Description:
Lions roar. Birds sing. Babies cry. Telephones ring. It's hard to imagine what the world be like without sound. This title introduces middle school readers to the basic scientific principles behind hearing and sound. More than a dozen substantive experiments investigate vibrations, the properties of sound waves, pitch, volume, the anatomy of the ear, and more.
