__Falling__

__ Time __

Broad Question:
Dose a Bubbles Size Determined its Falling Time?

Specific Question
Will a Large(10-15mm), Medium(5-10mm) or Small(0-5mm) Bubble have a shorter Falling Time?

==//Variables// ==

Independent Variable:

 * Size of Bubble

Dependent Variable:

 * Falling Time (sec)

Variables That Need To Be Controlled:

 * The dropping height
 * Same Bubble Soap
 * Same distance of Camera
 * try for same wind speed

==Hypothesis == I hypothesize that the smallest bubbles will take the longest to hit the ground, followed by the medium bubbles and then the large bubbles.

==<span style="color: #00b1ff; font-family: Verdana,Geneva,sans-serif; font-size: 120%;">Experimental Design == <span style="background-color: transparent; color: #73ff00; font-family: verdana,geneva,sans-serif; font-size: 15px; text-decoration: none; vertical-align: baseline;">I am going to conduct an experiment to inform people about if bubble size determines falling time. Since the height is important and temperature i will conduct this at my house.There will be three people in my experiment. I am going to blow the bubbles while one of my friends takes the picture, another person record the data and directs. <span style="background-color: transparent; color: #73ff00; font-family: Verdana,Geneva,sans-serif; font-size: 15px; text-decoration: none; vertical-align: baseline;">I will blow eighteen bubbles and test them. there well be three different kinds, Large, regular and small. Each size range will have six trials. All the data well be written down, then typed on my x-drive. I will also take pictures and video. Then posted on my wiki and then print and put on my poster.

<span style="color: #00b1ff; font-family: Verdana,Geneva,sans-serif; font-size: 110%;">C onclusion
<span style="background-color: #ffffff; color: #73ff00; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">The purpose of this experiment was to see which size bubble takes the longest to hit the ground. I used three different sized bubble stick holes; a big one, small one and a regular one. The results of my experiment were that the large bubbles (7.05 sec) took the longest, then the small bubbles (5.31sec) and the regular bubbles (4.94sec). Surprisingly the regular bubbles took the least amount of time and the large ones took the most.

<span style="color: #00b1ff; font-family: Verdana,Geneva,sans-serif; font-size: 110%;">Discussion
<span style="background-color: #ffffff; color: #73ff00; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">My Hypothesis was that the smallest bubbles would take the longest to hit the ground, followed by the medium bubbles and then the large bubbles. My results didn’t support my hypothesis. Some patterns and trends were that the larger bubble stayed in the air the longest and didn’t automatically fall. the relationship between the independent variable (the size of the bubble) and the deped variable (the falling time) wasn’t strong. The relationship wasn’t strong because the large bubble didn’t always take the longest to fall. The average showed it took the longest. In all the trials, it wasn’t the longest to fall. I don’t think my test went smoothly. I don’t think it went smoothly because a bunch of bubbles came out at the same time and we didn’t have a real measurement of 5ft. If i could improve my experiment I would be more accurate with height ,take more pictures and try to make one bubble come out. An interesting future study would be ways to make a bubble stay in the air longer. If we figured that out, the size of a bubble wouldn't matter for keeping it in the air.
