Soundboard

Soundboard.com is the Internet's largest catalog of audio soundbites and categorized soundboards - from history to sound effects, movies to games. You can listen, download tracks and embed boards on your site, blog or profile. 

You can create a soundboard for your class and share the link in the chat box, like this: http://www.soundboard.com/sb/mssheltonsclass 

OR

You can share someone's soundboard, like this:

My favorite thing to do is to have this link open on my monitor during Class Connect sessions. I just press the play button, when my mic is turned on, and use the sound effects to make class more interesting. The kids LOVE it!
