Sound Uncovered is a free iPad app from Exploratorium. In Sound Uncovered students can explore a series of interactive activities to learn about how sound travels and what makes us perceive sounds the ways that we do. Some of the highlights of the app are Find the Highest Note in which students play a series of notes to determine if there is a highest note (spoiler alert: there isn’t, but your ears will tell you otherwise). How Old Are Your Ears? is an interactive that explains why we lose hearing as we age. The Beat Goes On. And Off, And On… is an interactive in which students play a couple of different notes and learn how those notes are used my musicians to tune instruments.
Sound Uncovered could be a great application not only for music classes, but also for science lessons.
