UW Aquatic Sciences Open House
The 2026 UW Aquatic Sciences Open House will take place on Saturday May 16th at the Fisheries Science Building at the University of Washington! The event is organized by Students Explore Aquatic Sciences (SEAS) and hosted by the School of Aquatic and Fishery Sciences with support from the School of Oceanography and the School of Marine and Environmental Affairs. We invite you to join for this year’s event!
The Open House offers a free and family-friendly day of hands-on learning to celebrate science and research that relates to water. Visitors can step on board a research boat used for local science, and experience real working science labs here at the university. We also have hands-on activities led by current UW students, staff, postdocs, and faculty across the College of the Environment and by organizations from the greater Seattle area.
Come get your hands wet and learn about the aquatic science happening right here in your backyard—covering everything from freshwater to oceans, microscopic microbes to whales, and everything in between!
