Resumen del Libro:
Sound waves are all around us creating a multitude of different frequencies. Some we can hear, and some we cannot hear. Discover the ways in which animals, insects, and birds communicate through sound as well as how sound is beneficial for other uses — even if we cant hear it! High-interest, informational text paired with vibrant images and photos, intriguing facts, and a helpful glossary and index will keep readers engaged from cover to cover. A Think Like a Scientist activity that supports STEM instruction is included at the end of the e-book for students to apply what theyve learned about sound.
