Here is my second science project. See what you think. Enjoy!

Purpose: To observe how objects attract each other through static electricity.
Procedure:
1. Blow up two balloons. 
2. Set up a control balloon.
3. Test the control balloon.
4. Test the other balloon by rubbing it on the surfaces required.
Dependent Variable: Attractive force, length of tim balloon sticks.
Independent Variable: Things on left of chart.
Standard Variable: Balloon, Humidity.
Data:



Conclusion: The balloon stuck to most of the objects, but it ultimately depended upon the material we were rubbing it with. The balloon, the hair, the silk, the wool, the cotton, and the dog’s hair are insulators. The transfer of electrons happens more easily between two insulators, meaning an imbalance of charge is likely to occur. This imbalance causes the negative charge on the balloon to be drawn to the positive charge on the other surfaces.
