The Hilliard branch of the Columbus Metropolitan Library will be the site of a local activity for the inaugural COSI Science Festival, which begins Wednesday, May 1, and includes four days of activities at the center and beyond.

More than 100 events are scheduled in 17 municipalities.

Hilliard's lone local event is "Be a Scientist with COSI," which is scheduled from 4 to 5 p.m. May 3 at the Hilliard library branch, 4500 Hickory Chase Way.

The free event will provide an opportunity for children to participate in several hands-on experiments that illustrate human anatomy, said Kaitlyn Majewski, manager of the COSI Science Festival.

Majewski said the program would involve measuring against the tallest and shortest humans on earth, looking at organ sizes and talking about "gross things" the human body does.

"The Columbus Metropolitan Library and COSI share the common goal of encouraging young minds to follow their curiosity," said Ben Zenitsky, marketing and communications specialist for the library system.

No registration is required, but the event is limited to 50 participants, according to Majewski.

COSI officials said each community event is designed to make science personal.

No events are planned in which "someone is just going to hand you a flier," said Frederic Bertley, president and CEO of COSI. "These are all hands-on, interactive, participatory events."
