Incredible Science Fun Learning Ideas:

  • The copper plates act like the positive electrodes of a battery. They
    are plated with a metal which is less reactive than zinc. When
    the copper plates and zinc plates are inserted into the lemon,
    a chemical reaction takes place. Electrons (extremely small
    particles with negative charge) move from the zinc plates to
    the copper plates to form a current, thus activating the
    LCD watch. The lemon juice helps to conduct electricity.
    You can replace the lemon with a potato, a grapefruit or
    use soft drinks and see what effect this has.
