SEDGWICK – Students in the fourth through eighth grades have been working on science projects for the annual Science fair.

Science teacher Ed Kingsley said, “Some of the students had been working for months, others not so long.”

Students could work alone or in pairs, and most chose the two-man approach. “Slime was big this year,” said Principal Pat Breckunitch.

Each student or team of students had to identify a question, come up with factors and develop a hypothesis on what their project would reveal.

Some of the projects were what liquid makes plants grow taller, which toothpaste removes stains better, what brand of bottled water has the lowest PH, and which kind of carbonated soda makes a bigger explosion with Mentos mints.

The students had to set up a presentation board, showing their experiment and results. The projects were on display for the public, Monday evening, May 8.

Fourth grader Colton Longstaff explained that he and partner Micah Hansen tried four different types of toothpaste on spaghetti sauce stains. The toothpastes tested were Crest for  kids, Crest Pro-health Advanced, Colgate Enamel Health, and Colgate kids.

The boys put spaghetti sauce stains on a t-shirt, let it dry, then scrubbed with a toothbrush and toothpaste to see which brand and type were more effective. Longstaff said he and Hansen were surprised with the results. “We thought it would be the Crest Pro-Health, but the Crest Kids did the best job,” Longstaff said.
