cotton Candy) and aerodynamics (Drones), are simply explained so that readers gain a basic understanding of the processes, engineering, and design without being overwhelmed by details. Interesting tidbits, such as how roller coaster designer Ron Toomer never rode any of his creations due to his severe motion sickness, are sprinkled throughout the text and offer specifics that are fun and memorable. In terms of design, the large black print stands out on crisp, white pages, while full-page photos are attention-grabbing. A photo glossary, complete with pronunciation, reinforces concepts and provides a satisfying conclusion. VERDICT A must for all children’s nonfiction collections. < p>
