An easy way is to use sulfuric acid solution in a beaker. Take your piece of copper and cut it into two electrodes. Attach your electrodes to wires and connect the wires to a battery. Place the electrodes in the beaker. Depending on how strong your battery is, the electrodes will gradually dissolve and the solution turns blue. After a while, you can boil off the water and collect the copper sulfate crystals.
