With this interactive collection from the Exploratorium, you can explore sound through auditory illusions, acoustic phenomena, and other things that go bump, beep, boom, and vroom. This app features nine interactives, videos, and articles that cover topics from speech recognition to the emotional impact of musical scales all in an effort to help you explore the science of sound.
The app opens to a table of contents that you can use to jump to any chapter of the app by tapping its link. Or you can swipe through the app page-by-page. Also, if you're on a certain page and decide you want to jump to a different one, you can double tap on the screen and a navigation bar will open at the bottom of the page.
Currently, there are 15 chapters. Each chapter consists of a nicely laid-out page with several interactive elements. For example, the chapter called "Hear 'n There" asks you to listen to a bedtime story given in various locations. It's your job to try to guess what kind of place you think it is. Can you guess?
Some of the other chapters include: Find the Highest Note, Eyes vs. Ears, What's Making This Sound?, and How Old Are Your Ears?
Designed like an interactive magazine, the Sound Uncovered app can be especially useful for physical science and physics classes. You can use it to enhance a classroom unit on sound by allowing students to touch, see, and hear the scientific phenomena they are studying in class. Any of the mini-lesson activities can be used to launch a lesson in the classroom. For example, in one of the activities students are asked to listen to a sound with their eyes open and then to listen to it again with their eyes closed. Did the word sound the same?
The individual chapters in the app also could be used as general overviews of the concepts presented and to pique your students' interest. From there, your students could conduct more in-depth research on the concepts and then prepare presentations for you and the rest of the class.
