Static Electricity Experiment

We had fun today learning about static electricity.

Question: What happens when you rub a balloon on your hair?

Hypothesis: Hair will stand up after you rub it with a balloon.

Equipment: You will need a balloon and your hair.

Method: First we blew a balloon up. Next we rubbed it on someone’s hair. We rubbed it for 10 or more seconds.

Results: The hair stood up and to the balloon.

Conclusion: When we rubbed the balloon on someone’s hair the positive particles rubbed off our hair onto the balloon. The negative particles in  the hair wanted to be together with the positive particles in the balloon.

Static Electricity Experiment

Question: What happens when a balloon is rubbed against hair?

Hypothesis:Hair will stand up after we rub it with a balloon.

Equipment: Balloon, hair.

Method: First we blew a balloon up. Next we rubbed the balloon on somebody’s hair. We rubbed it for 10 seconds or more.

Results:The hair easily stood up so it is true that when you rub a balloon on your hair your hair floats.

Conclusion: When you rub a balloon on somebody’s hair the hair stands up.

The reason is-  because there is more positive than negative particles in the balloon. Positive and negative particles love each other so that is why your hair had floated up.
