Introduction (Testable Question/IV/DV/Hypothesis)
IV: Type of Circuit
DV: Strand of Christmas Lights with burned out bulb
Testable Question: How does the type of circuit affect the strand of Christmas lights with a burned out bulb?
Hypothesis 1: If the Christmas lights are arranged in a parallel circuit then when 1 bulb bursts the other bulbs will light up.
Hypothesis 2: If the Christmas lights are arranged in a series circuit then when 1 bulb bursts the other bulbs won't light up.
Experiment 1 ( Parallel Circuit)
Observations: All bulbs lit up once we put the battery in. The bulbs are bright.
Observation: when we took one bulb in the parallel circuit the other 2 bulbs were still lit up.
Experiment 2 ( series circuit)
Observation: The three bulbs were not as bright with one battery .
Observations: When we removed one bulb in the series circuit the other two bulbs didn't lit up.
The Parallel circuit is the best series to use for Christmas lights. The reason why parallel circuit is better for Christmas lights is because the series circuit lights were less bright than the parallel circuit lights with only one battery. Another reason why the parallel circuit is a better use for Christmas lights is because when 1 bulb was removed 2 bulbs were still on, while in the series circuit when we removed 1 bulb the rest shut off too.
