Does soil function as an electrical system?
I believe that soil does act as an electrical system. I believe the moisture in it is probably enough to carry some electric currents. Materials- -60 grams of soil -One 500 mL beaker -Two pieces of 12 gauge, plastic insulated, twisted copper wire about 20 inches long -One 6-volt dry-charge lantern battery with two screw top terminals at the top of the battery Procedures- Place 60 grams of the soil in the 500 mL beaker. Add 500 mL of water to beaker with the soil. Stir the container until the water is completely mixed with the soil. Let the soil materials settle for 10 minutes. On each end of the copper wires, remove the insulation and strip back to expose the bare wire for about 2 inches at the end of the wires. Connect one end of each wire to the terminals of the battery and screw the terminal cap tight to fix the wire to the terminal. Place each of the other ends of the electrical wires in the soil about 2 inches below the top of the water line in the beaker holding the soil. Make su
