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

IV: type of circuit; burned out bulb

DV: how strand of lights is affected

Hypothesis: If the Christmas lights are arranged in a parallel circuit, then when one bursts (is removed) the other bulbs will stay lit up.

Parallel circuit

I observed that all the energy took different paths.

Parallel circuit after bulb burst.

I observed that the other two bulbs still worked, even though one path was cut off.

Series circu

I observed that the energy had only one route to take and the energy ran through every light bulb.

Series Circuit after light bulb bursts.

I observed that the lights stopped working because there was no other path to take.

Data table

To conclude, a parallel Circuit is the best series to use for Christmas lights because when one bulb burst, all the others Stayed lit due to more ways to move Energy.
