Central Western Oregon Science Expo (CWOSE)

The Science and Engineering Fair for the Willamette Valley

Sponsored by University of Oregon

CWOSE is an opportunity for middle- and high school students in the Willamette Valley to engage in the process of science: asking questions, conducting experiments, collecting data, drawing conclusions, and communicating with others about their work. 

CWOSE is part of a large state and national system of science conferences.  The CWOSE science fair started in 2004 by David Hackleman, an Oregon State University engineer and has grown ever since. The science expo is a judged event, meaning that student projects are evaluated by teachers, college faculty and students, and significant  prizes are awarded to the winners. 

Who is eligible for CWOSE?  High school (grades 9-12) and middle school (grades 5-8) students in the following Oregon counties:  Yamhill, Marion, Linn, Benton, Tillamook, Polk, Lane, Lincoln, Douglas, Coos, Curry, Josephine, and Jackson.

When is the 2021 fair?   The next CWOSE will take place on February 27, 2021. The event will start at 8AM and will complete before 6 PM: The detailed 2021 schedule will be posted once ready.

Where is the 2021 fair?   The University of Oregon will  host CWOSE this year. If Covid Restrictions limit the fair, it will be held in a virtual format. Each year we plan to alternate locations between the University of Oregon and Willamette University.
