Science, technology, engineering, and math (STEM) careers are among the fastest growing and highest paying, yet women are largely underrepresented in these fields, and many girls lack access to STEM opportunities in school. Oregon State University's Open Campus partners with the American Association of University Women to bring an experiential STEM camp, Tech Trek, to middle school girls in rural Oregon with the ultimate goal of increasing the number of women in STEM. Tech Trek serves as a model for intentionally engaging youths to expand access to career opportunities that can be adapted for other Extension programming.
