The Maine Department of Education helped host Monday's event to grow interest for science careers in the state.
The free, public event featured hands-on demonstrations, panelists, and some robots moving across the floor of the Maine State House's Hall of Flags.
Computer science teachers and professionals from central and Downeast Maine were also there to show their skills and learn new teaching techniques.
"Jobs that are coming up are going to be based on computers, and need computer science backgrounds," said Allison Braley, a science teacher at Bucksport Middle School. "So it's really important for our students to have that knowledge and be ahead of the curve so they can be successful."
One student from Old Town High School attended with the company he interns for. Called Project Log-In, the company helps people find tech and STEM jobs right here in Maine.
"Technology is developing," said student Matthew Hartt. "There's like too many jobs open and everyone's leaving, so we need people to stay in Maine."
That so-called brain drain is part of why Monday's event was held, to get the next generation of Mainers seeing firsthand what they can do with science.
"Almost every kid out there plays a game nowadays," said Harold Casey, the chair of Eastern Maine Community College's Computer Science Department. "Someone has to write those programs. Someone makes that interactive."
EMCC showcased their holo lens. The technology makes holograms appear for whoever is wearing the glasses, and the viewer can interact and play games with the holograms.
"I like learning new things," said Hartt. "I like being able to do stuff with my hands and see what I can do to better the world."
The closing ceremonies for Computer Science Day featured more networking opportunities for those who want to pursue careers in the computer science field.
