You'll start by choosing a music documentary from the following list to watch in either a small group or as a whole class. These are all available on Netflix. You might want to take a minute and investigate each one before making a choice.
20 Feet from Stardom
The Wrecking Crew
Ain't In It for My Health
What Happened, Miss Simone?
The Other One: Long Strange Trip
Watch for 20 minutes and use this graphic organizer to Notice/Wish/Wonder about the content of the documentary as you watch. (You can print it off or make a copy that can be edited.) You might want to post those thoughts on your blog -- GREAT blog content!
Then you have the rest of class to work on design-a-band and blogging.
