ElectricityElectricity

Everything in the world is made up of atoms. Each atom has smaller parts in it. One of those parts is called electrons. Electrons can move from atom to atom. When an electron moves to a different atom, it causes another electron to have to move. When electrons move quickly from one atom to another it

is called Electricity!

AtomsAtoms•All physical objects are made up of atoms.

•Inside of atoms are protons, electrons and neutrons.

•Protons are positively charged.

•Electrons are negatively charged.

•Neutrons have a neutral charge. (equal charge)

ChargesCharges• Most of the time objects have an equal amount of protons and electrons. (no charge)

• They are neutral.

• Most of the time objects have an equal amount of protons and electrons. (no charge)

• They are neutral.

ChargesCharges• If an object has more

protons than electrons; it is positively charged. It will be attracted to an object which is negatively charged.

• If an object has more electrons than protons; it is negatively charged. It will be attracted to an object which is positively charged.

• If an object has more protons than electrons; it is positively charged. It will be attracted to an object which is negatively charged.

• If an object has more electrons than protons; it is negatively charged. It will be attracted to an object which is positively charged.

Opposites AttractOpposites Attract

+Objects with opposite charges will attract. So a + and – will come together.

Objects with the same charges will repel (pull apart).A + and + will repel, so will a – and -.

Lightning Lightning • One of the most common forms of static electricity is lightning.

• Negative charges in the clouds are attracted to positive charges on the ground. As the ground takes some of the electrons from the cloud you see the transfer of energy in the form of lightning.

OhOh• Carpet does not hold

onto its electrons very easily so when you rub your rubber shoe soles on the carpet, the rubber collects the electrons. You are then negatively charged and when you touch something else that is positively charged the electrons will jump. This creates a spark.

Static ElectricityStatic Electricity

• Static electricity occurs when electrons jump from one place to another.

• When the object gets near another object with an opposite charge it will either take electrons from the other object or give electrons to it.

• The spark you see is coming from the electrons moving from one object to the other.

Static Electricity and Pollution

Static Electricity and Pollution

• Factories use static electricity to cut down the amount of pollution exiting from their smokestacks.

• They charge the smoke with static electricity. When it passes by any charged piece of metal in the smokestack, most of the smoke clings to the metal. This keeps the pollution from going out into the air.

Current ElectricityCurrent Electricity

• Current electricity is the flow of charged particles through an object, usually a circuit.

• Current electricity is the flow of charged particles through an object, usually a circuit.

The steady flow of electricity is called an electric current. A current will move along a wire or a path called a circuit.

Circuit means to “go around.”

• The holidays are approaching and your dad has asked you to help him put some lights on the outside of the house.

• All day long you worked in the freezing wind to make your house the most bright and beautiful one in the neighborhood.

• The time has come! Dad flips the switch, and OH NO! There at the very top of the house is not just one, but a whole set of lights that are not working.

• Frustrated, but not defeated, dad • climbs the ladder and removes the

light set. He discovers that one little light bulb caused all of the problems.
