The latest news about the Fair, projects, awards and opportunities.

Science Fairs provide an opportunity for students, 1st through 12th grades, who are interested in science and technology to pursue their personal areas of interest and to display their research as a presentation in a public competitive forum.  The Washington State Science and Engineering Fair works to create enthusiasm in science and technology while encouraging project-based inquiry.  The WSSEF provides your students the chance to compete for college scholarships, awards and other exciting prizes.

Hearing the students talk about their projects, their goals and why they come to the WSSEF justifies the immense time, money, effort and countless hours it takes to put on the Fair.  Job VERY well done everyone!

View the final product from the two days of filming at the Washington State Science & Engineering Fair (WSSEF).  The television show, Inside Bremerton, is aired on the Bremerton Kitsap [County] Access Television (BKAT) stations at various run times.  While there are a number of other WSSEF shows and snip-its in their archives, this is by far the best rendition of what the Fair is and captures it’s essence.
