Please help me with my science fair project.

I'm exploring safe ways to remove lead from contaminated soil. One of the techniques I want to use is electrokinetic remediation. From the research I've done, I understand that passing an electric current through the soil should separate lead particles. However, the only diagrams I've been able to find look like this
and I don't understand what's going on there.
So if I want to build something simple to test this out, how do I go about doing so? I get a pot of soil with lead mixed throughout ... and then?
