Book Description
With colorful illustrations and engaging text, Phones Keep Us Connected is a fascinating look into the science, technology, and history of how phones work!
Before telephones were invented, there was no way for you to sing "Happy Birthday" to your friend if she wasn’t in the room with you. Now you can call anyone, anywhere in the world! How was the phone invented? How has it changed? Read and find out how a telephone can carry your voice across oceans, and how phones have changed the world.
Featuring rich vocabulary bolded throughout the text, this book includes a glossary, a find out more section with an activity about building a string telephone, and an infographic about the history of the phone. Both the text and the artwork were vetted by Dr. Jerry D. Gibson, Professor of Electrical and Computer Engineering at University of California, Santa Barbara.
This is a Level 2 Let’s-Read-and-Find-Out Science title, which means the book explores more challenging concepts for children in the primary grades and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards. Let’s-Read-and-Find-Out is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.
Booklist *Starred Review
A well-explained, informative presentation on the telephone’s historical development as well as how cell phones work…Featuring a diverse crew of characters, the upbeat digital illustrations are attractive and, equally important, very helpful in showing hard-to-visualize concepts. |
