Supporting NGSS, the Catch a Wave series focuses on the properties and uses of waves in our world. Clearly explaining the relationships between waves and their properties, each title helps readers explore how waves can be manipulated in order to hear, see, and understand information. Real-world examples, clear diagrams and vibrant images, and question boxes help readers make connections and understand concepts. A link printed inside each book gives readers access to Crabtree Plus, a website featuring supplemental digital content, including engaging simulations and interactive activities that reinforce and extend key series' concepts.
