I don't think that we give kids enough credit. Look at this; a small cut-out from a magazine and those creative juices just a flow. What a wonderful project for any age child to do. Older students can start with a small clipping and younger ones can have a larger clipping; either way let them EXPLORE!
Ms Maggie Mo's Australian Aboriginal hand project: spray hand with thinned white or black tempera, student paints dots with sticks. I showed 1988 Nat Geo Aborigine video of Gagadju Aborigines blowing paint from mouths over hands as part of ritual. Awesome video also shows artist making intricate bark painting.
