The P.A.C.K. project collaborated with Seattle MESA (Math, Engineering, Science Achievement) and NOAA (National Oceanic and Atmospheric Administration) to create a web app (client, server, and data framework) that sparks an interest in STEM for secondary students and helps them navigate pathways to pursue STEM majors and careers. The app features a survey to explore students' interests, a major directory showcasing STEM majors at the University of Washington, a career directory highlighting core skills and knowledge, and an opportunities directory for internships and scholarships. Its goal is to support underrepresented students and foster a diverse STEM workforce.
