Spring Flowers. "Students used white tempera paint to design their vase and bouquet. They learned how to use their brushes to "dab" the flower petals on and how to use the end of their brush to create a design on their vase while the paint was wet. When the paint was dry, they added color with chalk pastels. Emphasis in this lesson was placed on the design principle of repetition." Melvin Avenue Elementary. Artsonia.
