NEWARK - Some Newark students are drawing some positive attention to their school and looking to solve a world-wide problem.
"Every day I pass the Passaic River on my way to school and I always see how polluted it is," says seventh-grader Gabriel Margaca. 

Gabriel and his classmates at the Oliver Street School in Newark don't like what they see, and are doing something about it.  
Their STEM, or Science, Technology, Engineering and Math class, created a simple and inexpensive solution to the worldwide problem of water pollution. 

"The water pushes the garbage into the filter box and the water will filter out and sift out the garbage and garbage will be stuck in there," Gabriel says.

The project was entered into the national "Samsung Solve for Tomorrow" contest, and they have made it into the top 15.

Their teacher James Intrabartolo is proud of their accomplishment. "I'm very excited for the future after watching these kids work because I know there is a future," he says.

In the process of perfecting their design, students came out to the streets of Newark and tested their prototype on a drain. They say their prototype worked.

"We completed this in a short time period and it actually works and that's the beauty of it," Gabriel says. 

The sixth- through eighth-graders hope that one day their idea will solve a problem not only in Newark, but around the world.  

They are hoping for a top five spot in the contest, which earns their school tens of thousands of dollars in technology.  

But these kids are already winners. "To go this far it makes us proud of what we did and makes the school proud too," Gabriel says.

The public can to vote for finalists in the competition. Voting ends on Thursday.
