At one can see a demonstration on making and using potato batteries to light an LED. The video does use a fair amount of vocabulary on basic electricity, however, it does show well how to use meters and how to connect batteries in parallel and in series.

An interesting activity is to show how common battery cells can be linked together inside of a larger battery container to make a battery with more voltage.

A tour to a battery factory would be a nice follow-up. It would help show real world applications for the lessons.
