Sound Waves

"These titles feature objects and processes that will be familiar to students, such as video games, cell phones, and GPS. The connection of each type of wave to kids' everyday lives makes the content relevant to young readers. Photos and diagrams depict bats using echolocation, the formation of rainbows, weather radar, and other examples of waves in action. Each book ends with directions for an activity to explore the concepts covered. Students might experiment with trying to block the signal to a radio-controlled car or making music with glasses of water. The series could be read to first graders or explored independently by older students. VERDICT A solid introduction to the concepts; a good addition to collections."
