In my Friday art class my main goal is to get the students thinking outside the box as far as materials go. We are making figure sculptures, the base of which is cardboard and wood. I was inspired by a book I saw recently by Keri Smith with a lot of art experiments, Wreck this Journal or something like that it was called.
So first we had 2 minutes to attach pieces of colored paper together using traditional techniques- glue, tape, etc- and the challenge to find something non-traditional.
Then, we talked about homes which have junk drawers and I piled a bunch of stuff from mine on the table and they had 2 minutes to create a person out of them.
Now, that class was 5 of 8. I wish I had been doing this since day one!
