Broad Question
**How can I make a bubble?**

Specific Question
**What effects does temperature have on how long bubbles last?**
 * Variables: Bubble mix, temperature, and time **

Hypothesis
**I think bubbles will last longer when there cold**

Experimental Design
**I will do my experiment at my house or I’ll try to do it at school. I will be doing my experiment on my own. I will need to do three trials. I feel like I will have enough information to make a reliable conclusion. I’m going to record my data in my spreadsheet, then on the computer. I am also going to take pictures of my experiment.**


 * Materials List**
 * 1) **Bubble solution**
 * 2) **Bubble wand**
 * 3) **Refrigerator**
 * 4) **Microwave**
 * 5) **Three containers**
 * 6) **Thermometer**
 * 7) **Measuring cup**
 * 8) **Timer**


 * Detailed Procedure**
 * 1) **Get three of the same jars.**
 * 2) **Pour the same amount of bubble solution in each of the jars.**
 * 3) **Make sure that one of the jars is cold, ones is hot and ones is medium temperature.**
 * 4) **Select a jar and dip the wand so that the bubble solution covers the end of the wand.**
 * 5) **Blow on the end of the wand with the bubble solution to release bubbles. Get a timer and see how long it takes until the last bubble pops.**
 * 6) **Record time in data table.**
 * 7) **Repeat steps with the other jars.**

Background Research
Surface tension is what makes soap bubbles round. The tensions on the inside and outside surfaces. ||  || Temperature can play a role in the surface tension of soapy water. [|Cooling] can make a soap bubble last longer. Cooling a bubble to around -80 Celsius (-112 Fahrenheit) will cause it to solidify. Higher temperatures will cause water to evaporate more rapidly, shortening the life of the bubble. ||  ||

Results
The original purpose of this experiment was to see what bubble will last longer in a different temperature. The results of this experiment were that the colder bubbles lasted the longest. The temperature of the cold bubbles was 16 degree Celsius and lasted a average of 11.18.
