IV: Parallel

DV: Light

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

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

Observation: I noticed that even though one light bulb is missing, the other 2 light bulbs will still light up. All so that, not all wires have to be connected for the lights to shine.

Hypothesis: If the Christmas lights are in a parallel circuit, then when one bulb is removed from the circuit the other lights will still light up.

Observation

Observation: I noticed that if you removed one light bulb none of the lights will light up. If all three light bulbs are connected and arranged in a series circuit then two light bulbs will light up, the third one will never light up.

Conclustion

In conclusion, in a parallel circuit when 1 bulb is removed 2 bulbs light up. In a series circuit, when 1 bulb is removed 0 bulbs will light up. In this matter, the DV in both circuits was light. In a parallel circuit the IV was Parallel. In a series circuit the IV was series. If the christmas lights are arranged in a certan order than all lights will shine, or only some, or even none at all.
