OMSI has five different specialized exhibit halls, a planetarium, and a submarine exhibit.
USS Blueback at rest on the
Willamette River in front of OMSI. The
Marquam and
Hawthorne bridges are in the background. The was purchased by OMSI in February 1994. This
submarine appeared in the 1990 film
The Hunt for Red October before being towed to its present location, a pier adjacent to the museum. It was opened to the public on May 15, 1994, and was added to the
National Register of Historic Places in September 2008. The propeller is a National Submarine Memorial located outside of the main museum area, beside the
Eastbank Esplanade. The submarine is available for daily guided tours and sleepovers.
Featured Exhibit Hall The Featured Exhibit Hall is used for temporary exhibits created by OMSI or those brought in from museums around the world. Past exhibits have included "Grossology" (Winter–Spring 2001), "Giants of the Gobi" (1997), "A T-rex named Sue" (September 2001 – January 2002), and "CSI: The Experience" (May–September 2009).
Gunther von Hagens'
Body Worlds 3, opened on June 7, 2007, and closed on October 7, 2007. By late September 2007, the exhibit had received 300,000 visitors, setting the record as OMSI's most visited traveling exhibit. In September 2015, OMSI hosted the
National Guitar Museum's exhibition "GUITAR: The Instrument That Rocked the World."
Turbine Hall The Turbine Hall is named for the large retired
steam turbine from its days as a PGE power plant. It features exhibits about engineering, physics, chemistry, and space travel. The Turbine Hall has two floors. On the main floor are the large exhibits and enrichment areas. On the mezzanine there are smaller exhibits. The Innovation Station includes hands-on exhibits related to technology and invention. Laboratories for physics, chemistry, technology, and laser
holography are connected to the Turbine Hall. The Chemistry Lab is the first hands-on wet
chemistry laboratory in the nation. There are six stations that allow visitors to learn about chemical interactions by participating in experiments that share a common theme. Themes rotate weekly and include the chemistry of toys, the nature of matter,
biochemistry, environmental chemistry, industrial chemistry, chemical reactions, everyday chemistry, and crime scene chemistry. Chemical reaction demonstrations are given daily and are often related to the weekly theme. Physics Lab exhibits include a
Van de Graaff generator (a static electricity generator), motion detectors, electrical circuits,
Morse code, magnets, computers that simulate basic properties of physics, and musical instruments. The Laser/Holography Lab, which is open for approximately one hour every day, presents 30-minute demonstrations constructing a hologram. The Vernier Technology Lab investigates the impact of technology on society. Rotating interactive exhibits allow visitors to investigate technologies such as robots and computers, security technology,
biomedical technology,
communications technology, and household technology. Visitors can also use a wide variety of educational software on internet-connected computers.
Life Sciences Hall The Life Sciences Hall, on the second floor of the museum, offers exhibits about biology. These include a collection of preserved fetuses at nearly every stage of development, from a few weeks after conception to full-term, and the exhibit Amazing Feats of Aging, which is concerned with the biology of aging. One of the features of this exhibit is the Age Machine, a computer program that allows visitors to capture and then "age" a picture of themselves. The Life Sciences Hall also contains the Life Science Laboratory and the Earth Science Hall. The Life Sciences Laboratory houses a wide variety of live animals, such as rats,
walking sticks, chameleons,
Madagascar hissing cockroaches, other mammals, reptiles, amphibians, and insects. Volunteers and staff members demonstrate and lead a variety of a group activities such as owl pellet dissections and exploration of the differences between male and female skulls and pelvises.
Earth Science Hall The Earth Science Hall, located on the second floor, features geology-oriented exhibits and two specialized laboratories. The Watershed Laboratory gives visitors an experience in constructing an erosion cycle out of a physical model of a river. Visitors can learn about the life cycle of
salmon and investigate microscopic organisms from local waterways through a video microscope. Visitors to the Paleontology Laboratory watch staff members and volunteers excavating fossils, such as dinosaur bones.
Science Playground The Science Playground, in the early childhood education area on the second floor of the museum, is designed for families with newborn to six-year-old children. The area is fully enclosed and designed to keep children visible and secure, while giving them freedom to explore at will. Its purpose is to give children the opportunity to develop interactive scientific learning through play. It contains a variety of experimental stations intended to encourage natural curiosity including a stimulating infant area, a giant sandbox, a water area, a reading area, and physical science exhibits. The area is staffed by trained specialists in early childhood education. There is also a Parent Resource Corner with reference materials on topics ranging from the developing brain to behavior intervention techniques. The Animal Secrets exhibit encourages children and parents to explore the hidden habitats and lives of forest animals. Visitors can crawl through the roots of a discovery tree, look for animals in a cave and a chipmunk den, play in a woodland stream, and be a naturalist for a day. Animal Secrets features English and Spanish text panels. The Discovery Laboratory offers rotating experiments and activities such as exploring Flubber or ice cube painting. Themed Discovery Drawers encourage parents to teach their own children about the contents. OMSI is a member of Nanoscale Informal Science Education Network, and participates in NanoDays.
Planetarium Computer-aided astronomy and laser light shows are performed daily in the Harry C. Kendall Planetarium (previously the M. J. Murdock Sky Theater).
Best Buy Teen Tech Center On February 1, 2020, the Best Buy Teen Tech Center opened. As a partnership between
Best Buy and
The Clubhouse Network, the Teen Tech Center is a free, out-of-school space for teens to explore their ideas, develop skills, and express themselves through technology. Available technology includes programming, filmmaking, music production, and graphic design.
Theory Eatery from inside the Theory Eatery, 2014|right Theory Eatery, or simply Theory, is an
American cuisine restaurant opened on January 30, 2013, as an addition to OMSI. Located alongside the
Willamette River in the Central Eastside Industrial District, the restaurant has of dining space. Mark Patel, former developer director of OMSI, was behind the creation of the restaurant, which is operated by
Bon Appétit Management Company. The restaurant is part of the museum, also offering exhibits, science demonstrations, and public and private events. In 2023, Theory reopened under Epicurean Group management. Theory is located off of the
Willamette River, with views of the
Tilikum Crossing,
Marquam Bridge, and the
downtown Portland skyline. In November 2013, the restaurant was redesigned, and included a new mural of photographed ingredients arranged with formulas in the background, designed by OMSI graphic artist Melissa Hicks. ==Auditoriums==
