We started this off by looking at the work of Alexander Calder. We talked about the shapes, colors, dimension, balance and movement of his mobiles.
To practice tracing around an object, we traced around our hands. They needed to incorporate at least four hands into their piece and a total of at least ten shapes. Other than that the only thing they had to show me at the end was a balanced mobile. We used two Popsicle sticks glued together to hang everything else from and pipe cleaners to add depth and attach our shapes.
