Students tackle potholes and win big in a national competition

Students atSt. Kevin's High Schoolin St. John's looked no further than the common pothole to find inspiration for a national competition, and emerged triumphant.

"We had a couple of ideassmoking in cars, crime, theft [and]in the end we decided to go with pavement, said teacher MikeSchulz, describing how students at the school came to pick their mission in Solve for Tomorrow TechnologyContest.

Shulz said the mission was to examine potholes, including "what causes potholes, is there anything we can do to try and at least prevent them a little bit."

The nationalchallenge asks schoolsacross Canada to come up with solutions forproblems intheircommunitiesusing science, technology, engineering and math.

A group of Grade 9French immersion students from the school were the only applicants from Newfoundland and Labrador to makeit into the third and final round of thecontest.

Hands on learning

LucasChaulk,one studentinvolved in the experiments,said the processinvolved a series of tests that involved hands-on learning. They also completed aYouTubevideo of their project.

"We had samples from one of [a contractor]who does the pavement. We had plastic containers and we would put them in there and see if the water would stay in or fall out," he told CBC'sSt. John's Morning Show.

"Then after that, webrought it to[the College of the North Atlantic]and started compacting the pavement to see which one was the strongest."

Teacher Caitlin O'Brien found the project exciting.

"This group was really great to work with, they were really energetic," she said.

"The kids learned actually thatthe makeup of pavement is ... liquid asphalt, sand and basically the percentage of that found in the asphalt is going to affect its strength and durability."

In the end, the experimentconcluded that drainage on pavement is very important andthe less water goingthrough the asphalt, the better, but theshape of the rock used in the pavement made a big difference.

"We could differentiate, but in my opinion I think it should be more square instead of more like kind of a circle," said Chaulk.

If the students were to take the shape problem any further, saidSchulz, itwould mean taking the project out of the lab and into the real world, but that would also take more extensive research andmany months to complete.

Proud achievement

St. Kevin's hasreceived $20,000 worth ofSamsungtechnology, which consists of 40Samsungtablets, saidSchulz.

The school isnow one of 11 finalists from across the countryin the running for two grand prizesof $50,000 worth ofSamsungtechnology.

The entire school is thrilled withthe students'win and are rooting for them in the next round.

"We're so happy for the kids, that they came this far, thatthey got this experience and got to see basically that what they do in the classroom can havean effect on a real world problem," said O'Brien.

Chaulk said coming this far has been a great feeling and experience for himself and the others involved.

"I think they all feel like pretty excited to get this far ... overall it's going to be worth a whole lot of technology and hopefully no more books."

The students are looking for help from the communityto win the next round of competition.

While one of the final prizes will be decided by Samsung, the other is decided by an online vote.

Voting ends on April 18.
