I love finding interactive books on iPad. This is a great resource to check out. It has videos and has fascinating questions that you can interact with!
If you don't have an iPad, then you can check out the website: Exploratorium: Making Sense of Sound
Found this video online that was connected to the sound wave: Top 5 Best Violin Dubstep
Low Amplitude=Low Energy=Quiet
High Amplitude=High Energy=LOUD

Richard asked this question in Physics class on Friday and we can make a very good connection between two things: empty soda bottles and windows with a draft.
Have you ever blown air across the opening of a bottle and heard a tone?
Something similar is happening in your window. Your window must have a small opening somewhere and as the wind blows across it, it makes a tone. You might notice that as the wind speed changes, so will the sound.
Lower wind speeds will produce quieter sounds while faster wind will produce louder sounds. There is a point where very, very low wind speeds will produce no sound. The wind has to blow at the right speeds in order for an effect known as resonance to occur.
The size of the crack in the window will also change the sound. Very small cracks will sound higher than very large cracks just as big bottles produce a big, low sound and little bottles produce a small, high sound.
The first song we listened to was a clapping excerpt in Nina Simone's 1964 song, "Sinnerman."
The following Youtube Video is one of the best version I found because it is the original version and it has lyrics. This song is loved by many people so that they often try to remix it. This song is not remixed. The clapping we heard in class starts around 4:00 minutes.
"Sinnerman" By Nina Simone
The next song we heard was in Engineering class. It was playing in the background of the Rube Goldberg Machine video from Teachertube: Billy Joel's 1989 hit, "We Didn't Start the Fire." Apparently Youtube has the original music video.
Lastly, when we were learning about the vibrations that happen in our faces in order to be able to sing, we heard Bob Dylan for the first time. We were discussing Bob Dylan because we were talking about how someone doesn't have to have a pretty voice to be a good singer. His voice is gravelly and coarse, but he sings on key/on pitch/on the right frequency.
Not only did he used to play guitar, but he sang AND played harmonica as well. Bob Dylan, "Live at the Newport Folk Festival."
