An electric World

• All around us• Nothing will work• No transportation

QuickTime™ and aTIFF (Uncompressed) decompressor

are needed to see this picture.

An Atoms

• An atom is the smallest part of matter

• Protons positive, neutrons no charge,electrons negative

QuickTime™ and aTIFF (Uncompressed) decompressor

are needed to see this picture.

The Charge

• Electrons move to another atom the secound looses electrons

• All moves and makes a charge

• An object gains it is negative, looses positive

Protons, Neutrons, Electrons• Protons are

positive and neutrons have no charge and they are both in the middle

• Electrons are negative and are on the outside

Static Electricity

• Materials can stick to walls because it has a opposite charge

• Can dance around jump• If it has a same charge it pushes away

Example

• Rub a comb against fur or wool

• Electrons from the wool go to the comb

• Bring it close to your hair

• Your hair goes up then

Electric Shock

• Two objects rub each other• It’s then unbalanced• Electrons want to be balanced• Then a shock happens

Current Electricity• Electrons move from an atom to the other• Flows constant• Electrons move slower• Then creates current electricity

Conductors and Insulators

• Conductors let electrons pass easily such as metal

• Insulators do not let electricity pass easily such as rubber

Closed Circuit

• You need batteries, conductors, and power• If it is open it does not work because

electrons have to go through negative to positive

THE LIGHT BULB

• You need a power source, conductor

• Power source- for electrons to lit a light bulb

• Conductor- for electrons to pass

Series Circuit

• A circle• Bad because if one

of every is also

Parallel Circuit

• Not a correct shape• Good because if

one is out others are on

• Each has a equal amount of light

Safety Tips

• Stay away from plugs

• Don’t pull plug with a cord

• Always stay in a house when there is a storm

Magnetism

• A force that attracts certain metals

• Each magnet has a magnetic field

• Each magnet has a north and south pole- the poles are the strongest part

• Opposite poles attract like poles repel

• The earth is the worlds largest magnet

• The earth has two poles north and south

• That’s why a compass works, it is a freely moving magnet

• The south pole of the magnet points to the north pole of the earth

The Giant Magnet

Electromagnets

• Important, it saw the forces

• You have a metal object, wrapped in coil

• Helps compass work, and the earth is a giant magnet

Electromagnet uses

• Makes compasses work

• Helped discover the earth is a magnet

How Electricity is generated

• Copper wires around magnet

• Spins around and causes a movement

• Power lines go to a power plant

Famous Scientists in Electricity

• Bengimen Franklin invented lightning and discovered and protons, neutrons and electrons

• Thomas Eddison - light bulb

• Micheal Farady - generators
