major museum addition on October 11, 2013 called the Bezos Center for Innovation. The project is funded by a $10 million gift from Amazon.com founder and CEO Jeff Bezos. The project was designed by Seattle-based Olson Kundig Architects and occupies a portion of the museum's Grand Atrium. Education programs The K-12 programming at MOHAI is designed to complement the permanent exhibition, "True Northwest: The Seattle Journey". Programs are designed to support teachers through meeting state curriculum standards, and offering professional development opportunities; use primary sources to promote critical thinking; present multiple perspectives to explore diverse experiences and histories that make up Seattle's story; make history relevant with personal connections; and create links across academic disciplines. Onsite programs for students are designed to complement the permanent exhibition. Students use primary sources to explore Seattle's stories, gather evidence to crack history mysteries, and explore facts and myths about Seattle's past. Outreach resources include themed trunks that include artifacts, audio/visual resources, and adaptable activities that are aligned to state curriculum standards. Themes range from Native American People of Washington State, to the Settlers of Washington State, to the War Years. Themed packets of visual resources include photographs and slides, background histories and activities. Themes include Early Recreation in Seattle, Changing Scenes of Downtown Seattle, and Women in Washington History. Finally, a reader's theater script, drawn from primary sources relating to the Gold Rush, comes with stage directions. MOHAI also organizes professional development opportunities for teachers, to strengthen their understanding of Seattle's history, object-based learning, and curriculum standards. Collections MOHAI has around 4 million objects in the collection, including roughly 100,000 three dimensional artifacts, over 3 million photographs, and around 200,000 archival holdings. Collections focus on Seattle's early settlement (ca. 1850) through the present day, and concentrate on the stories and achievements of Seattle and King County residents. The three dimensional collection encompasses a range of items such as textiles, fine art, decorative arts, household objects, maritime equipment, early computers, vehicles and more. The museum also has a growing collection of oral histories from long-time Puget Sound residents. Photograph collection The most heavily used portion of MOHAI's holdings is the collection of approximately 3.75 million historic photographs, which is the largest aggregation of historic documentary photography in the region. Like the rest of MOHAI's collections, the photos are primarily focused on Seattle and King County, but includes strong coverage of other parts of Washington
