Space craft has to do with aliens! I saw these cute alien handprints over at Red Ted's Art Blog. As each child got dropped off in the morning, I painted their hand. They got to choose how many fingers would be painted. Within an hour or so they were all dry and the kids could add wiggle eyes and draw the rest of their alien.
here. They aren't the cheapest books (my brother donated a bunch to me and other family members), but maybe you can find them in your local library.
I hope you enjoyed my space unit!
