Need ideas for collaborative class art projects K-8th grade to auction--have done themed scarecrows in past yr

Question

Project needs to be one complete item containing a contribution from each child (art or photo, etc) per class and inexpensive. Will be auctioned off in autumn.

Answer 1

Have a contest to see who can create the best art using plastic spoons/forks/knives. Perhaps also including picnic plates.

Let their imagination go wild. It is possible you could even see robots, or 3-D art. For starters, look at "plastic art" images on your search boxes.
