# Christmas Light Webquest

## Information

Testable Question: How does the type of Circuit affect the strand of Christmas lights with a burnt bulb.

Iv: The number of lights Dv: Lights staying on

Hypothesis: The light bulbs will stay on if one is removed.

## Observations

I noticed that the light bulbs still light up bright when three are used.

## Observation

I noticed that even when one bulb is removed they still light up.

## Information

Testable Question: How does the type of Circuit affect the strand of Christmas lights with a burnt bulb.

Iv: The number of lights Dv: Light going out

Hypothesis: The light bulbs will go out if one is removed.

## Observations

I noticed that when they are all hooked in one circuit they are all dim.

## Observations

I noticed that if one bulb is removed they all go out.

## Conclusion

With this experiment I learned that there are many different circuits in lights. One is the Parallel circuit which contains two or more circuits within it. The second is a Series circuit it only has one circuit within it . If one bulb is removed from the parallel circuit the other lights stay on. If you remove a bulb from a series circuit no lights light up. In my experiment I learned about many different circuits.
