Join us for this hands-on workshop right here at the CSI laboratory (95 Brown Rd, Ithaca NY 14850) to learn about ways that water can be polluted and cleaned. Kids will work in teams to build water filters out of natural materials. Then, they’ll test how well these filters work on water they “pollute” (i.e. using soil, road salt, etc.). Attendees will get a chance to run basic tests themselves before seeing how CSI’s professional scientists look for bacteria in water (spoilers: the test makes it GLOW). Kids will get a postcard by mail a few days after with results on how much bacteria remains after running water through their filter!
