It's a nice colored pencil/ shading/ teaching value lesson. Medium blue construction paper is used for background, and color is added with a darker shade of blue for the shadow side and white for the lit side. Students can choose any colors for accessories and snowflakes can be added in the sky.
Clay Owls- I did this with Kindergarten and 1st graders! It was very successful! They painted them with metallic acrylic. They fit on plate stands (that I purchased very inexpensively - parents reimbursed me). Everyone was thrilled! (They can get kind of thick - allow them dry for quite some time.)
