## Testable Question

What would happen if a light bulb is removed from a strand of Christmas lights?

## IV and DV

IV- the number of bulbs.

DV-wither the light shows or not.

## Hypotisest 1

If the one bulb is removed then the other lights will not shine.

## Observation

I notice that the bulbs run along the same wire to make a complete circuit.

## Observation

I noticed that when a light bulb are attached along the same wire and when the connection is broken then the lights don't shine.

## Hypothesis 2

If the light bulb is removed from the strand of lights then the strand only has one light not lit.

## Observation

I noticed that the bulbs are connected by there own wires.

## Observation

All the other lights are connected on their own circuit so when one falls it doesn't take the rest with it.

## Conclusion

In conclusion, both hypotheses were correct the parallel circuit light with zero bulbs removed and didn't with one removed on the other hand the series circuit shined both times.
