Although I think all of your lessons are great, particularly those three, I have a soft spot for the claymation. I just think they are SO thoughtful, from beginning to finish. It's an art that is a little more unique than the typical things we do in the classroom, and I definitely think the students find it very memorable. My vote is for number 2!
Hmmmm. I'd go with either Oldenberg or the claymation. If not a lot of people do claymation, that might be considered most innovative. For the "Art" value, I like the Oldenberg.
