Assignment #5 Audio and Earth Day


For Advanced Students:  April 22nd is Earth Day.  Please create a 30-second video Public Service Announcement for Earth Day and how we can take better care of this precious resource we call home.

Here are a couple websites that can help you:

This is due, on...you guessed it...April 22nd!

For Beginning Students
There is so much to learn about audio!  I just wish I could see you all in class so I can demonstrate and show you all that I want you to learn about microphones and audio.  This Power Point will have to do.

Please take a look at (and listen to) this Power Point and then please work on filling out the worksheet below.

Submit the worksheet to me via Google Docs and be sure to turn Link Sharing "On" and get a "shareable link" to send to me.  Otherwise, I won't be able to see your work and grade it.

To get credit, please turn this in to me by Wednesday, April 22nd.
