Questions:

What kind of circuit will produce electrons flow in your fruit/vegetable  cell? 

A series circuit.

If your bulb doesn’t glow, how can you find out if electrons are flowing?

You can see electrons are flowing if your voltmeter moves

If your bulb doesn’t glow, why not?

There is not enough power and electrons aren’t glowing

How can we modify out experiment to improve our results?

Make sure your cords are correctly plugged

What is causing electrons to flow in this experiment?
