Have students recreate their own version of this owl with paint, chalk, watercolors, pastels, felt or mixed mediums.
Have them focus on layering lighter colors over the darker colors to create depth and practice smudging pastels to make the feathers looker softer or fuzzy.  You may also show the students how to create a grid over a printed version of this owl and then work on one grid section at a time on their own canvas or sketch paper.
