Static Electricity

Mini Labs

07-PS2-3: Ask questions about data to determine the factors that affect the
strength of electric and magnetic forces.

07-PS2-5:Conduct an investigation and evaluate the experimental design to
provide evidence that fields exist between objects exerting forces on each other even
though the objects are not in contact.

Background Information

Everything we see is made up of tiny little parts called atoms. The atoms are made of even smaller parts. These are called protons, electrons and neutrons. They are very different from each other in many ways. One way they are different is their "charge."

-Protons have a positive (+) charge.

-Electrons have a negative (-) charge.
-Neutrons have no charge.

Learning Target:Today I am learning about static electricity.

Success Criteria:I can create a model that shows static electricity. .

Usually, atoms have the same number of electrons and protons. Then the atom has no charge;
it is "neutral." But if you rub things together, electrons can move from one atom to another.
Some atoms get extra electrons. They have a negative charge. Other atoms lose electrons.
They have a positive charge. When charges are separated like this, it is called static electricity.

If two things have different charges, they attract, or pull towards each other. If two things have the same charge, they repel, or push away from each other.

When you pull your hat off, it rubs
against your hair (FRICTION) Electrons move from your hat to your hair.

Now each of the hairs has the same negative charge. Things with the same charge repel each other. So the hairs try to move away from each other. The farthest they can get is to stand up and away from all the other hairs.

Multiple Choice

Static electricity can "jump" from the charged object to another object, causing . . .

• static cling (objects sticking together)

• electric discharge (and a shock!)

Multiple Choice

Static electricity is an excess build up of __________.

• protons

Multiple Choice

An object becomes electrically charged when the atoms in the object gain or lose

• electrons

• protons

• neutrons

• all of the above

Multiple Choice

When you rub a balloon up against your shirt, the shirt becomes positively charged. This means that

• more protons were created on the shirt.

• electrons left the shirt and moved to the balloon.

• protons left the balloon and moved to the shirt.

• neutrons left the shirt and moved to the balloon.
