In this fascinating title, readers explore how light and sound waves transfer information. From telescopes that extend our sense of sight to satellites that help us communicate across large distances, patterns of waves transfer information in many ways. A link to interactive activities online plus an activity in the book allow readers to use what they have learned about waves to engineer wave patterns that communicate across distances. Teacher's guide available.

This exciting title introduces readers to the concept of a wave and the patterns and properties common to both light and sound waves. Clear text and detailed diagrams combine to demonstrate the cause-and-effect relationships involved in the properties of amplitude, wavelength, and frequency. A link to interactive activities online plus an activity in the book allow readers to explore key concepts close up by creating their own wave models. Teacher's guide available.
