Christmas Light Webquest
Hypothesis 1: If the Christmas lights are arranged in a parallel circuit then when 1 bulb bust (is removed) then the other bulbs will light up.
Observation: I noticed, that when you don't have all wires connected to the battery then the light bulbs will not light up. Also, that when one light bulb is removed then nothing will light up. Then when the wires are connecting only 2 light bulbs our of the three it will light up.
Observation & Hypothesis
