Deep down in the depths of the sea, beautiful fish, mysterious ocean life, and unusual plants glimmer and glow in the eerie atmosphere of an ever-changing ocean. This article describes how, with this vision and a purpose in mind, three teachers pulled open classroom walls and joined forces so their second graders could create a mammoth 30 x 75" (76 x 190.5 cm) glow-in-the-dark ocean environment. Students were awestruck with their collaboration, as they walked through the ocean environment, beautifully lit by black lights, and employing a variety of different media techniques to create creatures and plants that dwell in an ocean environment. "Ooooh's" and "Ahhhh's" echoed throughout the room. Hundreds of delighted parents, family, staff, and district educators waited in line to tour the ocean while enjoying the soundtrack from Under the Sea.
