Electrolysis powerpoint and worksheet part 2

A second powerpoint to deal with electroplating. The starter is a trigger powerpoint, i.e. open it up and click on the panel the pupil chooses to answer, it disappears in a catchphrase Ray Walker style. The focus is on electroplating, and when I run this I have a demonstration electrolysis where I first of all copper coat a graphite rod, then swap electrodes to remove the copper, then replace both with copper electrodes (preweighed) and use the power and time to compare to the mass added/lost of the electrodes.
