Who knew some pieces of copper and some saltwater would be enough to generate electricity? The fifth of 14 lessons in the Cost Effective Solar Cells unit challenges scholars to create a solar cell. They take two copper sheets, use a hot plate to oxidize the copper, then place the sheets in saltwater. After connecting the sheets with a multimeter, they test out their devices both indoors and outdoors.
