For the second year in a row, a team from Oceanside High School West has won the state title in a science, technology, engineering and math competition called eCybermission

The ninth-grade team members researched, designed, and constructed an experiment to propose a solution to a real problem to benefit the community.

Team members are: leader Emmanuel Tung, Nathan Hersom, Hunter Dinsmore, and Ryan Lawrence. They each received a $1,000 in U.S. Savings Bonds per member per year.

eCybermission is a web-based Science, Technology, Engineering and Mathematics competition for sixth- through ninth-grade teams.

Oceanside West's eCybermission team chose to investigate the problem of polluted runoff from Maine paper mills getting into lakes and rivers.

"We designed and constructed a scale model of a device that would purify the runoff while generating hydro-energy simultaneously. First, our attempt to visit an active paper mill was unsuccessful, so we conducted extensive background research, including government resources. After inquiring about the context-relevant pollutants and different hydro-electric generators, we came up with the design for our hydro-electric motor to generate as much energy as possible and found the best way to filter out as much pollutants as we could in as little time as possible," students explained in a news release.

"Our experimental process began with constructing our scale filtration system/hydro-energy generator to start testing. Once constructed, we poured water with dirt (to represent pollutants) down the prototype and measured how much power was generated as well as how much dirt was filtered from the water. We repeated this test several times to perfect our design, and we collected/analyzed this data. Our small scale results looked very promising, but this design may have to be further tested to be ready for commercial use. The next step in this process would be to test/optimize a full-scale design under true conditions, and after positive results, implement it in Maine paper mills."

Last year's winning project was related to ocean acidification and the shellfish industry.
