The slate of COSI Science Festival events in Grove City will include trivia, hands-on activities for youngsters and a chance to gaze at the stars.

A Science Trivia competition will be held from 7 to 9 p.m. Wednesday, May 1, at Massey's Pizza Sports Bar and Grille, 4015 Parkmead Drive.

The event, presented by Excesss Trivia, will include four rounds, each with six categories with five questions for a total of 120 questions. Contestants will compete for prizes including passes to attend COSI After Dark and COSI Science Festival swag. Admission is free.

Elementary and middle school-age children will be able to participate in an evening of hands-on science projects at Grove City's Build, Blast & Grow Science Celebration.

The event will be held from 6:30 to 8:30 p.m. Thursday, May 2, at the Kingston Center, 3226 Kingston Ave. It's free, with no registration necessary.

"It's going to be a fun night of science, with a whole series of stations set up for kids to visit," said Linda Rosine, the Grove City Parks and Recreation Department's environmental supervisor.

"At one station, you'll be able to build and launch a rocket and another activity will involve assembling robots using LEGOs," she said.

Youngsters will learn the basics of being a veterinarian in an activity presented by the Little Medical School-Columbus.

The organization offers multiweek programs throughout the year at the Kingston Center in which children learn about the medical profession by engaging in activities and games using the same instruments used by real doctors and veterinarians, Rosine said.

Other Build, Blast & Grow stations will offer activities relating to plants and the environment, she said.

The evening will include an appearance by Justin Walls, who was named as Grove City's recipient of the COSI STEM Star Award last summer.

Walls was recognized for his self-engineered motorcycles hand-crafted using parts from old vehicles.

He received the award last September at the annual Grove City Arts in the Alley festival.

The presentation was originally scheduled to be made at the city's EcoFest environmental festival in August, but the ceremony was rained out.

The last event in Grove City will be a citywide Star Party from 7 to 10 p.m. May 3 at Scioto Grove Metro Park, 5172 Jackson Pike.

The evening, presented by Columbus and Franklin County Metro Parks, will include glow in the dark archery and stargazing for families, teens and adults.

The star party is free but will be canceled in case of inclement weather.

"It's one of a number of star parties that will be taking place around Franklin County that night as part of the Science Festival," Rosine said. "The Metro Park is a perfect location in Grove City."

The COSI Science Festival is a great way to make science more accessible to youngsters and families throughout central Ohio, she said.

"It brings science to the community for those who haven't been able make it downtown to experience COSI yet," Rosine said. "And, hopefully, the activities will help get kids, especially, excited and interested in science and spur them to take a trip to the museum.

"We're excited as a city to be part of an event that's promoting STEM (Science, Technology, Engineering and Math)," she said.

Grove City was eager to participate when COSI officials first brought up the concept of a community science festival, Mayor Richard "Ike" Stage said.

"It's a progressive and innovative way to encourage interest in science," he said.
