Christmas lights WebQuest

How does the type of circuit affect the strand of Christmas lights with a burned out light bulb?

(IV) type of circuit (DV) burned out bulb

If the Christmas lights are arranged in a parallel circuit then when 1 bulb bursts the other bulb will not light up.

When we have 3 bulbs they all light up 

I noticed when I took one bulb out the rest was working besides the place we took the bulb from.

If the Christmas lights are arranged in a parallel circuit then when 1 bulb bursts the other bulbs will not light up. 

When I had all bulbs I noticed that all of the lights lit up.

I noticed when I take a bulb out none of it lights up.

I noticed that on the parallel circuit when I took one bulb out 2 lit up and on the series circuit when I took a bulb out none lit up.
