## Question and Hypothesis

How does the circuit effect the lights shown?

IV: parallel circuit DV: number of volts

If the Christmas lights are arranged in a parallel circuit then, when 1 bulb bursts (is removed) the other bulbs will still light up.

## Observations

The parallel circuit worked very well. The lights were very bright. Also, the electrons were moving very fast, and the lights stayed on for a long period of time.

## Observations/Hypothesis

If the Christmas lights are arranged in a series circuit then when 1 bulb bursts (is removed) then the other lights will not light up.

When a bulb was removed, the lights all shut down, and stopped working. They also were not as bright as the parallel circuit.

## Observations

When a bulb was removed from the parallel circuit, the lights all still lit up. The light had no effect on the other bulbs.

## Observations

When the bulb was removed in a series circuit, the other lights stopped working completely.

## Conclusion

In conclusion, the best type of circuit to use for Christmas lights is the parallel circuit. The lights stayed glowing even when the light was removed.
