Westerville is playing host to a variety of events as a part of the COSI Science Festival running from Wednesday, May 1, through May 4.

Jenny Hill, communications director for Otterbein University, said the university will host its own events and also will have tables at COSI during the festival.

Hill said the university's event Wednesday, May 1, will allow children and families of all ages to explore Science, Technology, Engineering, Arts and Math careers with virtual-reality equipment and 3D printing and scanning demonstrations. She said the event will have a make-and-take corner, a demonstration on laser engraving and solar ovens.

Hill said the university's tables at COSI will focus on "The Grossology of Things." Two tables will have different shapes of animal scat; two more will have "the smell of things" in vials. Staffers will also be dissecting eyeballs every 15 minutes, she said.

Neither event requires registration, she said.

Frederic Bertley, CEO and president of COSI, said the organization "cannot put on this festival of four days of events ...by ourselves."

"We don't have the staff or the capacity. The key to make this work is through partnerships. They've been the bread and butter. That includes the 12 city mayors that have agreed to work with us," he said.

"Putting this on at this scale has been possible through the partnerships we've been able to set up, and those partnerships helped us pick the sites,"

Support has come from organizations and municipalities who "speak the STEM language," he said. "These are all hands-on, interactive, participatory events."
