This was recently a very successful project for 3rd to 5th graders. I like the contrast of the soft watercolor against the crisp cut leaf edges.Week 1. Give the students two 9" x 12" sheets of paper and watercolor paints. Instruct them to paint one sheet with a green grass base and blue sky. Dabbing the wet sky with a dry paper towel can create a soft cloud effect. The remaining sheet is to be completely painted in splotches of warm colors - red, orange and yellow.
Week 2. Give the students a rectangle of black construction paper to cut out a tree trunk silhouette with branches on top and roots on the bottom. This gets glued to the blue and green (sky/grass) paper. The remaining splotchy paper gets cut into small triangle shapes and glued to the tree, sky and ground.
