Water Quality Day! GME-UT Staff travel to Delta, Ohio to teach hundreds of elementary students GLOBE water analyses!

GME-UT staff traveled to Delta, Ohio on Friday May 13th, 2022 to help teach hundreds of 5th and 6th graders how to sample and analyze water from the Delta Reservoir using GLOBE hydrosphere protocols! Students also learned how to collect surface temperatures of different surfaces and compare that data. Dr. Kevin Czajkowski demonstrated how to do the analyses, and students split into groups with GME-UT members Sara Mierzwiak, Dr. Yitong Jiang, Olawale Oluwafemi ("Femi"), and Farrokh Namjooyan to collect and analyze their data. Students learned how to throw a bucket into the reservoir and retrieve water, and performed the following water quality analyses: temperature, pH, nitrate, and phosphate. Students also collected air temperature and surface temperature data, and noted the current weather conditions on their data sheets.
