This paper focuses on how the arts heighten cognitive experiences through the use of natural materials and sites and the engagement with the natural world. The arts expose viewers to new ways of seeing, feeling, and thinking about nature; this can lead to greater awareness of and motivation to act on behalf of nature. The author examines the artworks of Nils-Udo, a German artist, by looking at his art-making processes, intentions, and themes. Using illustrations of several of his major works situated in various natural environments, the author considers how these artworks could initiate discussions and foster connections to classrooms while providing elementary and middle school students with opportunities to view and ponder existing artworks, create their own natural artworks, and heighten their ecological awareness.
