## Testable Question

How does the circuit patterns effect the brightness and strength in Christmas light signals to one to the other?

## Independent Variable and Dependent Variable

The Independent variable are the Christmas lights circuit pattern.

The dependent variable is the Christmas lights brightness.

## Hypothesis

If the Christmas lights are arranged in a parallel circuit when a bulb burst the other bulbs continue to light up.

## Content

The parallel circuit creates more light and is more efficient.

## Observations

When one bulb was removed the entire circuit was uneffected.

## Hypothesis 2

If the Christmas lights are arranged in a series circuit then when a bulb burst the other bulbs turn off completely.

## Observation

The circuit produces less energy than a parallel circuit.

## Observations

removing one bulb turned the entire circuit off.

## Conclusion

A parallel circuit is the best series to use for Christmas lights because the parallel circuit produces more light than a series circuit and if a light burns out then the parallel circuit wont burn out but a series circuit would turn of completely.
