Last Chance! Science Central’s spring touring exhibition, "Expedition Earth," will be on its final weeks of display through Sunday, May 10, 2015. Based on the popular book series, Adventures of Riley®, "Expedition Earth" invites visitors to experience life as a scientist on location at one of three featured biomes: grasslands, tundra, and forests. Visitors will experience first-hand the habitats, eco-systems, wildlife, diversity, and adaptations within each unique environment and learn techniques used by real scientists to help save the planet’s ecosystems. "Expedition Earth" was created by NRG! Exhibits and Eaglemont Press.
