Testable Question
How does the type of circuit affect the strand of Christmas lights with a burned out bulb?
Independent and Dependent Variables
IV- Parallel Circuit
DV- light
Hypothesis 1
If the Christmas lights are arranged in a parallel circuit, then when one bulb is removed, the other bulbs will light up.
Observations
I noticed that when all the wires were connected to the battery and light bulbs, the light bulbs all lit up.
Independent and Dependent Variables
IV- Parallel Circuit
DV- light
Observations
I noticed that when I took one of the light bulbs out of the parallel circuit, the other lights stayed lit.
Independent and Dependent Variables
IV- Series Circuit
DV- light
Observations
I noticed that when all the wires, light bulbs, and battery were connected correctly, all the bulbs were lit up.
Independent and Dependent Variables
IV- Series Circuit
DV- light
Observations
I noticed that when I removed a bulb from the circuit, the others bulbs went out.
