Conclusion for static electricity
Answers
Answer:
My experimental question was, "How does rubbing a balloon on different materials at different times of day affect the amount of static electricity in a balloon and, therefore, how long the balloon can stay on a desk?"
The results of my experiment show that rubbing balloons on different materials at different times of day will affect how long the balloon will stick to the desk. For example, the balloon rubbed on the girl's hair stayed on the desk for the longest time, while the balloons rubbed on the boy's hair and the sweater stayed a shorter amount of time at all three times of day. Also, the balloons stayed on the desk for a longer time later in the day.
My hypothesis was that rubbing the balloon on the wool sweater will make the balloon stay on the desk the longest. I also predicted that there would not be a different in the amount of time the balloon stayed on the desk at different times of day.
Both parts of my hypothesis were incorrect because the sweater produced a lower amount of static electricity than was produced by girl's hair. Also, there was a large difference in the amount of time that the balloon stayed on the desk at different times of day.
