Minnesota Sea Grant awarded three certificates at the Northeast Minnesota Regional Science Fair at UMD on February 10. The certificates were for projects relating to Minnesota Sea Grant’s mission of supporting science that will help keep Lake Superior and other Minnesota lakes healthy.

The winning projects were:
“Are E. coli Concentrations Higher in Heavily Used Areas than Less Used Areas of Tischer Creek? Do E. coli Concentrations Change with Rain or Snow Events?” by an eighth grader at Holy Rosary School.
“Can I Simulate a Hurricane and Predict the Damage?” by a ninth grader from Hinckley-Finlayson School.
“What Effect do Different Oil Slick Removal Techniques Have on Daphnia magna?” by two ninth graders from Cloquet High School.
