Years ago, I saw an image of many sets of eyes painted onto strips of wood. They were all mounted together on a gold colored wall. It was really impactful. I have long wanted to do a lesson like the one I saw. This is what we came up with.
Each student was given a small mirror to observe their eyes. We discussed shape and characteristics of eyes: upper lid, tear ducts, lower lid, eyebrows, etc. etc. We thought about proportion-the face is 5 eyes wide; eyes are one eye width apart making observations about the human face. We talked about how eyes express emotions. Students then used oil pastel to create these images.
