The first airplane was made by the Wright Brothers. The airplane is the worlds fastest way of transportation. If you use a ship or a car to get to far away places you will get there in a few days or weeks. But the airplane takes a few hours or 1 day.
Airbus A380 is the world's largest passenger airliner. http://en.wikipedia.org/wiki/Airbus_A380
It is also fun on the airplane because you can watch movies or listen to music. Their are many kinds of planes like space shuttle, an airforce plane, and a transportation airplane.

The Amazing Telephone
Now I'm gonna tell you about the telephone. The telephone was created by Alexander Graham Bell. Before the the telephone was invented, if people wanted to communicate to people far away they would mail letters. Then they would wait 20 or 30 days for a response. On the telephone you can call anyone you want and get a response on the same day.
Apple iPhone is the latest in phones:
With just the right transmitter in place sound could be carried over wires trough electricity varying in intensity and also transmits speech. He also tried to experiment with a water transmitter using an acid-water mixture and he succeeded. Unlike the telephone which couldn't transmit speech clearly the water transmitter sent speech perfectly.

The Wonderful Things About Electricity
I read a book called Inventors by Martin W. Sandler. I'm going to write about my 3 favorite inventions and their inventors.
First I'm going to tell you about electricity. Electricity is important because if we didn't have electricity we wouldn't have lights.
Before electricity people would use candles or oil lamps instead of light.
The person who invented electricity is Thomas Alva Edison. He invented many things but his greatest invention was the light bulb. He discovered electricity when he was flying a kite into a thunderstorm and his kite got zapped so the lightning reached Edison by the string attached to the kite.
Light is important because if we didn't have a stoplight or a walk and stop sign, it would be a disaster. Everything around us like computer, lamps, and television work on electricity and light.
