I love this project for 2nd grade! We talk about perspective, fore, middle and background. The students start with painting the sky, we add white to the blue for a tint. Then the students mix the two compliment colors blue & orange to get a nice brown color for the stems. Once dry the students add details to the pumpkins to make them look round and some crows in the sky. We construct our scarecrow as a class and glue him to the paper. They turn out really successful! I saw this a few years ago on a school art webpage.
