Series:Smithsonian Science How webcasts, which are designed to connect natural history science and research to upper-elementary and middle-school students.
This video features Dr. Cara Santelli, a geologist formerly at the National Museum of Natural History. She studies the relationship between minerals and microbes, such as bacteria and fungi. Did you know that microbes are a solution to pollution? Cara works to better understand how microbes can help clean up metal pollutants from old coal mines. Take a journey from Pennsylvania coal mines to an X-ray diffraction laboratory. See how microbes are little machines for mineral transformations. Get to know the microscopic organisms that are essential to the health of our natural environment.
