Title: Comparing the effects of depth on the amount of bubbles in club soda.


Problem Statement: How does depth effect the amount of gas (or bubbles) in club soda?


Method and Materials:

Materials:


-13 1 liter bottles of club soda (labels removed)
-1 underwater watch with timer
-1 mesh bag with drawstring
-rope
-1 underwater video camera (from Mr. Harlan)
-underwater writing apparatus (transparency on clipboard, taped with duct tape, and oil pastel)

Method:


1. Set up:

a) Tie rope to mesh bag
b) Fill bag with club soda bottles and lower so that bag is at the middle of the wall underwater.
c) Tie rope (attached to bag) to a diving block or something above water.

2. At the top of the window (5 feet) open one club soda bottle and record time of initial “burst” of bubbles. Repeat 3 more times.

3. Repeat step 2 at the bottom of the window (10 feet), and then at the bottom of the pool (15 feet.)

Discussion (Analytic Essay):

Conclusion: The deeper a bottle of club soda is, the smaller the number of bubbles will be. The shallower a bottle of club soda is, the greater the number of bubbles will be.
