# Review Energy-6

1. ### The balloon stuck because I don't have enough hair.

No. While much of my hair is gone, I still have enough to do this experiment.
2. ### The balloon stuck because the balloon had the same charge as my hair.

No. Two things with the same electrostatic charge will repel, pushing apart.
3. ### The balloon stuck because the balloon had a different charge from my hair.

Yes. When I rubbed the balloon against my hair, electrons moved from my hair to the balloon. The extra electrons gave the balloon a negative charge, and the missing electrons left my hair with a positive charge. Opposite charges attract, so the balloon stuck to my hair.
4. ### The balloon stuck because my hair was magnetized.

No. Rubbing a balloon against something does not magnetize it. Even if it was magnetized, a magnet would not attract the rubber balloon.

SC.5.P.10.3 Investigate and explain that an electrically-charged object can attract an uncharged object and can either attract or repel another charged object without any contact between the objects.
