An estimated 4,500 people attended the 10th annual Onizuka Day of Exploration — a free, family-friendly STEM celebration presented by the Scouting America, Aloha Council — held on April 11 at the University of Hawai‘i–West O‘ahu.
Onizuka Day of Exploration (ODE), which honors the legacy of Hawai‘i-born astronaut Ellison Onizuka, featured more than 100 interactive activities, demonstrations, and exhibits for learners of all ages.
“The energy throughout the day was outstanding,” said ODE Co-Chair Will Hartzell. “The campus was filled with students, families, educators, and community partners engaging in hands-on learning, discovery, and exploration. The event continues to reflect the spirit of Ellison Onizuka — bringing curiosity, innovation, and opportunity together in a way that inspires the next generation.”
Standout highlights and crowd favorites included:
- The presentation by NASA astronaut Mike Fincke, which generated strong interest and excitement across all age groups
- The 45-foot inflatable whale exhibit, offering a unique, walk-through experience that was especially popular with younger attendees
- The Bishop Museum Planetarium, providing immersive space and science experiences throughout the day
- The Cyber Learning Pavilion, where participants explored practical uses of artificial intelligence and digital tools
- The Civil Air Patrol flight simulators, which gave attendees a hands-on introduction to aviation
- The VEX IQ Robotics Scrimmage, showcasing student innovation, teamwork, and competitive robotics in action
Hartzell said in the the days leading up to the event, unstable weather conditions required organizers to make significant adjustments, including relocating booths from the lawn to covered walkways and courtyard areas. The decisions were made with safety and accessibility as top priorities, he noted.
“Thanks to the flexibility and cooperation of our partners, volunteers, and exhibitors, we were able to successfully adapt the layout while maintaining a full and engaging experience for attendees,” Hartzell said. “The ability of the team to pivot quickly ensured the event remained both safe and highly successful.”
This is the fourth consecutive year that the Onizuka Day of Exploration was held at UH West O‘ahu, and Hartzell expressed his gratitude for the university’s role once again.
“We also especially appreciated the support and cooperation of the UH West O‘ahu staff, including Vice Chancellor for Administration David McDonald, and Lynn Reyes and John Murakami from UH West O‘ahu Auxiliary Services, whose partnership helped ensure a smooth and successful event.”
Hartzell said this year’s event was a powerful example of what can happen when a community comes together around a shared purpose.
“Despite weather challenges, the collaboration between UH West O‘ahu; Scouting America, Aloha Council; community organizations; and volunteers made it possible to deliver an inspiring and meaningful experience for thousands of attendees,” he said. “Onizuka Day not only honors Ellison Onizuka’s legacy, but also creates real moments of inspiration that shapes future interests, education paths, and careers.”
