  • On Oct. 22 and 24, the seventh and eighth grade STEM (Science, Technology, Engineer, and Mathematics) students at Sleepy Eye Public School engaged in a hands-on exploration with Minnesota Valley Testing Lab (MVTL) in New Ulm.
     
    MVTL chemists demonstrated to students how to test for chlorine in water, how to dissect the different dyes used on M&Ms candy and how to measure the density of feed.
     
    Students also took swab samples of different areas of the school testing for bacteria.
     
    The MVTL chemists brought the samples back to their labs for growing to see which items had the most colony forming units of bacteria. Out of 16 swabs taken throughout the school, the bathroom door handle in the high school had the highest CFU while the lowest was the high school entry way railing.
