This week on SciStarter LIVE! we’ll be joined by Shannon Hardy, a math teacher in Wake County, NC, who engages her class in Sourdough for Science, a citizen science project designed to compare growth rates of microbes in various conditions including… sourdough! "It’s the perfect closed microsystem that ties our kingdoms, a little chemistry, microbiology, math, and biological evolution... that we can eat!" Together, we’ll follow a recipe and protocols and explore creative ways to teach math and science while helping scientists at North Carolina State University learn more about microbes! This event is a part of the Citizen Science Goes Back to School series and is ideal for educators and students in grades 5-8.
