Static Electricity

Word Cloud

What do you think of when you hear the phrase static electricity?

Electricity runs on atoms….specifically ELECTRONS.

The atom is made up of the following
components:

➔

Protons with a POSITIVE charge
◆p+

➔

Electrons with a NEGATIVE charge
◆E-

➔

Neutrons with a NEUTRAL charge
◆N0

Positive charges ATTRACT negative charges

Positive charges REPEL positive charges

Negative charges REPEL negative charges

Electrons

Protons

Neutrons

Charges

When a surface/item has a charge, it has MORE electrons
(resulting in a negative charge) or FEWER electrons
(resulting in a positive charge.

When a surface/item is neutral, the number of electrons is
EQUAL to the number of protons.

What creates static?

It is the accumulation of EXCESS ELECTRICAL ENERGY on
an object that creates static electricity.

➢

Conservation of charge--charges cannot be CREATED OR
DESTROYED only transferred

➢

When charges transfer from one object to another, this results
in an ELECTRICAL SHOCK!!!

Match

Match the following

• Atom part with a positive charge

• Atom part with a negative charge

• Atom part with a neutral charge

Proton

Electron

Neutral

• Proton

• Electron

• Neutral

How are electrons charged?

1.

CHARGING BY CONDUCTION--Occurs when an object is charged by
TOUCHING it with another object which already has a charge.

How are electrons charged?

2. CHARGING BY FRICTION--when two _________________ objects are rubbed
against each other. One object may pull electrons away from the other, creating one
object with a positive charge and one with a negative charge.

How are electrons charged?

3. CHARGING BY INDUCTION--rearrangement of electrons on a neutral object
by a nearby charged object.

Open Ended

What do all three types of charging methods have in common?

Conductors & Insulators

Conductors: ALLOW ELECTRONS TO
MOVE EASILY

➔

Metals are GOOD conductors

➔

Plastice, wood, rubber glass are
POOR conductors

Insulators: KEEP ELECTRONS FROM
MOVING EASILY.

➔

Plastic, wood, rubber, glass are
GOOD insulators

➔

Metals are POOR insulators

WHY????

On your OUTPUT page, write FIVE
sentences where you give a
SPECIFIC example of a conductor
and an insulator and describe how
those examples are used to
help/protect/prevent something. Be
sure your use is in terms of
ELECTRICITY.
