Testing theories at the science fair

The Springfield Plains Elementary gymnasium was filled with scientists as students presented findings from their experiments during the science fair.
Some students used their siblings or pets as inspiration. Mathias Heisler took a look at how weather effects his sister’s mood.
Others tested to see if their guinea pigs were motivated by sight or sound as they moved through a maze or to see if their pet preferred hay over fruits and vegetables.
Eric Gohl used food as inspiration and hypothesized bread without preservatives molds faster.
“Mold is interesting,” he said about his science project. “I wanted to see what stimulates mold and what stops it.”
He found it took longer than he expected to mold, and it needs moisture.
