Bubbles

=Define the Problem=

How long does a typical bubble last before it pops?

=Research the Topic=

Bubbles stick together, a.k.a. "budding" Bubbles are made out of soap and water Bubbles disappear in the air and when they hit something

=Make Observations= Bubble Videos

The bubbles are spherical, shiny, soapy and they have clear reflections.

=Experiment=

Materials: -Bubbles -Stopwatch
 * __Materials and Method__**

Method: 1. Start the timer when the bubbles emerge. 2. Blow horizontily. 3. Choose one medium sized bubble. 4. Stop timer when bubble pops in air or on the ground. 5. Repeat for more times (5 times total). 6. Average Data.

=Analyze Data= This table shows each trial of a bubble for period 3. The average of period 3's data is 9. 60 seconds and the class median was 10.06 seconds.
 * Trial || Time (seconds) ||
 * 1 || 5.63 ||
 * 2 || 7.88 ||
 * 3 || 10.87 ||
 * 4 || 18.16 ||
 * 5 || 5.44 ||

This table shows each trial of a bubble for period 4.
 * Trial || Time (seconds) ||
 * 1 || 7.16 ||
 * 2 || 9.97 ||
 * 3 || 5.5 ||
 * 4 || 8.15 ||
 * 5 || 6.17 ||

The average of period 4's data is 7.5 seconds and the class median was 7.86 seconds.

=Draw Conclusions= Period 3 Results: The average bubble lasts 10.6 seconds. Period 4 Results: The average bubble lasts 7.6 seconds.

As you can see, our two classes have different results, due to variables that can't easily be controlled. These varibles include the size of the bubble, air conditioning, wind, and the environment in which the bubble was blown. If these variables could have been controlled, our two classes would have more accurate results, and therefore have more simular results.
