How smart are horses?
VAIL What is the IQ of a horse? Are eyewitnesses reliable? Does salt affect the freezing point of water? And, which kind of milk skim, 2 percent or whole spoils the quickest? These are a few of the questions Vail Mountain School seventh and eighth graders investigated for this years science fair, which was held Monday. Ever wonder exactly how healthy those energy drinks are for you? By testing the pH levels of several energy drinks, seventh grader Emily Domke discovered that Amp and Propel are extremely acidic while Gatorade and Vitamin Water carried the most neutral pH. Seventh grader Elizabeth Graves experiment to determine the IQ of horses led her to hypothesize that, They’re not too smart.
She explained that working with a subject that was easily distracted and uneager to focus was not easy, but it was still fun being around them.Eighth grader Rhiannon Spillane answered the age-old question, Are Blondes Really That Dumb? Her experiment tested the memory capacity of 12 blondes and 12 brunettes through a memory game. Being a blonde myself, I really wanted to prove that blondes arent dumb, and I did, Spillane said.The results of her testing showed that blondes remembered an average of 5.7 items in the memory game; brunettes remembered an average of 5.4 items. Spillane admits that this hypothesis is only based on one group of Vail Mountain School students in grades 7 and 8, and results could vary in another experiment using different students in different grades. Overall, though, she says shes happy with her results.
Eighth grader Amelia Ortiz presents Emotions in Motion which won most original experiment to Gore Range Natural Science Schools Carol Busch.
Seventh grader Kelli Lindsay tested the effects of Vitamin Water on the Dracaena plant, hoping to prove that the Vitamin Water-fed plants would grow more quickly. She discovered that plants fed with regular water grow the tallest.
Seventh grader Barrett Buscher’s science fair project asks, Do cell phones affect reaction time?His project won best overall.
Seventh grader Addison Baker demonstrated that shorter bridges are stronger.
