This easy-to-follow book allows young learners to explore the inner workings of speakers.
Speakers have only one job: to deliver sound! Whether it’s 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.
