Central Western Oregon Science Expo (CWOSE)

The Science and Engineering Fair for the Willamette Valley

Sponsored by Willamette University

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 2020 fair?   The next CWOSE will take place on February 29, 2020. The event will start at 8AM and will complete before 6 PM: The detailed 2020 schedule will be posted once ready.

Where is the 2020 fair?   Willamette University will again host CWOSE this year. In the future we plan to alternate locations between the University of Oregon and Willamette University.

How can I participate?   Participation in CWOSE requires advance planning:  students and teachers must understand the rules and fill out paperwork appropriately and on time.  The rules and required documents for middle school and high school projects are different.  Follow the links under the Getting Started tab for specifics.  

How do I register? 

  • Go to the “Online Registration” tab above to register online. 

  • You or your sponsor must also submit the registration fee, which is $5 per participant, payable by check made out to “3-Sigma Institute”.  The registration fee helps offset costs associated with CWOSE activities. Willamette University has assumed all financial responsibility for the Central Western Oregon Science Expo, including meals and facilities. If a student or group considers this fee to be a constraining factor in their participation, a special fund is available to support them. Submit your paperwork and fee as follows:
