Aidan Lenski came to the Boulder County Fairgrounds Saturday looking for something.

"I was informed by a friend that there's this really cool convention that goes around from town to town called STEAM Fest," Aidan said.

The 10-year-old is one of more than 5,500 people expected to attend the event designed to encourage kids to explore science, technology, engineering, arts, or mathematics -- STEAM.

"We really wanted to work with kids and families around the idea of making and innovating and iterating and doing things that are hands-on," Anne Fellini, said.

Fellini is the official Master of Maker Merriment for the Maker Bolder nonprofit organization. Maker Bolder puts on this event every year because Fellini says people crave something like this.

"People want to be a part of this," Fellini said. "People are really starting to understand and want to do things with their hands and build and to learn and to explore the sciences."

Chad New drives battle robots as a hobby. 

"I am a huge kid," New said. "I am a 32-year-old going on 14."

He's an electrician by trade and he hopes that when kids watch his robot fight to the death in the glass cage that they are inspired to pursuing a field related to science.

"The trades and working with your hands are an underutilized and under appreciated skill," New said.

Kids like Aidan can run battle robots, make miniature trees, drive a model train, fly a simulated air bomber, race drones.

"You can do all these cool experiments like I made some slime that was made of a chemical reaction," Aidan said.

Among all these activities, Aidan says he found what he was looking for -- passion.

"Science is becoming a really, really big thing nowadays," Aidan said. "By the time I graduate from eighth grade, there's gonna be tons of science jobs."

The Rocky Mountain STEAM Fest continues Sunday at the Boulder County Fairgrounds in Longmont.
