Junior High students spent some time learning a value scale and had to complete a multi-gray scale done in ebony or 4B pencil before starting a design. Many of the students at this age are not used to keeping their hands out of the way when they are working, and they didn't quite get into the habit of laying down a scrap sheet to protect areas previously worked. We had no windows, nor could students leave the room to go outside, so spraying was not feasible. They did their best and most did grasp the idea of value and blending, though mastery wasn't gained in their initial pieces. (See Animoto below)
