Science fair projects run gamut from serious to light-hearted

Corsicana — Just because a science experiment didn’t work out, because your bread didn’t grow mold, or your fingerprints don’t prove inherited whorls, doesn’t mean you didn’t learn.

That was the conclusion drawn by a handful of students at the Drane Science Fair, some of whom came in with “inconclusive” results in their various projects, while others had surprising results showing everything from what food cockroaches prefer for snacks, to whether or not dogs have a dominant paw.

Hailee Ferguson may have had the shortest list of supplies of any of the 69 entrants. Her list consisted of five dogs, 10 treats.

“I have lots of experience with dogs, and I wanted to get to know my dog better,” she explained. She did experiments with the borrowed “test subjects” belonging to family and friends. The work consisted of shaking hands with the dogs, and watching which paw comes first in stepping out. The result? Most dogs are right-pawed.

Whitney Green, on the other hand, couldn’t get the same cooperation from various loaves of bread that refused to grow mold, even though she tried it two different times in two different atmospheres. Thirty-seven days without mold, and the results of her hypothesis that wheat bread would turn green first were “inconclusive.” Green chalked it up to a low temperature in the house and preservatives in the bread.

Lauren Smith used a glucose monitor to show that junk food isn’t good for you, while Sam Guffey showed what kinds of things can inhibit oxidation (browning) of apples.

Devan Lindsey’s project was to determine which kind of baseball bat —aluminum, wood or composite — would hit a ball farthest. It was tough work, hitting balls with a friend until he’d hit three balls with each of the bats, but he made the sacrifice for  science.

“I thought it would be funner and easier,” Lindsey said honestly.

Ashlee Wafer’s mom hates cockroaches, but Ashlee didn’t cringe from her project to prove that cockroaches prefer junk food to health food. Except, the 15 hissing Madagascar cockroaches who were provided by the science department for the project preferred lettuce over potato chips.

“I’ve always been interested in bugs,” Ashlee said, pointing to a photo of a giant bug on a finger. “That’s me, holding one of them.”

The awards ceremony for the Drane Intermediate School Science Fair will be at 6 p.m. Thursday, at which point the parents will have a chance to view all the projects. The top students in the fair will travel to Waco for regional competition, and any students who succeed there will go onto state competition in San Antonio.

  • 3-26-14 Expo Commercial heifers.jpg Curl wins first leg of Commercial Heifers

    Caleb Curl, 13, of Frost FFA, won grand champion of the commercial heifer show, the first leg of the commercial heifer overall prizes. Unlike a lot of the other animal categories, commercial heifers aren't show-things with smooth coats and stardust on their hooves. They're straight out of the pasture, a bit muddy and certainly not the lady-like, pampered creatures that will be led around the ring in the registered heifer show.

  • 11-21-13 Annie.jpg ‘Annie Get Your Gun’ through Sunday at the Palace

    It’s the big musical, the one that makes me think of ‘cast of thousands,’ or in our case, dozens at least, and it’s here only for a few short days. ‘Annie Get Your Gun,’ is Irving Berlin’s candy box treasure of a play about Annie Oakley, the sharpshooter in love with a showman.
    It’s presented by the Warehouse Living Arts Center but because of its size is on stage at the Palace Theatre. Shows will be at 7:30 p.m. tonight, Friday and Saturday, with a 2 p.m. Sunday matinee.
