It all starts with a tiny thing called an atom (say: ah-
tum). Everything in the world is made up of atoms - from
your pencil to your nose. An atom is so small you can't see
it with your eyes - you'd need a special microscope. Think
of atoms as building blocks for all the stuff in the world.
Each tiny atom is made up of even tinier things:
•protons (say: pro-tahnz), which have a positive charge
•electrons (say: ih-lek-trahnz), which have a negative
charge
•neutrons (say: noo-trahns), which have no charge
Most of the time, atoms have the same number of protons and
electrons and the atom charge is neutral (not positive or
negative). Static electricity is created when positive and
negative charges aren't balanced. Protons and neutrons
don't move around much, but electrons love to jump all over
the place!
When an object (or person) has extra electrons, it has a
negative charge. Things with opposite charges are always
attracted to each other, so positive charges seek negative
ones and negative ones seek positives. Whew! Got it?
Beware of Conductors!
If you scuff your feet on your living room rug, you pick up
extra electrons and have a negative charge. Electrons move
more easily through certain materials like metal, which
scientists call conductors. When you touch a doorknob (or
something else made of metal), which has a positive charge
with few electrons, the extra electrons want to jump from
you to the knob.
That tiny shock you feel is a result of the quick movement
of these electrons. You can think of a shock as a river of
millions of electrons flying through the air. Pretty cool,
huh? Static electricity happens more often during the
colder seasons because the air is usually drier, and it's
easier to build up electrons on the skin's surface.
So, the next time you get a little shock from touching a
non electric items or sometimes people, you'll know that
it's just electrons jumping around. Think of it as putting
a little spark in your life!
