Element Day for the Seventh Grade: a tradition in its 15th year! The seventh graders came to school in full costume as an element from the periodic table in order to deepen their understanding of periodic trends and atomic bonding. The girls prepared completely homemade costumes from reclaimed and recycled materials that reflected 15+ properties of their element. These properties included, but were not limited to, electron configuration, reactivity, material science, classification as either metal, nonmetal, or metalloid, and many unusual, and often unknown, uses!
