I’m a Teacher

Why Should My Students Participate?

Students should participate in science and engineering fairs because it encourages creativity and ingenuity and promotes an inquiry-based approach to learning. Students develop a question, conduct research, analyze data, and share findings. It is an effective way to engage students in applying their knowledge of the scientific method, while further developing skills in areas of literacy, mathematics, and communications. It also promotes positive attitudes towards science and demonstrates to students the relevance of science and research. And if you are still not convinced… it’s also a lot of fun!


All high school students attending private, public, charter, parochial, or home schools in King or Snohomish County are eligible to participate in the fair.  A maximum of 50 projects will be accepted from each school.  Students must first compete in the CSRSEF in order to be eligible for the Washington State Science & Engineering Fair.

Rules and Guidelines

The CSRSEF rules and guidelines are the same as the Intel International Science & Engineering Fair’s (ISEF) standards. Check out the ISEF Rules & Guidelines to learn more.

Science projects should be hypothesis-based and follow the scientific method.   Engineering projects should have engineering goals and produce a product. For more information on how to differentiate between Science Research and Non-Inquiry based Research, check out the Official 2013 CSRSEF Project Guide or Intel’s Student Handbook.

Many class assignments, senior projects, summer research projects, and displays created for other science competitions can be entered into the fair with minimal changes.  Check ouISEF Rules & Guidelines to determine if a project is eligible.

Registration Deadlines

Projects involving human participants, vertebrate animals, potentially hazardous biological agents (ANY microorganisms or viruses), or hazardous chemicals, activities or devices need to be registered online and have submitted paperwork by January 21, 2015.

All other projects need to be submitted by February 11, 2015.

Teacher Resources

Teachers are encouraged to explore tour online Resource Center, particularly the teacher resources contained on our Science Fair Guides Page.

Forms Clinic

Jenn Pang, CSRSEF Director, will be holding an ISEF Forms Clinic on November 12 from 4-5:30 at Bellevue College. If you would like to augment your familiarity with ISEF forms, please join us. Email Jenn at jenn.pang@bellevuecollege.edu.

Get Involved

In addition to encouraging your students to participate in the fair, teachers can get involved in the following ways:

  • Field Trips:  Plan a field trip to the CSRSEF on Saturday, March 7, 2015. Public viewing hours are from 1-3pm.
  • Be a Judge: Volunteering as a judge is a great way to learn more about the science and engineering fair process.

Event Information

The compete fair schedule and driving directions to Bellevue College can be found on our Schedule page.
