The Science Fair at Great Expectations School on Thursday, April 25 had 36 displays. Eli’s was one of the most popular, with people popping their head inside a black box to see how crystals react to light.
Great Expectations School in Grand Marais opened it doors to parents, grandparents and friends on Thursday, April 25 for the annual Science Fair. Visitors enjoyed 36 displays by students from Great Expectations and Oshki Ogimaag of Grand Portage.
Visitors were treated to a wide range of scientific results, presented in a myriad of ways. Students used audio and video presentations, elaborate drawings and interesting hands-on activities to present their findings.
There was a study on the best liquid for spider plants—water, Sprite or vinegar? A video softly playing I Will Survive showed the results. Viewers learned that a spider plant will not survive in vinegar!
There were reports on the oxidization of copper, on mummification, on the absorption of medicine, on water pressure, on things that glow in the dark and things that fly. Some students used their pets for their experiments. There was a study of whether a dog or cat can be right- or left-pawed, as a human is right- or left-handed. And a student asked—which will sink deeper in the snow bank, a cat or a rabbit?
One science experiment, conducted by two young men named Michael, was to determine what type of Coca-Cola reacts stronger to the addition of Mentos candy—regular or diet. The result? Diet Coke and Mentos made the bigger eruption.
Everyone had a great time reviewing the different results and it seemed that everyone learned a lot.
Annie and Jorden studied the peregrine falcon, the fastest animal on the planet, and learned that it reaches up to 200 miles per hour. After their experiment, the girls concluded that the shape of the peregrine falcon’s wing plays a role in how fast it goes.
Lynden debunked the Internet urban myth about different combinations that will make Mountain Dew glow. Lynden’s conclusion? If you want a long-lasting glowing item, just use a cyalume light stick.
Ellen researched what types of liquids cause copper to tarnish (oxidize) the most. Ellen found that a penny soaked in baking soda water turned the blackest and faded the most.
