The large-scale installation Connected Worlds is composed of six immersive ecosystems spread out across the walls of the Great Hall at the New York Hall of Science. A 3,000-square-foot interactive floor and a 45-foot-high waterfall connect the ecosystems. Children use physical logs to divert water flowing across the floor from the waterfall to the different habitats, where they then use their hands to plant seeds of their choice. As their plants grow, creatures appear in the habitats based on the environmental health. Connected Worlds encourages a systems-thinking approach to sustainability where local actions in one part of the environment may have global consequences. With a fixed amount of water in the system, children have to work together to distribute the water across the different habitats.
