It was a great day to spend in the water, but do you really know what's in the water at Ontario Beach Park? Some local kids now do.

About 50 kids in the "Get Real Science Action Camp" have spent the last week learning about water quality issues at the beach.

They presented their findings to the community Monday. After wading into the water and taking samples, they analyzed bacteria levels, trying to figure out why the beach is often closed.

Their findings weren’t exactly pretty.

"If you do go swimming, don't open your mouth because the bacteria that's in there can make you really sick like E. coli and stuff like that," said Kierra Carter, Freedom School 9th grader.

"When we actually like do activities about it we like learn more and your process of thinking is faster," said JaQuan Ponder, Freedom School 7th grader.

"All of our teaching is set up so we provide opportunities for the students to actually engage in scientific inquiry," said Jared York, UR Warner School of Education.

The camp is put on by the University of Rochester's Warner School of Education.
