Landscape architects combine knowledge of art and science to plan, design and manage natural and built environments. Teachers will begin their exploration of the work of landscape architects at the United States Botanic Garden (USBG) with behind the scene tours led by a USBG landscape architect and conservation horticulturist.  After getting a sneak preview of the recent conversion of Bartholdi Park to a sustainable site, teachers will venture into the National Garden as it celebrates its tenth year and explore its design and the native plants of the regional garden.  Teachers will engage in hands on soil and water conservation modules at the USBG before walking to the National Building Museum. At the Museum, participants will continue thinking about sustainability and work to solve a landscape challenge by considering how to use structure and plantings to create a sustainable design.
