1. Electricity By Lior Gliksman

2. An Electric World • Lights are electricity • There would be no computers • There would be no TV • There would be no machines

3. Atoms • The smallest part of matter • Made up of: neutrons electrons and protons • Neutrons-no charge • Electrons- negative charge • Protons- positive charge

4. Protons, Neutrons, and Electrons • Neutrons and Protons are in the middle of the atom • Electrons are in the side of an atom • A atom has no charge because it has both Protons and Electrons

5. The Charge • Electrons are the secret to electricity • If an object loses electrons it has a positive charge • When 2 objects are rubbed together electrons can move to the other object • When a electron moves to a different object electricity happens • If a object gangs electrons it has a negative charge

6. Static Electricity • When atoms have the same charge they repel or move away • When atoms have a different charge they attract

7. Example • Fill a balloon with air and tie it • Rub it on your clothes • The balloon will pick extra electrons • Put the balloon on the wall and it sticks! • This happens because the balloon has a negative charge • Opposites attract and do the balloon is staying on the wall

8. Electric shocks • Electric shocks happen because electrons pass from one object to another • You get shocked because atoms want to be balanced • You get shocked more in the winter because the air is less humid

9. Current Electricity • The constant flow of electrons are current electricity • For example a pencil sharpener

10. Conductors and Insulators • Conductors- a material in which electrons can pass simply • For example metal • Insulators a material in witch electrons cannot pass through • For example rubber

11. Closed Circuits • Closed circuit- a endless path that lights up a light bulb • To make a closed circuit you need something that pushes electrons through the path. An object that allows the electrons to flow through it. Wires must connect the path of the circuit. if a circuit is open the object will not work.

12. The Light Bulb • For the light bulb to work you need electrons to flow through the copper and into the Togs tin

13. Series Circuit • A circuit that connects several items in on path • It is not always good because if you turn one object off you will turn off every object

14. Parallel Circuits • A circuit that connects several objects each in it own path • It is good because if you turn off object off the others will still work

15. Safety Tips • If not used correctly it can cause burns, shock, and even death • Don’t put your fingers in a outlet, don’t touch a wire without rubber on it.

16. Magnetism • A force that attracts cretin metals • Each magnet has an invisible magnetic field around it • Each magnet has a north and south pole the poles are the strongest in the magnet • Opposite poles attract like poles repel • Not all conductors are magnets

17. The Giant Magnet • The Earth is the worlds largest magnet • The Earth has 2 poles North and South • A compass is a frilly moving magnet the south pole of the magnet points to the north pole of the Earth

18. Electromagnet • When electrons pass through the metal it becomes a magnet • It is made by coil of wire rapped around a metal substance • Helpful: turn on and off, you can make it stronger or weaker

19. Electromagnet Uses • Electromagnets are in earphones, TV's, DVD players, fans, VCRs,

20. How Electricity Is Generated • There are copper wires around a magnet • The magnet moves around and causes the movement of Electrons • Power lines connect the wires from the power plant to our home

21. Famous Scientist in Electricity • Benjamin Franklin- the lighting rod, positive and negative charges • Thomas Derision the light bulb • Michael Faraday generators
