  1. Electricity Grade 6 Science

  2. Energy Energy: The ability to do work Energy makes everything happen and can be divided into 2 types • Kinetic energy- moving energy (turn on lights on) • Potential energy- stored energy (battery) Energy is measured in Joules

  3. Matter All matter is made up of atoms 3 states of matter Solid Liquid Gas

  4. Parts of an Atom 3 main parts of an atom Neutron Electron Proton Neutron: Neutral charge Found in the nucleus Proton: Positive charge Found in the nucleus Electron Negative charge Spins around the nucleus

  5. PARTS OF AN ATOM

  6. Opposites Attract and Like Charges Repel(+) (+) = Repel(+) (-) = AttractWhen 2 oppositely charged objects attract or pull toward each other, it is called an electric force

  7. Atomic Number Number of protons and electrons= atomic number on the periodical table of elements

  8. Bohr Rutherford Diagrams Shoes how electrons are arranged in an atom First level = 2 electrons Second level = 8 electrons

  9. Static Electricity Electricity that stays in one place It may result from the transfer of electrons from one object to another

  10. Balloons One way electrons get transferred is through friction. For example, when you rub a balloon against your head, electrons in the atoms that make up your hair rub off onto the balloon.

  11. Nikola Teska 1891 he invented a wire coil which could recreate the effects of Lightning Known as the Mad Scientist Tesla coil: been used to develop X-Ray Wireless Radios Televisions Remote controls

  12. Dryer Sheets Clothes tumbling inside a dryer creates Friction Dryer sheets reduce static cling Specific coating that softens your clothes and reduces the amount of friction

  13. Lightning Rods Lightning: fast movement of clouds collect a large charge The negative charged at the bottom of the clouds are attracted to the positive charge on the house When the charge is too large the cloud releases a spark and it races to another cloud or the ground Large Scale static shock! http://video.kids.nationalgeographic.com/video/player/kids/forces-of-nature-kids/lightning-101-kids.html http://www.youtube.com/watch?v=2wY_t7zVIXY

  14. Benjamin Franklin Benjamin Franklin studied electricity, and is quite famous even today for his kite and key experiment with lightning. We must always remember that Ben could have been seriously injured during that experiment. http://www.pocanticohills.org/franklin/lightningrod.htm
