I have taken 2 e courses from Patty Palmer's Deep Space Sparkle. This is one of Patty's projects. My Fourth graders created these versions of Arches National Park. The park is not too far from where I teach and most students have been there.They were very excited to draw the arch. We learned about Prickly Pear Cactus, Agave, and Yucca. One class used oil pastels on white tag and watercolored over. The other classes used chalk on brown construction paper, using a black pastel to outline.
