Many authors bemoan the fact that Ben Franklin labeled "resinous electricity" as negative, and "vitreous electricity" as positive. By choosing the polarities this way, Franklin forces us to say that electrons carry a charge of negative electricity. Did Franklin make a mistake?
Before you begin your project, consider what you already know about static electricity: At what times do you notice feeling a shock or spark of static electricity?
Think about your hair. What color is it? How are your tresses the same, and different, than someone who has a different color of hair? What happens when you rub a balloon on your head? Write down any notes in your notebook.
Using your notes, make a guess about what will happen to the balloons as you rub them on brown hair, blonde hair, black hair and red hair. Make one guess for each color of hair.
Does hair color affect static electricity? Write down this guesses—called hypotheses—in your notebook. You can use your breath or an air pump to blow them up. Close each balloon with a secure knot. Using the permanent marker, carefully write "Red" on three balloons, "Brown" on three more, "Blonde" on the next three, and "Black" on the last three.
Using the balloon marked "Red" on your red-headed friend, rub the balloon on his or her hair. When the balloon begins to fall, stop the timer. In your notebook, create a table like the one outlined below.
You should have 13 rows and 4 columns. The far left column should have the hair colors listed Red, Brown, Blonde, Black. Then, each column should list the time trials Time 1, Time 2, Time 3. In the column labeled "Red Hair," note how long it took for the first balloon to fall from the wall on your chart under Time 1 for the first time you did it.
Repeat steps 5 and 6 two more times with the red-haired volunteer and the balloons marked "Red". Then, list the second time under Time 2 and the third under Time 3. Write down how long each balloon stayed stuck to the wall after each trial. Repeat steps 5 through 10 with the brown, blonde, and black-haired volunteers.
The times that the balloons stayed on the wall should all be about the same since hair color does not have an affect on the amount of static electricity made by rubbing a balloon on it.
Was your hypothesis right? Everything is made of tiny particles called atoms. These little particles are made of even smaller parts called protons, neutrons, and electrons. But when you slide down the slide at Chuck E.
Cheese, you move those electrons around, creating static electricity. So it was the shift of the electrons of the atoms that made up the hair that caused the force of static electricity, not the color of the hair — which is why your times for each try were all about the same.
Digging Deeper With science, the learning never stops; you can always change an experiment a little bit and get a completely different result!
What would happen if you tried this experiment on a rainy day? Does temperature have an effect on static electricity? What if it were hot outside instead of cold?
Could you change the types of balloons and make a difference in your results? Disclaimer and Safety Precautions Education.

Jul 07, · How to Get Rid of Static in Hair.
When your hair is plagued with static, you might find it impossible to hold and maintain a decent style. Often times the temperature or weather can affect your hair. For example, traveling from a warm climate to a cold climate can cause the hair to have static.
If you’ve dyed your hair, look for a %(2). Nov 15, · Best Answer: Hair color is determined by certain ratios of proteins and other small body chemicals. They have no bearing over the amount of static electricity that a strand of hair, or an entire head of hair, can hold.
You can pick up static electricity from the Status: Resolved. 1._____ diagram that shows the amount that flows from producers to consumer. 2._____ system of overlapping food chains in which the flow of energy branches out in many directions hair color, and skin color.
C. Humans are awesome A. another name for static electricity. The Mysterious Physics of 7 Everyday Things or oozy a foam will be based on the size of its bubbles or the amount of liquid it contains. they can occur when static electricity builds up on.
This creates areas called "hot spots." If you're amount of resistance to the unwinding of the supply rolls so that the film lays flat as it goes into feelthefish.com electricity issues: Static electricity is an issue that may arise as you laminate.
It is impossible to prevent, but can.
