1. What is Static Electricity?
You walk across the rug, and reach for a doornob…ZAP! You get a shock
Come inside from the cold pull off your hat…BOING! All your hair stands on end. Why does this only happen in the winter?
STATIC ELECTRICITY

2. Cartoon of the Day

3. The result of a buildup or stealing of electrons. (a negative charge)
Static Electricity
The result of a buildup or stealing of electrons.
(a negative charge)

4. First a little about the nature of Matter
Imagine dividing a pure gold ring in half
Keep one half and give the other away
Divide your half again and give half away
Keep doing this and eventually you wouldn’t be able to divide it anymore
GOLD ATOM

5. Parts of an Atom In the center of each atom is a NUCLEUS
Contains 2 particles
PROTONS
NEUTRONS
Orbiting around the nucleus are smaller particles called ELECTRONS

6. Atom Useful to think of the Atom as a solar system
The Nucleus is like the sun
The Electrons are like planets orbiting the sun
Just like the Sun the Nucleus is large compared to the orbiting electrons

7. Electrical Charges
Protons, Electrons, Neutrons each have their own properties
Electrons have a negative charge (-)
Protons have a positive charge (+)
Neutrons have no charge or are neutral
Protons have a charge that is exactly opposite and equal to that of Electrons

8. Electrons can Move!
Protons and Neutrons are held together very tightly in the Nucleus
Some of the OUTER Electrons in atoms can move from one atom to the other
Normally Atoms have no charge

9. Electrons can Move!
When an Atom receives extra electrons it GAINS MORE NEGATIVE CHARGES
Thus becomes negative (-)
When an Atom loses electrons it GAINS MORE POSITIVE CHARGES
Thus becomes Positive (+)

10. Charged particles exist in atoms.
Electrons are responsible
for negative charge;
protons for positive charge;
neutrons have no charge.
Small amounts of ordinary matter contain
incredible amounts of subatomic particles!

11. material through which charges will not easily move
Insulators
Some materials hold very tightly to their electrons
Electrons don’t move very well through these materials = Insulators

12. material that allows charges to move about easily
Conductors
Some materials have loosely held electrons
Electrons move very well through these materials = Conductors
Conductor
material that allows charges to move about easily

14. Opposites Attract
Positive and Negative Charges behave in interesting ways!
Two things with opposite (positive and negative) charges will attract each other
Two thing with similar charge (2 positive, or 2 negative) will push each other away

15. Charged objects Charged objects will also attract neutral objects
Eg: rubbing a balloon in your hair creates a charge on the balloon
It will then be attracted to a neutral wall

16. So on a bad hair day all the hair on your head has the same charge and they all repel each other.
