Sarah Nutt and Lydia Crump will exhibit their special brand of ice cream at the Columbus City Schools Exceptional Science Fair to be held from 10 a.m. to noon Friday, Nov. 8, in Beechcroft High School.

Nutt, a junior, and Crump, a senior, are using scientific principles to turn their liquid base – cream, brown sugar and vanilla – into a frozen treat.

The base of the ice cream, which is in a sealed plastic bag, is placed in a container full of ice cubes dashed with salt, which lowers the freezing point of water.

The girls keep a close watch on the bag, shaking the container, hoping their mixture hardens.

It is the 25th anniversary of the Exceptional Science Fair, which will include 100 students, most of whom are from multidisability units at Beechcroft, Centennial, Columbus Alternative, Eastmoor Academy, Independence, Northland, West and Whetstone high schools.

STEM – an acronym for science, technology, engineering and mathematics – students will present their work and members of the National Honor Society will be on hand to provide assistance, said Paul Lasker, a multidisability teacher at Beechcroft, 6100 Beechcroft Road in Columbus, who is organizing the science fair.

Representatives from the Ohio Department of Natural Resources also will attend the fair, Lasker said.

Lasker said it provides students with disabilities an opportunity to show off their science knowledge.

“The main thing, our motto or theme, is ‘ability first,’ ” Lasker said.

The demonstrations, experiments and presentations are based on Ohio science curricula, he said.

“What they do is what they want to do, what they’re interested in,” Lasker said. “The kids provide us with what they’re interested in and we channel them into the proper or appropriate project.”

Anish Tamang, a sophomore at Beechcroft, produced an “energy stick,” a clear plastic tube that is activated by human electricity. When two people join hands and then place their free hands on the device, an LED light pulsates and sounds are generated.

Arbin Jangdami, also a sophomore, invented a robot with crayons attached to the bottom that spins and creates patterns on sheets of paper.

Students are recognized for their work, but no awards are given because the science fair is not competitive, Lasker said.

“It’s more about how the science is coming to the table,” he said. “Every year, we try to mix it up and try to use new stuff.”
