In this engaging title, young readers learn about the form of energy that is sound! Sound waves and their wavelengths are discussed, as are the vibrations of molecules, acoustics, and how the ear interprets sound. These properties are illustrated by the making and hearing of music. Colorful infographics make decibels, amplitude, frequency, and ear anatomy easily accessible, and prominent contributors such as Ludwig van Beethoven are featured. A fun experiment with vibrations brings the science of sound to life! Aligned to Common Core Standards and correlated to state standards.
