Broad Question
Does the surface tension change depending on the temperature of the water?

Specific Question
Will 40, 65 or 80 degree Fahrenheit have more surface tension?

Hypothesis
I hypothesize that the 80 degree water will have more surface tension, followed by 65 degree then 40 degree.

**Experimental Design**
I will conduct this experiment either at home or at my aunts house. I will get all of my materials. Heat and cool the water to the temperatures that are needed. I will set out a few pennies. Then I will see how many drops of each temperature of water I can get on each penny. I will record the data directly on to my laptop.

Materials List
Penny Thermometer Dropper Water Cups Computer

Detailed Procedure
I will gather my materials and then
