About UIUC Engineers Without Borders

Engineers Without Borders at the University of Illinois Urbana Champaign is a student run nonprofit organization dedicated to partnering with underserved communities to design and implement sustainable engineering solutions. Our chapter works on long term, community driven projects that improve access to essential resources such as clean water, sanitation, transportation, and infrastructure. Our members come from a wide range of engineering disciplines and backgrounds, and we emphasize technical excellence, cultural understanding, and sustainable design. Through hands on project work, collaboration with international partners, and local outreach, we strive to develop thoughtful engineers and leaders who are committed to creating lasting, positive global impact.

About the World STEM League

UIUC EWB Junior Science Competition is part of the World STEM League. In the League, students compete across multiple competitions throughout the League Year, allowing them to:

  • practice repeatedly
  • track their improvement over time
  • collaborate with teammates across competitions

This creates a cycle of growth: compete, learn, refine, and improve.

About the World STEM League

Fostering Curiosity and Real-World STEM Learning

The UIUC EWB Junior Science Competition is designed as an enriching introduction to STEM that nurtures curiosity, reinforces classroom learning, and encourages students to think beyond the textbook.

The experience begins with a grade-level-appropriate online challenge aligned with core math and science concepts. Students then engage in developing solutions to real-world problems through drawing, building, and creative thinking, before sharing their ideas through a poster for the lower primary category and simple presentations for the upper primary category.

Each stage is intentionally structured to build confidence, develop problem-solving skills, and foster interest and curiosity in STEM.
