K-Gr 3—An up-to-date history of communication, from telegraphs and Morse code to radio waves and cell phones. With the assistance of cheery, bright illustrations and diagrams, the author explains concepts such as sound waves, radio waves, and frequency—and how these work to make communication possible. Zoehfeld explores how early discoveries and inventions, such as the telegraph and telephones, led to modern innovations. Encouraging readers to write down ideas and draw sketches, the book is an invitation to think about past breakthroughs in new ways. Small print and the inclusion of scientific concepts make this a challenge for independent readers, but a glossary is appended, defining words highlighted throughout. A short time line illustrates how the covered devices have evolved over the years.
VERDICT A good resource for classrooms and independent researchers.
