Ceramic Owls - Thumb Method Lesson - Fun & challenging project that my After School Art Class grades) just did. We used the thumb clay technique (with some modifications) used on Artsmudge's Clay Owls.
Mrs. Tabitha Seaton - OpArt Hands I needed an art activity for teens and found this. Unfortunately, not many teens showed up, but there were a lot of kids and they really enjoyed this activity. It also looks amazing once it's done.
Tinfoil people 3-D art lesson. Fantastic art lesson for students that let's their creativity shine. Lots of differentiation opportunities available. This would be great in a middle or high school special education art classroom.
