How Does Electricity Work
.
* Metal atoms are arranged in orderly rows and colums. Inbetween the columns are electrons which are able to move around. When we apply a voltage with a battery, we draw electrons so they move collectivly in one directions. Making electrons hop from one atom to the next, which is the wire we see in power cords and across telephone poles. All metal can conduct electricity, but copper is one of the best and very abundant. Copper is easy to bend and stretch, it's too soft to make a blade or sharp electrical part on its own, so bronze or tin is added to give it strength, meaning the copper atoms are unable to wiggle and squish around.

History of Electricity Timeline
.
A lot of Timeline info from: http://resources.schoolscience.co.uk/britishenergy/14-16/index.html
* Electricity has been around forever and will likely be around forever.
* * 600BC: Static Electricity discovered. A Greek named Thales noticed rubbing amber and silk, would attract feathers and light objects.
* 1600: William Gilbert first described the Earth's magnetic field, and that magnets are related to magnetism. Invented the term electricity.
* 1705: Francis Hauksbee invented Neon Light. Placing mercury into a glass, pumping out the air and spinning it, then rubbed it with his bare hand.
* 1752: Benjamin Franklin, a U.S. politician, proved lightning is electricity. Flying a kite in a thunderstorm.
* 1700's: Wimhurst Machine invented. Used to produce static electricity easily and reliably. Two plates rotating in opposite directions. Collecting the charge in a comb-like device. Producing four inch sparks, and 50,000 Volts.
* 1780: Luigi Galvani discovered that dead frog leg muscles twitch with a bit of electricity.
* 1800: Volta invented the battery. Using pure silver and zinc discs, sandwiched between muslin damped in a salt solution. Developed from Galvani's earlier experiments.
* 1800: Sir Humphry Davy discovered Electrolysis. Decomposing some substances by passing an electric current through them. Leading to the discovery of many elements including magnesium, calcium, strontium, and barium.
* 1820: Hans Christian Oersted discovered magnetic fields. Electricity through a wire, effects the needle of a nearby compass.
* Michael Faraday discovered when a magnet is moved within a copper wire coil, a tiny electrical current travels through the wire. Eventually leading to the discovery of electric motors.
* 1821: Thomas Johann Seebeck discovered Thermo-electricity
