When you hear the term "Earth art," your mind probably goes one of two ways: art depicting the Earth, or earth being used to make art. If you thought of the latter, you're spot on. Intro to Earth Arts: Cultivating an Ecological Perspective, an art course through The Gem Center for the Arts, will teach the history and practice of earth art to beginners. Students in the four-week course will participate in activities, projects and discussions, and experiment with natural materials (think rocks, mud and other earthy items). The class will also teach students the proper vocabulary for discussing and critiquing art in a constructive and meaningful way.
