In Lower Elementary, we looked at a few images of snowy landscapes-- both painted and photographed. We used compositional words: foreground, middle ground, and back ground.
For materials, we used a colored construction paper, then drew with colored pencils and white oil pastel.
After drawings were composed, I brought out yogurt containers that held home-made puffy paint! It's super easy to make--- it's equal parts shaving cream and Elmer's glue. Mix it and let it sit for about 5 minutes. (I made about a 8x12" pan full for approximately 50 total students.) Small paint brushes do work for application, but I think cotton swabs might be an easier clean-up solution.
The puffy-paint leaves a fun texture that is touchable!
For other projects with more possibilities, you can add paint or food coloring for a variety of colors.
