Electrolytes dissolve by dissociation. That is when the molecules of a substance break down into charged particles called ions. An ion with a negative charge is called an anion because it is drawn through the solution to the positive charge on the anode. A particle with a positive charge is called a cation. It moves through the solution to the cathode. Water has its solvent properties because it is polar. The molecule has charged ends (+ and -). These charged ends react with charges on other polar substances to dissolve them. They do so by taking hydrogen atoms from the substance to form hydrogen ions.

Talking

umm...how long you have for this experiment, cause you can probably do the weathering of rocks in water, or you can do it on electrolysis, i strongly suggest electrolysis cause my friend she did it and it was good and sucessful but you need to think fo something you can test with this like trying electrolysis on water, seltzer, and lets say vitamin wtaer and see what happens...
