Sentence

The lemon battery is made up of two different metals, copper and zinc. Electric current enters and leaves the battery through these points. These "electrodes" are placed in an "electrolyte," the acid from the lemon, which is a solution that can conduct electricity. A chemical reaction takes place between the acid and metal which causes electrons, which is what energy is made of, to gather toward the negative end of the electrodes and electrons to be lost on the positive side of the electrodes. A current flows from the negative to positive ends in order to push out the excess electrons and for those electrons to take the place of the electrons that were lost on the positive end.
