The University of Cincinnati this month hosted the 75th annual Regional Science Day, a presentation of the Ohio Academy of Science, in the Tangeman University Center.
The academy is a membership-based and volunteer-driven nonprofit organization with a goal to "foster curiosity, discovery and innovation to unite all who value education, science, engineering, technology or their applications to benefit society."

This year's Regional Science Day was made special by the co-presentation of UC's 3D Printers Showcase, an event put on by the 3D Printers Club program, which is sponsored by GCSC and CYF. Celebrating its 10th year, the 3D Printers Club program supports school-based clubs with a 10-week curriculum to reinforce STEM principles by engaging students to design and produce solutions to real-world problems using 3D printers.
The showcase invited clubs from three states to display their learnings and accomplishments from participation in the program. The event also gave students an opportunity to visit booths of other clubs and interact with special visitors. Exhibitors were on hand as well, showcasing future opportunities for students as they continue with 3D printing.
While both annual events provide important ways to advance STEM interest and skills with local youths, Kelley points out that this year's co-presentation of the two in the joint space of the Tangeman University Center presented a noteworthy opportunity. "The combination of the Regional Science Day and 3d Printers Club Showcase brings together two unique groups of students in an effort to foster learning from each other." In total, almost 350 students from 48 schools in 10 regional counties participated in the events, with more than 250 judges, parents and community partners joining them.
