In a neighborhood in Philadelphia, members of the CSSM, in collaboration with our partners at The Franklin Institute, participated in a community outreach event, Soil Shop, to help people learn about the hazards of lead in soil, as well as how to mitigate it. Building on the experiment based on separations developed in the center, community members learned about soil as a mixture of nutrients and potential hazards, such as lead. Using size, magnetism, and solubility, attendees got to see mechanisms for how some things can be separated and some, like lead, cannot.  Special thanks to Max Furigay, Jeff McNeill, and Alex Weberg who helped present the experiment to the Franklin Institute’s ambassadors!
