## Testable Question

How does the type of circuit affect the lights?

IV: Type of Circuit

DV: Lights

## Test 1

Hypothesis: If the Christmas lights are arranged in a parallel circuit, then when one light bulb is burst the bulbs light up.

IV: parallel circuit

DV: lights

## Observations 1

I notice that when i removed one light bulb, the other two light bulbs were still light up. As i removed the other light bulb, the last light bulb was still light up.

## Test 2

Hypothesis: If the Christmas lights are arranged in a series circuit, then when one bulb burst the bulbs won't light up.

IV: Series circuit

DV: lights

## Observations 2

I noticed that when I burst one light bulb, the other light bulbs didn't light up. When I also burst another light bulb, it still didn't light up.

## Conclusion

A parallel circuit is the best series to use for Christmas lights because when I removed one light bulb, the other light bulbs weren't affected and were still light up.
