History
By Andrew
Electricity has been important to humans for many years. Around 500 B.C. a Greek philosopher named Thales first discovered electricity when he learned that when amber is rubbed with cloth, small bits of straw are attracted. Queen Elizabeth, the Queen of England, discovered that diamonds, glass, sulfur and wax act like amber.

In 1706, Benjamin Franklin a famous scientist was born. In 1746, Ben Franklin started experiments with electricity. While trying to prove lightning was electricity he flew a kite in a lightning storm with a key at the end and the lightning touched the key which made a spark. From this, he made a metal rod to go on a roof so the houses would have no damage. |
| In 1847, Thomas Alva Edison, probably one of the greatest inventors, was born. He invented the phonograph, telephone, vacuum tube, electric light and helped perfect the motion picture. He died in 1931. As you can see, many inventors can find something out while doing something different. |
